<p>[QUOTE=&quot;BadThad, post: 756522, member: 17261&quot;]One thing not mentioned here....collectors usually just conserve PVC damage by soaking in acetone. This will not completely cure the problem. The first step should be a soak in VERY mildly alkaline conditions to neutralize the hydrochloric acids. I recommend adding just a few specks of sodium bicarbonate (baking soda) to a small volume of distilled water and dissolving. Soak the coin in this prior to soaking in acetone.[/QUOTE]</p><p><br /></p>
