<p>[QUOTE=&quot;desertgem, post: 1483450, member: 15199&quot;]PVC contaimination&nbsp; leads to PVC damage which is corrosion. Once the metal is visibly corroded, it can&#039;t be reversed. Iyt may be disguised by toning, darkeners, or fillers,&nbsp; but it is still there. </p><p><br /></p><p>PVC contamination can be removed with acetone ( as per your other thread), PVC damage, if it is still microscopic level can be helped with the Verdi-Care type of products from BadThad ( I like his products, they do as he claims, but often people expect more ) pitting PVC corrosion is there for good. </p><p><br /></p><p>Acetrone will remove the PVC softener chemicals from the coin and halt the activity, although regular moisture can attack that area more vigorously than the patina on the coin that hasn&#039;t had PVC damage. Acetone won&#039;t dissolve metal, so it won&#039;t increase corrosion. Verdicare can help protect it, but the key is the owner protecting it from environmental damage.</p><p><br /></p><p>On the shower curtain smell, I use to say this all of the time, but now notice that Walmart ( local supplier of many things chinese ) have shower curtains from China that says &quot;PVC Free&quot;&nbsp; and do not smell like PVC <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie3" alt=":(" unselectable="on" unselectable="on" /></p><p><br /></p><p>Jim[/QUOTE]</p><p><br /></p>
