<p>[QUOTE=&quot;Kentucky, post: 8338441, member: 33176&quot;]Concerning acetone and what it will and will not do.&nbsp; Acetone will not harm the metal of your coin.&nbsp; It is not corrosive, it is just a solvent like water.&nbsp; It will remove many organic contaminants from the coin&#039;s surface.&nbsp; This can be good, to reveal detail, and bad, to reveal scratches and dings.&nbsp; Lab grade acetone is quite expensive and not necessary.&nbsp; Don&#039;t use fingernail polish remover because they may contain perfumes and lubricants to keep ladies&#039; skin from drying out.&nbsp; Hardware stores sell pure acetone and that is sufficient.&nbsp; Get some and try it on a &quot;test&quot; coin that has little value.&nbsp; Let us see how it did.&nbsp; If the stuff on the surface isn&#039;t organic, acetone will do nothing.&nbsp; Some organic material is better removed by xylene (many hardware stores have this too).[/QUOTE]</p><p><br /></p>
