<p>[QUOTE=&quot;physics-fan3.14, post: 2487556, member: 19165&quot;][USER=24314]@Insider[/USER] , that is a lot of back and forth. I think you are missing the basic point of what I&#039;m saying: acetone will do no damage to the coin, will not affect the metallic compounds, will only remove organic contaminants that shouldn&#039;t have been there in the first place, and will be completely undetectable if done properly. </p><p><br /></p><p>Bear: if done properly, acetone will not damage your coin at all. You can leave it in as long as you like, because it will not affect the actual coin at all - only organic compounds on the surface. In actuality, you really don&#039;t need to leave it in the acetone for more than a few minutes, because it will dissolve the contaminants fairly quickly (in all except for the most extreme cases). For far more scientific explanation and information (and an example of a very extreme case), see my thread here: <a href="http://boards.collectors-society.com/ubbthreads.php?ubb=showflat&amp;Number=5536102#Post5536102" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://boards.collectors-society.com/ubbthreads.php?ubb=showflat&amp;Number=5536102#Post5536102" rel="nofollow">http://boards.collectors-society.com/ubbthreads.php?ubb=showflat&amp;Number=5536102#Post5536102</a>[/QUOTE]</p><p><br /></p>
