<p>[QUOTE=&quot;BadThad, post: 2301852, member: 17261&quot;]&quot;Acetone color&quot;? More likely due to using MS70. Acetone will NOT react with metal, plain and simple. I&#039;ve used acetone on THOUSANDS of copper coins and it has never turned any of my coins. One single exception is a copper token from the 60&#039;s that was covered with a semi-sticky, transparent residue. When I used acetone on it a haze formed (probably dehydration of the non-polar-type residue). A soak in xylene removed the residue and the haze.[/QUOTE]</p><p><br /></p>
