[QUOTE="-jeffB, post: 2359274, member: 27832"]Good idea, for two reasons: 1) Less likely to break if you knock it down, splattering flammable acetone everywhere. 2) There's an ongoing debate here about whether acetone can damage copper coins. The paper that's usually cited by the "yes" side studied surfaces exposed to light; if there's anything to it, keeping your acetone in the dark while soaking things would help avoid the problem. I'd be nervous about putting acetone in a plastic container. I know it's supposed to be compatible with polyethylene and polypropylene, but I'd still worry about it dragging out plasticizers that could react with your coin surfaces.[/QUOTE]
