100% pure Acetone is the only thing I know that's safe if used correctly. Using anything other than 100% pure Acetone is harmful to the coin and will ruin it.

Acetone won't hurt a silver or gold coin and it will dissolve many impurities that are sitting on the surface, like dirt and PVC residue. It will not affect toning (patina) or remove metal from the coin. You only need to rinse the coin in cool, clear water after briefly soaking the coin in acetone. Put the coins on a sheet of aluminum foil to dry. Do not rub, or blot the coins with a cloth or paper towel. Since the surface metal is not affected, this will not cause the coin to appear "cleaned". Note that acetone will not "cure" or improve damage already present from PVC or from previous cleaning. It is just a solvent. The coin may still be rejected by third party grading services.
