 If you're considering rinsing off a paper object or maybe a photograph, and it's a single layer, just one photograph, not a stack of photographs stuck together or in an album, you'll want to make sure you give that some support. You can put it on a piece of plexiglass and put it at an angle, and then use a hose and spray the front of that object and then turn it over into the reverse side. If you have books that have mud on them, don't open the book up when you go to rinse it. Make sure you hold that book closed really tightly, and you just want to rinse off the cover and just give that a good rinse. You don't want to deal with trying to open that book up and rinsing individual pages because once again they're paper, they're very vulnerable.
