<p>[QUOTE=&quot;desertgem, post: 818998, member: 15199&quot;]Acetone has been often mentioned as a means to remove PVC plasticizers/infections, but it also can be used to remove any loosely bound molecular water from the corrosion process. It doesn&#039;t<b> remove</b> corrosion products, but it can <b>reduce</b> it&#039;s activity due to lessened water. Then putting it into a &quot;relatively air tight&quot; holder will basically stop the corrosion process IMO.</p><p><br /></p><p>But this is a coin I believe in corrosion process&nbsp; rather than toning, and although I can not point to any spot and guarantee pitting, I would strongly expect to find it.</p><p><br /></p><p>Jim[/QUOTE]</p><p><br /></p>
