    I came across this video when I was looking for something else and thought I would
    share, this is for information purposes only ! I would not recommend doing this on any valuable coins how ever maybe on something that you dug up in the back yard or
    found on the street it works pretty good :)

    Might work on some crusty ancient pieces.

    It's a cool system. If the coin turns out too dark, you had too much amperage. I had trouble with turning silver dark.

    It is very cool! I think one of those supersonic jewelry cleaners or denture cleaners would yield better results. I've owned a few large cents that have been through electrolysis, but they always seem to be very porous and pick up weird color.

    This guy knows what he’s doing he’s very
    complete with the process using sea salt
    instead of using table salt.

    It works better if you put your finger in the solution, just kidding. Thanks for sharing.

    Don't forget your eye protection. And maybe a blast shield.

    I think most already know this but for those who don't - using electrolysis or any ultrasonic cleaner to clean coins can easily and permanently damage coins.

    Using these methods is not recommended.

    I agree but there are exceptions. In many cases you have to choose between and unidentifiable slug or a coin of some sort. Traditional chemical methods are slower and often not very effective. No matter what - end result will be a damaged coin but at least you'll have a coin.

    I always figured if I ever tried it I would very tightly control the voltage/current using a proper electronics setup. The reaction is very easy to visually observe and if you gradually bring things down as it progresses, you can minimize the surface damage. If you go very slowly and keep a close eye on things, electrolysis can be very effective on heavily encrusted materials.

    And I have no problem with using it in situations like what you describe, for in those situations there's not much you even could do to make things worse. But in other situations I would avoid it.

    In a way electrolysis and sonic cleaning are kind of dipping a coin - a decision has to made. There are times when a coin should be dipped, and other times when a coin should not be dipped - and it's up to you to know the difference.
