Is acetone safe for clad coins?

I was wondering if anyone has had any experience soaking clad coins in acetone, and that the results were.

What about e zest, is that safe?

Thanks again for your help :)

    Yes, acetone is safe. Just be warned it might reveal the monster below that gunk… >:)

    Acetone, yes. Unless your coins are made of plastic, acetone should be harmless.

    E-Z-Est, no. It's tarnish remover, sulfuric acid-thiourea based. Designed to not cause too much corrosion to silver coins, but will readily corrode non-noble metals.

    I’ve tried E-Z-EST on clad silver, with no ill effects. I would be careful with clad though, as it can turn the copper on the rim pink.

    Acetone is non-reactive on all precious metals. Dipping in EZest should be done by a second count. Followed by a distilled water bath. Don't use on copper. Good luck. Peace Roy

  • Thanks for your help, I found a really nice 1969 proof quarter with a double die, but it has a little junk on it (I can see something through the plastic),

    So when I crack that baby out, I want to try and see if that gunk can come off :)

    I would like to see before and after photographs if you care. Thanks.

    OK, it really works: ammonia on copper nickel - no dyes in it though. Try first with 1:1 water dilution....Follow by light detergent and liberal irrigation with water and tamp dry with high nap white cotton towel. I do it all the time with very good results.
    Try on a regular quarter that has some "schmutz" and you will get a feel for what is NOT a tricky process.

    Well, just Love coins, period.
