The one thing I've heard is not to use nail polish remover it has other chemicals in it and will damage the coin . Use only 100% acetone. You can buy that at a local hardware store.

Agreed, only use high quality 100% Acetone from your local hardware store. but you can use water as well. but here are some more ways to 'clean' your coins. From one of our Moderators: Jbuck Quote:BadThad. He posted his recommendation to follow the polarity ladder (Water -> Acetone -> Xylene or Hexane) http://goccf.com/t/57008#447106

This is from another one of our Moderators: Sap Quote: Here's a quick summary.
Got something you think is "goo" on your coin? Do this, in this order: - Soak it in water. Rinse in fresh water. Let it dry. Is the goo gone yet? If not, proceed... - Soak it in acetone. Rinse in fresh acetone. Let it dry. Is the goo gone yet? If not, proceed... - Soak it in xylene or hexane. Rinse in fresh xylene or hexane. Let it dry. Is the goo gone yet? If not, then... too bad. It's not really "goo", it's actually corrosion. You'll need to switch to corrosion removers to clean your coin.
The ladder starts with water, because it's the most polar, and a surprising amount of real-world gooey things are highly polar and thus water-soluble. Sugars and starches, for example. Water is also cheapest and safest - no point in going straight to the expensive, hazardous solvents when water would work.
Now, if you know for certain that it's a specific kind of goo - PVC goo, for example - then you can jump straight to the solvent that works best for PVC goo (acetone), because you already know that water won't touch PVC goo. But for "unknown mystery goo", try the ladder.

Heads up micoin. These are some nasty chemicals. Be sure to take all the precautions and PPE. If you follow the instructions, you should be good. Don't use them in your house. I wouldn't. Stay upwind.

One thing I've noticed when using acetone with proof coins is that as the acetone evaporates from the coin humidity will condense on it. I use a blow dryer on the coin as the acetone evaporates to prevent that.

I have never had a problem with humidity condensing on a coin as acetone evaporates, but I am always in an air conditioned environment.  I always rise with fresh acetone, not water. I let the acetone dry on its own, it is very fast. Never needed to accelerate it.

Never use nail polish remover ever. Only use 100% pure acetone. Follow Dearborn's advice.

I know now not to use nail polish remover I bought on Amazon that says in big letters - 100% pure acetone - and in tiny letters on the bottle that I never bothered to read -Ingredients': Acetone, Denatonium Benzoate Unfortunately this is just another OOP's in a long line of them

micoin - if it states 100% acetone you are fine. When using acetone, I first soak a paper napkin or cotton fabric in acetone and then enwrap the coin in it for 10 minutes. If there still is something on it, then I let it sit in enough acetone to cover the coin. Just note that even with the recommended cleaning agents, you may not be able to remove such things as milk spotting (found on silver coins, especially those with very high purity of silver) without damaging the coin., Also any coin with attractive toning may suffer if exposed to acetone too long from my experience. That is why I first try the method of enwrapping the coin in an acetone soaked cloth. I have seen nice toning on copper/copper plated coins become uneven and less attractive if soaked in acetone. Not sure why so with these particular coins, proceed with caution.
