 Susan Berger, go ahead, Susan. Hi, everyone. I want to greet you here. I hope you're all having a festive time since Halloween. I just want to remind you, the course deadline is November 8 at midnight. And if you're looking to get a credibly badge, you need to listen to all the webinars, complete all the assignments, including passing the quiz from last week. And right now, I think there are two or three people that have done the quiz but not passed it. And so you need to go back and redo it again. You can do it as many times as you want. But you do need to pass it. So if you have questions about the mechanics of the course or other problems, you can contact me. This is my email. And if you have questions about caring for your collections, you can join the Connecting to Collections Care community and the instructions there on our website. And coming up, at the end of this month, we have a webinar on LED lighting from museums. And in early in December, we have one on insurance. So be sure to check those out. And I'm now going to turn this over to Gretchen Anderson. Go ahead, Gretchen. Go ahead, Gretchen. Hello, everybody. Hello, everybody. Today, you're going to have Paul Storch speaking to you about developing a music, I mean, a housekeeping plan. And I also want to underscore that you need to pass all of the assignments. I think that you have gotten the PowerPoint that I put together about the hands-on assignment. Please go through that and try and get caught up. And you need everything by midnight, November 8. So let me turn it over to Paul. Here you go. OK, let's see. Get the slides up here. Well, you'll have to bear with me a little bit. I'm still getting over a head cold. So it gives me a little more of a radio voice, but I'll do the best I can. So I'm going to try to tie everything together from the previous three weeks. Excuse me. And doing that, I'll probably refer to some of the things that Gretchen and Tara talked about, but I won't get into the technical aspects of those, because you've already gone over that, but mainly going to how they all come together in a cleaning plan, which the title is Standard Operating Procedures. And my orientation, I'll give you a little bit of the background, is in objects conservation. And for the past 10 years, I've been collections liaison, basically a collections manager for the Historic Sites Network here at the Minnesota Historical Society. And I've also done about 30 years of consultations to different types and scales of county and local historical societies and museums, mostly in the Midwest. So in putting this together in my talk today, I'll be keeping those situations in mind of smaller museums, as well as somewhat larger in places and institutions and drawing from my experience with the Minnesota Historical Society. And also, this is a caveat, some of the illustrations you'll see in my orientation, of course, has been with historic sites. But what I'm going to be talking about can be applied to regular museums and collection storage and those types of areas as well. So let's get into the whys and watts of cleaning plans or historic housekeeping plans. You'll see both written here. Why? So the housekeeping plan fits in with building maintenance, sound security practices, environmental monitoring, disaster planning, IPM, and overall collections management in a preventative conservation approach. And I refer to that as really the first level when you're thinking about developing your plan and implementing it. It has to be collaborative with the facilities, maintenance people, and custodial. We're involved, of course, with collections, and that's what really we're talking about. But it has to be in concert with what's going on with the building envelope. And I know Gretchen talked about that in her earlier lecture about the different layers within or around your collections, the building envelope, and then the different rooms and storage devices and things like that. Well, the first level would be the facilities having their maintenance plan. So maintaining systems, maintaining windows, doors, door sweeps, all that. We'll get into that later and show some illustrations. And then what we'll be doing and the why's and what's pertain to the second level of collections, maintenance, and collections cleaning. So another why is museum objects and historic spaces have different cleaning requirements than modern buildings and equipment. And again, they go hand in hand. And the cooperative plans work together. And then what of the housekeeping plan? It provides a framework. And as you'll see, we'll develop a schedule, preventive maintenance, and preventive treatment. Reinforcing what I just said, buildings are part of the collection. I just wanted to throw this slide in here. This is one of our historic sites showing it's a mid-19th century Fort commissary in Minnesota. And the wall has some issues with efflorescence of the stone in the mortar. And you could see some white on the floor there. So that's in the exhibits gallery. So the site staff has to work with facilities in controlling the environment in the building. And their role is, of course, cleaning up the efflorescence. In this case, it hasn't impacted any collections directly, but we're working together to solve that problem. Now, getting into the components of your plan, really the most essential part of this is an assessment, if you haven't done that already, would be to assess the nature and condition of the overall collections and exhibits. So that would be a general assessment, not really talking about object by object at this point, but looking at the space and starting at how is the space used. So this could be a gallery, historic building, historic house, furnished or not, which would include programming. So open hours is used for a lot of school tours, special programs, evening events, rentals. You need to keep that in mind as well, a lot of sites. Especially recent years and going forward, museums have to be entrepreneurial. So those kinds of things, you have to consider how they're going to affect the collections and preservation and adjust your cleaning plan and maintenance plan accordingly. Then the overall building condition, going back to what I just showed. And I don't want to get into deeply into facilities maintenance. That's another webinar. But the roof conditions, pointing, those kinds of things, windows, of course, that's all going to affect what goes on on the inside, obviously. So you want an assessment of that, and that may trigger projects for someone else. But it's good to get a collections-level assessment of how that affects interior conditions. And then a sense of the accumulation rates of soiling, of dust, and strictly empirical observations, how often have you been cleaning? And again, that's going to be dependent on various things, getting back to how the space is used. And I'll talk about this a little more going forward. But are windows and doors used for ventilation during certain times of the years that's going to have an impact on accumulation rates and also depending where you're located with winter. It could involve salt coming in, depending on how much visitation you get, that type of thing. Then the next step would be identify routine housekeeping tasks as well as any special projects. And if you've had a long-range plan assessment from a conservator, say the CAP Conservation Assessment program that started back up or something that your state does, in Minnesota we have what we call legacy grants, where you can get a conservator to come through and do a general conservation assessment, which includes looking at the building envelope and all aspects of your operations, as well as the collections, and then the development of a long-range plan. And those include actions based on observations of, again, all different aspects that affect the collection. So we'll have recommendations for cleaning and observations on dirt accumulation and deterioration and those types of things. So incorporate that into the cleaning plan. And then identify equipment, materials, and techniques for the housekeeping tasks. And I'll show some examples of that. And then the next component of the plan, major component, is to assemble the housekeeping team and define responsibilities. So again, depending on the size of your institution, that it could vary. Maybe one or two staff or even one person, if that's the situation. But it's important to have responsibilities defined. And then getting into a tool to use would be to actually create a housekeeping assessment planning sheet. And this is the first step to it'll feed later on into your actual written schedules and the logs that kind of generated from this. But this is something, again, depending on the nature of the institution and the size of it and what kind of components you have, you could do several sheets. It doesn't have to be one for the entire museum. So say you have a county museum building with gallery spaces and storage areas. But then you also have a small historic building on the site. And to make it even more complicated, a steam locomotive outside that's also a display exhibit component, say. Or you can think of that as an exhibit gallery if people can go into the cab. So each one of those components is going to have its own specific housekeeping needs. So I think it would be germane to do an assessment planning sheet for each one. If you just have a museum building, then you can break it down for the galleries and the storage areas, because you'd have separate schedules for those we'll see later. So the basic components you see listed out here. And I want to just pause for a minute. This is what I set up as the assignment for this week. So I'd like to see each of you create one of these. And you could just do one if you have multiple areas, like I said, just maybe concentrate on one. And it's something that you'll be able to use. So each item is referring back to the last slide, the major components. So what you do would be to list the location or the name. In this case, I was thinking of a general store that we have in central Minnesota. So it's the name of the site and then the use. And in this case, I have open seven days a week. Basically, what's the program? So we have guided tours, self-guided visits, drop-in visitors, and school groups. And then you want to list, OK, when is that? Generally with our sites, those visits are heavy in the spring and the fall. Some may get summer camp visits or actually do their own day camps. So that has to be put in there because that's going to impact the amount of cleaning, that type of thing. Then just a general listing of what kind of collections. And again, for your purposes, you could alter this and add topics if you need to that are more specific to what you're dealing with. But this is really the main things that I use. And I'll be doing this for our sites as well. It's a very handy planning tool. And it could be updated when as needed. So collections, permanent collections, POMS slash touchable. POMS is the abbreviation we use for program use materials. So those are non-accession materials. And some are expendable, get used up, thrown away. They may have come from the accession collections from sites and redistributed, or in our case, through our network if they make more sense in another site like clothing, for instance. And they can also be somewhat high value. So in that case, you'd want to consider them a little more like collections. And then how are the things displayed? So in this particular store site, we have objects on shelves and counters. And suspended from walls and ceiling, that's all going to impact cleaning, as you'll see pretty soon. Operation, it's probably not the best term. You can find one that works a little bit better. But what I mean by that is, how is the building operated? What kind of systems are going on? And what kind of actions that affect the environment and cleaning? So forced air, heat only. The window, again, like I mentioned before, windows and doors open in summer for ventilation. And then I put, as far as management of the environment, we have a data logger in the storage areas. Then light consideration. Shades are pulled when the site is closed. They're open during visitor hours. And then if applicable, we have a wood burning stove used in the winter. Of course, that kind of program operation has a lot of different impacts, safety, bringing wood in for use that ties in IPM, all kinds of things. But listing it here is it could possibly generate some soot on the walls and ash, that type of thing. So in talking about dirt, that's why I listed it here. Then dust levels, dust accumulation levels would be the sources for that. We have an unpaved parking area in front of the building. So wind is going to bring that in. That's going to have an impact, particularly in the summer, and increase the rate of accumulation. And a road about 100 feet. And then also something to think about is what's going on around you in the general neighborhood. And several other sites are located in farming areas. And besides obvious wind-blown dust, it impacts pest load, especially in the fall, when harvest occurs. We get a fair amount of Asian ladybugs coming into the sites. And I've got some slides of that. So that's something to think about as well. And then going off that is just a general assessment of the insect load on the site, in this particular place, ground-hawk activity, birds, squirrels, et cetera. And I mentioned the box elder and the Asian ladybugs and, of course, the ever-present mice. They want to be cognizant of those. And then equipment needed. You want to list that for a particular area. So usually a HEPA vac, brushes, brooms. I know Gretchen went into that. But when doing the assessment planning sheet, consider what you'll need for a particular area. And then the next major component is the who, putting together the housekeeping team and what are the responsibilities for who does that and actually does the work. So to create the plan and the schedule based on the assessment observations, that usually would be the museum director. If it's part of a standalone site, part of a network, the site manager or curator collections manager would actually be the person in charge of getting that set up. And then the actual tasks usually would be a site supervisor or a historic housekeeper. Of course, some of the tasks, as I mentioned, would be the facilities, custodial people, if you have that, or exhibit staff for maintaining the gallery exhibit furniture, the displays, vitrines, those type of things. So they would be the people who would carry out actual cleaning and maintenance tasks on a regular basis and also responsible for documenting the tasks and reporting any kind of problem. And then the role of conservators, if they happen to be on staff or you use contract of conservators, would be to provide overall advice, occasional assessments, and then actual treatments when needed. Then developing the team, you specify cleaning responsibilities in position descriptions. So establishing the percent of work duties and time involved with cleaning and maintenance activities. Now I talk about PDs, and that generally refers to paid staff. I know some smaller institutions would most likely depend on volunteers, but it's good to have written responsibilities for volunteers as well. I know a lot of institutions actually have position descriptions for volunteers. So the expectations on both sides are pretty clear. And if it involves collections maintenance, then it's good to have that written down and established. And the science tasks and work into a regular schedule so cleaning doesn't get pushed out when other things come up or it should be established as a main priority and incorporated into the regular work schedule. And then training is part of team development. And it should start with basic object handling, training, and then more specific or general and specific to the object materials, provide equipment and train on use, and provide personal protective equipment. And Gretchen and Tara definitely talked about that in terms of hazardous materials and collections and dealing with mold and all that. I won't go deeper into that, but all those considerations should be taken into account when setting up the team and providing equipment for it. Then next step would be cleaning training, something I suggest is setting up a training session or sessions with using didactic or program use, the POMs, or deaccession to objects for practice. It may take a little time to develop that in-house, but once you have it and you get new volunteers or new staff, you've got a set of materials to use. And you can do anything from dry cleaning all the way through wet cleaning and use different gamut of what representative materials you have, so metal, leather, wood, ceramics, a glass, that type of thing. You can do the different methods on it. And then there are available videos and webinars online. Another way is to have existing staff train, new staff and volunteers, somebody responsible for that, or bring in trainers if you don't have the expertise available on staff. And you can also utilize state historical societies, if possible, and conservation center workshops, and bring in trainers. Excuse me. And then getting into the written procedures, the what. So you want to have listed the locations for cleaning and housekeeping, the list of tasks to be performed, and then specific techniques for each task. And I'm going to have illustrations of this later. I'm just going over the main points right now. And then the frequency and schedule of each task. So it's daily, weekly, bi-weekly, monthly, and annual, semi-annual. The name of who is responsible for those tasks, name or names, and then, again, supplies and equipment needed. And again, of course, the procedures may vary if you have multiple different, widely different locations, you may have to have a specific written procedure for each one of those, rather than just one for the entire institution. There's some illustration of identifying and dedicating equipment specifically for collections, cleaning tasks. So in some cases, you might have a set of cleaning equipment tools and supplies and vacuums just for the collections, cleaning or for the historic house areas, cleaning separate from the custodial and the public area cleaning equipment. They don't get cross-contamination, that type of thing. So this is, on the left, is a dedicated bucket for historic room cleaning with Kim wipes and static quarts, brushes that you want to keep clean away from the food materials that type of thing. And then vacuums on the right, a canister backpack or helpful for historic housekeeping and the regular upright for the floors. And then getting more deeply into actually developing the schedule and the actual plan, looking at prioritization. So the example I'm using here is a historic house. So again, your first level, there would be more frequent daily and weekly, at least. And of course, depending on the programming and if there's a rental schedule in place, maybe even more frequent, those would be the custodial tasks. So all the public areas would involve trash, removal, sinks, bathrooms, the non-collections, carpets. And also something to think about that, too, if you have catering activities going on at the site that the vendors and caterers be given a fairly strict protocol for their cleanup, as well. And that somebody from the institution is available to make sure that that gets done. That's a big component of cleaning and housekeeping. Then the historic cleaning housekeeping component, the daily would be to dust, vacuum the historic rooms and rotating order. And as we'll see, starting with the exterior. That's an important, especially here in Minnesota this time of year, particularly with school groups. That's a main source of dirt and leaves coming in when the groups come through the front door and track leaves and other tree parts with them. So the first thing the housekeeper does in the morning is to sweep the porches. So that's like your first point of protection for being proactive. And then bi-weekly dust tops of all doors and door frames. Weekly to bi-weekly clean dust, wash the entryways, big glass panels and doors. And again, that depends on use. Maybe with school groups, you might get more fingerprints on glass. Weekly brushing, dusting all the window shutters. Then more monthly would be the vacuuming collections carpet. And something we've found that ties into pest control is wiping and vacuuming all the window sills and frames to remove bug carcasses, particularly box elders here. Because they, as you probably know, can provide food source for secondary pest infestations of things like dermestids or other collections, more serious collections pests. So that's something we kind of found out by experience about 20 years ago and really stepped up to cleaning that that was an area that was being overlooked. And since we've been doing that consistently, we really haven't had any major infestation. Then semi-annually would be dusting all the walls and ceilings, if applicable sponge using a sit sponge on the walls near the stove that's used for cooking programs easily, changing table covers, and then cleaning and waxing wood details to some illustration on the lower right of the daily front porch sweeping, your red leaves, and then vacuuming the windowsills, particularly this time of year that's more frequent. Then continuing on prioritization, illustration of annual, the more detailed type of cleaning would be light fixtures in some of our sites that involves taking down chandelier crystals, and that's a major project where site interpreters are pulled into that and are trained on doing that. And that also gives you an opportunity to closely look at the ceiling structure if there are any structural problems with that. In one of our sites we have plaster rondells, and we had an issue with some of that actually separating from the ceiling, and that was noticed during the annual chandelier cleaning. So all this ties into preventative conservation of the site itself as well. So light fixtures and then wash all exposed glassware in China, wash or dry clean all curtains and drapes, wet cleaning painted woodwork, and wet clean all non-carpeted floors and wax if needed. Now in some, depending again on the situation and visitation, that may be twice annually rather than just once a year for the floor cleaning and waxing. We have one of our sites is a very popular lighthouse, and they get over 200,000 visitors a year, so they need to do that a little more frequently. Then as far as responsibilities, for the cleaning personnel would be to carry out the tasks as assigned on schedule, observe and report changes, problems with objects, any kind of water issues, temperature, fluctuations, problems with humidity, and of course pest issues. And then it's important to completely fill out the logs. And again, how you establish that is up to your particular situation. But whether it's done online or in a paper form really doesn't matter. I think with Google Docs now, that's what we're using with our sites, facilities, maintenance, and housekeeping staff as they do a monthly Google Doc report. And we have a monthly full department meetings. We go over those and discuss any issues and projects. They may impact that. Then it should be responsible for properly maintaining cleaning equipment and reporting any problems with that or needs for repair or supplies, that type of thing. And then replace parts and supplies as needed. Properly dispose of collected dust and debris. And again, those were touched on in the earlier lectures for that. I don't go too much into hazardous materials in this, but that needs to be a consideration. And then follow proper safety precautions during cleaning and for the use of the equipment. All right, moving on a little more specifically, what's the cleaning schedule? And again, one size doesn't fit all. So the actual schedule needs to be based on your assessment observations and could certainly be modified when circumstances change. And schedules need to be realistic. As I mentioned before, with galleries and separate historic buildings having their own schedules and logs. So to review base your schedule on reality, the visitor load programming, problem areas, seasonal demands, window and door use, as I mentioned, and then ongoing variations in dirt dust accumulation. And then the schedule would include the cleaning log with the date, time, name of the person, any collections condition, insect observations, and changes. And then one form that we've used here at MNHS would be sort of a setup form that you'd use for developing the schedule. You can make use of this or not. Again, I apologize for my voice. So this would lay out your actual locations and you could break it down, in this case for a gallery, to where if you have very different types of objects, say some in vitrines, some on platforms, open air you'd want to have slightly different cleaning methods for those and different schedules. So this breaks it down and kind of lays it out for further planning. Hope I can make it through here. Then your actual cleaning log, and again, this is a very rough sketch of one. You could develop one that works best for you, but it has the basic components on there. Again, it's the room gallery. In a house you'd have each room. You could use the name of the room or room we like to use, room codes. That tie in to our collections management system, room location codes. And it just lists how the form is to be used up at the top. And the date, of course, is important. Just a brief description of what action you took and who did it and any kind of observation notes. So that's main components of your log. And then this, I know that the print's probably a little bit small on this, but it shows actual housekeeping task list that we use at two of our historic sites, Ransey House and Sibley House. And this breaks it down again as I talked about before, the custodial activities at the top, and then by frequency. And then the historic housekeeping, you start cleaning for the house and the carriage house and then it has specific task activities actually spelled out, and then the frequency of that. And you'll see some of them are weekly, weekly and bi-weekly here, and just the continuation of that. And then just some actual examples when we talk about practical applications. This is actually the fourth commissary site. Another area of that same building. And these are actually program use materials, but I think it's illustrative of some exhibits may be similar to this. Generally, if it was actual collections, we would have plexi cover on the display here. This is open since the materials get handled. But for cleaning, probably parts of it would be done on a weekly or bi-weekly basis, the horizontal areas. Some of the materials would be moved out, so that would probably be best done with two people where you'd set up a small table next to this and then one person would hand the objects to the other person, clean the horizontal areas, do some light surface cleaning of the objects. Then the textiles could be done maybe semi-annually or annually where they have to be taken off the mannequin, moved out since a little crowded in there, and vacuumed under a screen. Something like that. And then this is a replica howitzer here that's surface cleaned and maybe once a year a little more deep cleaning on that, but at least to get the dust off the wood and metal components on a regular basis. Furnished historic is more typical of our mid-19th century houses fully furnished. In this picture the rug here is actually still the original. We've since taken that off display that's now stored in one of our warehouse storage spaces and we have a replica down, but even the replica for visits, we have carpeting that visitors walk on to protect that and cut down on soiling, but that would be cleaned annually and we cleaned the replica rug because a high value program use material would be or is cleaned the same, with the same care as we would originally want that to last. And then the smaller objects would be cleaned monthly or so with the monthly dusting, say the wood surfaces, and then with the annual schedule to take the smaller objects off this round table here and then clean the textile and then the surface and the more detailed cleaning of the wood details would be done most likely annually. Something that's a little more specialized I thought I'd mention would be full-sized diorama cleaning. That's one of the things that our MLAX Indian Museum site in North Central Minnesota, that requires definitely a team to go into dioramas. We do that once a year or so. Also for past inspection and inventories. That's a team effort that's specialized padded boards because we've got these woven mats. You can't, you don't want to step on those directly so we lay a padded plywood board and you crawl on your knees to get you safely over the mats and into the further end. The wigwam here is dirt floor or simulated dirt floor so once you get in you can walk around in there but that's just something to consider when I talked about developing or listing specific cleaning equipment for each different type of collections area. This is an example of that. Also that brings up, and this example as well would be a longer term cleaning activity which would involve cleaning the shelves, the horizontal shelves. But it's something in terms of developing your schedule in coordinating cleaning activities especially the longer frequency ones with inventory and rotations work. The actual example is just doing a periodic inventory at this site and worked in taking the plexi cover off and cleaning the shelves, taking all the objects down which we had to check numbers anyway for the inventory and also rotating some of these fans off display. So that's something to think about as well when developing your schedule is work it in with other collections activities like inventory and rotation. Then just another example of gallery. This is another one of our Native American sites, Lower Sioux Agency. It's a partnership site with the Lower Sioux community and it has a couple of full-size dioramas, the objects of the trains, and then out of the slide on the right is open platform storage with large objects. So it's a variety of cleaning tasks and scheduling here. The site partners would do the vitrine, the regular custodial and vitrine cleaning. This is plexi cover on some objects here so that has to be cleaned most likely daily. Annually I'll go to the site and go into the diorama here in the wigwam and clean that. There's a variety of frequencies and a cooperative project. And then special displays. This again is the same room with the fan display case over here. The rug here is original to the house so that gets cleaned by our conservator once a year using, well, we do have a maintenance, a collections maintenance assistant that works on that as well. And then these matic textile mannequins are rotated every year. So we'll do less cleaning on site of these, just be periodic inspection, but then once they come off display, they would go back to the conservation lab and be cleaned before putting back in storage. So that's just something else to think about if you have temporary displays. And then just kind of tie up some areas that could be easily overlooked, particularly in a historic house. They're corners, corners and tops of moldings so it's important that they get put on the schedule. Addicts and basements again even if they're not used for programming or even storage, they should still be on the regular schedule, particularly in the pest season. And this situation has changed since I took the slide. The window's been fully restored so we don't have the kind of pest you can see on the floor here. The carpet and pieces of wood have since gotten out and that makes cleaning a lot easier and inspection and removes harborage for tests. And then again, program use areas may require more frequent cleaning, particularly if the stove is used and there's programs involving food so that needs to be on a stepped up schedule with some special care taken on that. Then just getting some illustrations of what would be annually cleaned would be ceramics glass. But again, base that on actual dust accumulation. Also if you have on-site storage, in this case textiles, that could be annual going through and then that's a good idea to tie that in with a spot inventory at the same time. See if anything's been moved around or things pulled out for display and they've been put back properly so that's something that could be done on a longer term basis. And then a more specialized cleaning, which would be more of a conservation level, would be the silver in this cabinet at a historic site where the ceramics and glass pieces here can be done on-site. If we were going to do the silver, that would have to be packed up, transported to a conservation lab and probably looking at every five to ten years depending on the pollution level in that particular area, how fast it would break through the coating. Generally these things are given a spray coating, a lacquer, and that could last, as they say, five to ten years. So that would definitely be more of a conservation level. So touching on further resources and the role of conservators, that would be beyond what you would be doing with a regular cleaning plan to utilize conservators through a conservation assessment program or the state equivalent. And they can find, or their role would be to find problem areas with the building and interior objects that then you could use to feed into your cleaning plan. They could deal with acute pest infestations or damage if needed, freezing treatments, anoxic treatment, that kind of stuff that I know the others talked about. Conservators can assist with improving mounts, storage equipment if needed. They would come in and stabilize objects to allow for safer handling and cleaning and recommend based on their assessment when objects should be removed from display. So that's kind of information that conservators could provide. And then I've got online resources, and this is in the handouts as well. And then we talked about the assignment. So that's about what I've got, and we could go ahead and take questions. I don't know that there have been any questions. That was very thorough. Does anybody have any questions? No, I'm not either. Okay. Yeah. So Paul, Mark Anderson is going to give us a question. But Paul, you want people just to do one sheet for one area? Yes. Well, I think they could do more if they wanted to. But I think for the assignment, one is fine. Okay. Mark Anderson says, what type of wax do you use on the floors of the historic building? Yeah. We prefer the... I'm getting an echo here. Okay. I will undo myself. Okay. All right. That's good. I'm having enough trouble with my voice, so the echo just makes it even harder. A carnauba-based paste wax. So the brands we use, if you can get it, is Butcher's White Diamond Bowling Alley Wax. An equivalent is Johnson's Floor Wax. It's the flat yellow can. Those are mixtures of carnauba and beeswax and microcrystalline waxes. They're very hard and made for use, that level of use. Cleaning, just for regular dirt removal, Murphy's oil, a few drops of Murphy's oil soap, and then a rinse, let that dry, and then apply the wax. And trying to think if we do use mechanical buffers, sometimes just hand buffing is fine. But that's what we've developed for the use at the lighthouse, and that works for us. There are a couple of more. Jessica Noyde says, should you remove wax previously applied? What's the best method for removal? Right. Well, if you have wax, a lot of wax build up, generally it wears off on its own, but that would generally a little bit of, well, the Murphy's oil soap with a little bit of ammonia added and mop that off. That should work. What about waxing furniture? Yeah, I didn't have that in the... Okay. Thank you. I didn't show that and put that slide into this presentation, but we use the Renaissance microcrystalline wax for furniture that isn't heavily touched. Now, for things like handrails or handling maybe that gets used, doors, the butcher's wax can be used on that as well. I should mention that butcher's wax is in turpentine, so that could be used to remove build-ups as well. The microcrystalline, the Renaissance, is in a mineral mixture of mineral spirits. It's just something to think about with use with health and safety if anybody is a little sensitive, some people could have sensitivity to turpentine just to consider that who uses it and when it's used to do those kind of maintenance activities if you have a day or so before the site is open so you don't get people coming in that may have issues with that. Just something to consider. Gretchen says, would you recommend for washing dishes, et cetera? Okay. And my question is, I'm going to unmute myself again. For museums that are closed in the winter, I assume they can do some of these big cleanings, but if you have a museum that's open every day, how do you schedule around? Do you just close a gallery? Or how do you work around that now? I'm going to mute myself again. Okay. Yeah, for cleaning, general cleaning for objects would be a few drops of Orvis, the sodium laurel sulfate that's, I think it's even available from Amazon now, but we always got it from conservation suppliers like university products or talus, the gay lord I think carries it. And that's a general, very mild surfactant. So Orvis, it's even used for textile cleaning for the table covers and things like that. So that's what's recommended. Yeah, getting Susan's last question with scheduling, it would, yeah, if you're open, well generally places are closed at least Mondays. Most places have at least one day, so you'd have to schedule staff for that. You know, work that into your, if it's for annual cleaning or semi-annual schedule one day or like she suggested, close off a gallery. Yeah, with our sites it's less of an issue because we have seasons and then during the off season there may be groups. So sometimes, particularly for my inventory work I do have to work around the programming of the sites, but generally there's one day, Monday is usually the day that's closed, I think most museums do that. So you may have to break larger annual cleaning down into a couple of weeks. We have another question from Madison saying, how often should you clean dusting brushes and other tools? And how should you clean them? Yeah, well it would be best to do that, see how as soon as they get soiled, once they get beyond cleaning just replace them. But I would say, you know, if it's daily you may have to clean them after each use, vacuuming, probably to get the bigger particles off and then most brushes are washable. So you might want to have several or a set of them that you could rotate through or once drying. You've got the next one ready to go for daily, for weekly, you know, you do it when you're done by the next week it's dry. But yeah, I'd have a set so you could rotate those through. I think that's all the questions. Please click on this evaluation and do the evaluation. This is for the course. And remember that everything has to be in by midnight on November 8th. Gretchen, is there anything you want to say? And that means you have to have listened to all the webinars, done the assignments, and done the quiz, and passed the quiz. Gretchen, do you want to say anything? I guess she doesn't. Oh, here she is. Oh, I really just like the phone that they've given us. I think you've covered it at all. And the echo is horrible. Yeah, I don't like it. Oh, good. Now we all muted. Well, is that it? I just unmuted myself. So I think that that's it. So thank you, Paul. Thank you, Gretchen. Thank you all for participating in this course. And you'll have access to the course for a year. So you can go back and listen to the webinars or do whatever. But if you want to get the credibly batch, you have to, as I said, complete the assignments, do the quiz, and listen to all the webinars. And you need to do that by week from today. Paul. OK, and there's one more question about the quiz. How do we get, oh, OK, if you do the quiz and you don't pass, then it will tell you that you didn't pass. You have to get at least half of it correct to pass. So it's pretty easy. And you can just do it again. You have unlimited number of times. And I'm pretty sure you can click to get the answers. And all the answers are basically in Tara's presentation. So you can always look at the slides which are posted. So I'll post the slides for today's lecture later, and also the recording. And I'll let you know. Gretchen, were you trying to say something? Yes, I was. I'm going to mute myself. I'm catching up on everybody who's already submitted my assignment. And I'm trying to give you all good feedback on how you can go ahead with your ideas on cleaning that you're bringing up in the assignment. So as soon as you get it in, I usually do it in the evenings. I will catch up on everything and get it back to you as soon as I can. And I think that's it for me. Okay. Thank you, Paul. The feedback, yeah. The feedback, Don asked where does the feedback come from? When you do your assignment, the Gretchen makes comments on it, or other people make comments on it, and you should be able to get that through the education module. And if that doesn't happen, let me know, and I'll make sure that you know how you get it. I would get it through the education interface. Okay, so I think that's it. Thank you, Paul. Thank you, Gretchen. And thank you, Mike. Remember, we're going to have a webinar on LED lighting at the end of November and a webinar on a free webinar. Both of those are free on insurance in December. So thanks a lot, and we'll talk to you soon.
