<p>[QUOTE=&quot;CopperKing559, post: 1333191, member: 34940&quot;]Thanks for the replies. I was under the impression that acetone was damaging to coins. I&#039;ve been sorting copper from Zincoln&#039;s and come across many coins that need a quick wash. They are all circulated and I check them for rare ones, and after that I clean the ones that need it. Would it be alright to dump a 50 cents or so in some acetone and let them sit for a bit, possibly wipe them with a q tip and let dry? I don&#039;t want to damage the surface with a quick soak in acetone, so if it doesn&#039;t damage I&#039;ll probably switch from vinegar to acetone.</p><p><br /></p><p>I&#039;ve also read to rinse with distilled water, then again, I&#039;ve read not to. What would be the point of the rinse with water? If it&#039;s 100% acetone, won&#039;t it all evaporate with no residue?[/QUOTE]</p><p><br /></p>
