[/B] Fingernail polish remover usually has perfumes, stabilizers to prevent the acetone from evaporating too soon, maybe limonene, the "lemon smelling chemical" used in many household cleaners and such as goo-gone, and detergent type molecules. The newer removers which are intended for use on plastic nails ( acetone would not be good for this !) are mainly limonene instead. Actually it might not damage it, just that without knowing exactly what is in it ( and some ingredients might be proprietory and not listed, and know the effects of each chemical such as limonene residue, one is taking a chance, whereas the chemistry of pure acetone is better known and documented. Some even feel acetone is not safe, but the chemistry indicates no effect on inorganic material such as metal ( EXCEPT possibly in the presence of light, air, and moisture, acetone can affect metal like an acid over a period of 12 or more hours ) I think RLM first brought that to my attention. Most chemists would say use a dark glass container, pure acetone for less than a couple of hrs, you should be good. Jim[/QUOTE]
