<p>[QUOTE=&quot;desertgem, post: 2206704, member: 15199&quot;]Acetone can not dissolve or react with metals without a user imposing environmental/chemical&nbsp; situations far from normal coin environments. However, it can produce haze appearance if rinsing with fresh acetone is not done and dissolved materials redeposit on the surface ( very apparent with proofs ~rinse well with fresh acetone and hold vertical by the edge until air dry ), AND it can remove any previous &#039;toning&#039; that is not a natural metal reactant, such as smoke ( cigars, etc), artists colors, tints, etc. Then the underlying color appears different and the owner thinks the acetone changed the color, when it just removed the fake coloration. Use only 99% or better acetone , not that labeled acetone for fingernails. I use verdicare products also and the original formulation, I used acetone after removing verdegris, but when Thad went to his react formula, I stopped. Do not use water rinse after acetone as it just sets the coin up for damage. The acetone evaporates 100%, carrying any excess water with it. All my&nbsp; opinion from extensive use, your mileage may vary. Start with some pocket change for practice.[/QUOTE]</p><p><br /></p>
