<p>[QUOTE=&quot;Oliver Newton, post: 2781804, member: 88390&quot;]I have a really strange issue I need advice with.&nbsp; I had some of my coin collection loose in a small box temporarily as I did some home renovations.&nbsp; I had the box on a shelf where I also had a container of car radiator fluid (stupid I know, but it was temporary and they weren&#039;t near each other).&nbsp; Well at some point the rad fluid container cracked and the fluid spread across the shelf and my box of coins soaked it up.&nbsp; </p><p><br /></p><p>Here&#039;s the issue.&nbsp; Most of my copper tokens from the 1800&#039;s have now got a sticky green tint to them.&nbsp; My silver coins seem to be ok.&nbsp; I was wondering if you know any safe way to maybe take the green tint away without ruining the original patina of the coin, or doing as little damage as possible?&nbsp; Is there something I could soak them in over a period of time that will draw it out?&nbsp; I&#039;ve been a collector for years and I know you should almost never clean an old coin, I&#039;m just not sure what to do.</p><p><br /></p><p>Any advice would be amazing at this point.&nbsp; All I&#039;ve tried is gently rubbing them with a dry paper towel and some of the green is coming off, however also some of the patina on certain coins.&nbsp; I didn&#039;t want to try anything else until some more research was done.&nbsp; I&#039;ve been reading through some threads on this forum about cleaning coins in acetone, would that work here?&nbsp; Thanks![/QUOTE]</p><p><br /></p>
