<p>[QUOTE=&quot;GDJMSP, post: 2010306, member: 112&quot;]Read here - <a href="https://www.cointalk.com/threads/proper-acetone-procedure.193708/" class="internalLink ProxyLink" data-proxy-href="https://www.cointalk.com/threads/proper-acetone-procedure.193708/">https://www.cointalk.com/threads/proper-acetone-procedure.193708/</a></p><p><br /></p><p>As for the disagreement regarding acetone and copper, well let&#039;s just say it&#039;s one of those things that unless you have experienced it yourself, many tend to say it&#039;s not an issue or that it doesn&#039;t happen. In other words they believe there is no problem with using acetone on copper.</p><p><br /></p><p>That said, I am one of those who has experienced it (a problem) himself, and seen and read of similar results in the experiences of others over a period of many years. So what exactly is the problem when using acetone on copper ? The problem is that acetone when used on copper can sometimes cause the coin to tone weird colors after the fact. It doesn&#039;t happen always, but it does happen sometimes.</p><p><br /></p><p>Now people try and come up with all sorts of explanations for that &quot;sometimes&quot; in order to confirm their belief that there is no problem with using acetone on copper. They want to believe they are right because it has never happened to them, even though they have used acetone on copper many times.</p><p><br /></p><p>There&#039;s only one problem with that line of thinking. I&#039;ve never actually seen a meteorite strike the earth, and neither have most people, but that doesn&#039;t mean it doesn&#039;t happen.</p><p><br /></p><p>So what to do ?
