<p>[QUOTE="Oldhoopster, post: 2716834, member: 84179"]As a reminder, Acetone WILL NOT remove tarnish or toning. It will only remove dirt and other organic material stuck to the coin, like residue from PVC degradation, tape residue, etc. Toning is caused by a chemical reaction with the surface metal of the coin (simplified explanation). Acetone will not do anything to this.[/QUOTE]</p><p><br /></p>
