REVERSE ELECTROPLATING SYSTEM TO CLEAN SILVER AND GOLD

[Socioistic]

You seem to know a bit about this, so I thought I'd ask you this.

Is it possible to reverse electroplate chrome? I have some guitar knobs that I would like to have in either copper, or brass (I believe it is solid brass, plated with copper, then the chrome, if I'm not mistaken), but because of the knurled diamond pattern on the sides, I cannot effectively sand, or sandblast the chrome off without being severely inconsistent.

@Socioistic I don't believe that you can do that. with an already plated object. I know some people have done brass alone but I don't recommend it. I believe that chrome is generally removed by an acid bath. You might want to talk to a commercial plating firm in your area. They probablly can give you an answer. Good Luck

Okay, I thought as much. Because of the shape, and the plastic inserts in the knobs, I'm guessing HCL, or whatever would be used to dissolve it would pretty much make them useless, so I guess I'll just pay more for some custom brass knobs. Thanks anyway.

I think you misunderstood, doesn't the stainless get attracted and deposited on to the coin? What keeps it from just going into, and staying in, the solution of saltwater? Thanks

@MrMaypole14

I did misunderstand. No, the sulfides from the coin are attracted to the stainless. It's a reverse plating process that removes the sulfidesthat have collected on the coin. The sulfides tend to come off in a cloud and deposit on the bottom of the container. Hope that is clearer. Good Luck

[MrMaypole14]

Aren't you plating the stainless on to the spoon? And, can you use household vinegar in the solution instead of citric acid?

[farenheit1100]

@MrMaypole14

The stainless does not get plated by the gold or silver being cleaned. It tends to erode. I nornally use citric acd or salt. I have not tried vinegar. The addition of the citric acid or the salt is just for conductivity of the water. I will have to try vinegar and see if it works. Thanks for watching.

Now the 12 volt adapter overheated after about 15 minutes X[

@chinchillaman1

A 12 adaoter us too small an output to use. In the later video I used an old computer power supply that is fused at a half an amp. The `adpter only puts out milliamps.

[chinchillaman1]

I built my own reverse electroplating machine, but you should have shown the silver after it was done. I used a 12 volt adapter and my silvers didnt come out so well =/ They overgrew with a black coating, the water and salt turned black and it basically ruined the coin with a bunch of tiny scratches. It also ruined a buffalo nickel YET, when I tried it on some brass buttons it came out like new. As I am writing this I am trying to clean a military dogtag made of copper from WW2 and its fine

[farenheit1100]

@chinchillaman1

The sulfides will overgrow If the process hasn't been done long enough or the power source is too low of an amperage. The method is effective on coins with heavy sulfides. The water turns black because of the sulfides. It will not do any more damage that the coin already has received. As far as the buffalo nickel, it is not silver and I never recommended using it on nickel only gold or silver.

If you dissolve 1 tablespoon each of table salt and baking soda in hot water, and put a piece of folded up aluminum foil in the bottom, all you need to do is put your quarter in the solution on the aluminum and it will almost instantly convert the tarnish back to silver and make your silver look brand new. Even if its completely black from tarnish.  That is by far the fastest, easiest, best way to remove tarnish. You should try it lol it is much easier.

Thanks for watching.

I missed this video mate. Going to give it a try on my silvers. Thanks for this. E.D

Thanks for watching. Good Luck and Good Hunting

[farenheit1100]

Thanks for watching! I am glad that you enjoyed this video. It is an easy way to clean without damaging the object.

[MichaelSwan66]

neat!

[OLDGOLD1100]

Interesting video!!. I have made the same thing, but i used an old 0 to 12v model train transformer. Yes, they do work very well. Thanks for showing us.

[farenheit1100]

@OLDGOLD1100

Yes, a model train transformer would work well also. I did this video because I kept seeing such nice coins in other people's videos that would look so much better if cleaned. Thanks for watching.

[OLDGOLD1100]

@farenheit1100 Yes, i like my silver coins very clean too.

[farenheit1100]

Glad you liked the setup. I didn't mention anything about the input voltage because the variable 15 volt dc output is the most important part. By varing the voltage you can control the speed that the sulfides come off. If you saw the video with the big Australian florin coin, it was cleaned with the machne. That coin was black when it came from the ground.

Awsome got to make me one

Thanks for showing us

You have got some amazing techniques! Your bag of tricks must fill a pickup truck! LOL!May have to try one of those basic setups i have seen in an auto magazine.No way would i be able to make one of those.Mine would probably work like an arc welder!

[farenheit1100]

@garbageguru1

One of the other subscriber's said that he used a power supply for an electric train. That would work fine and would probbly be cheaper. It is just a variable DC power supply. Just make sure that you connect the negative lead to the coin and the positive to the stainless steel or you will end up plating the stainless steel.

Good Luck and Good Hunting.
