<p>[QUOTE=&quot;BadThad, post: 1820683, member: 17261&quot;]I&#039;ve had this happen a couple times, both times acetone kind of hazed the surface. I ran the coins though water and xylene after the acetone, then hit them with acetone again and the &quot;problem&quot; went away. Both times is was due to an invisible surface residue and not a reaction between acetone and copper.[/QUOTE]</p><p><br /></p>
