<p>[QUOTE="illini420, post: 1915654, member: 19423"]Me too... I just conserved a silver Chinese coin recently that had some PVC residue. I soaked in acetone first for around 10 minutes which loosened up the PVC. Then a quick dip in the E-Z-est (at half strength mixed with water so I can better control it). Then a very good rinse under tap water. The last step for me is another dip in a clean batch of acetone where the coin is swished around well in the acetone, then I simply set the coin on a paper towel and let any remaining acetone evaporate. I flip the coin over on the paper towel after 30 seconds to a minute so the other side gets plenty of air to evaporate too. I'll then inspect the coin for any remaining residue... if any remains then the process is repeated... if there is no residue, then the work is done.[/QUOTE]</p><p><br /></p>
