<p>[QUOTE=&quot;lkeigwin, post: 1190160, member: 30400&quot;]&quot;Don&#039;t clean coins&quot; is rarely bad advice. But let&#039;s face it, professionals do it, TPG&#039;s do it, experienced collectors do it.</p><p><br /></p><p>But they don&#039;t use aluminum foil or lemon juice or vinegar or any home remedy. They don&#039;t scrub them, or wipe them. They have experience and knowledge and a good idea of what can be done to rescue a coin. Problem is 95% of collectors don&#039;t know and they end up damaging coins. That is why we tell everyone &quot;don&#039;t clean coins&quot;.</p><p><br /></p><p>- Acetone is safe and removes organic crud (oil, grease, paint, PVC).</p><p>- eZest or Jeweluster (same thing) is a dip that will remove tarnish. Silver coins will turn white. It may not remove stains or other matter that has bonded to the surface. If a coin is dipped too long, or too often, it will lose its luster and appear lifeless. Nothing can restore it.</p><p>- CoinCare is a preservative that will not harm coins and may help with simple dirt and grime. Gently apply with a q-tip.</p><p>- Lengthy oil soaks can help soften crud but the coin usually needs a little help afterwards with a rose thorn or a gentle q-tip. Lots of disagreement over the type of oil. Mineral oil doesn&#039;t go rancid but others swear by olive oil.</p><p>- I&#039;m not fond of MS70 but some folks use it to treat spots. It&#039;s not meant as a dip.</p><p>- Blue Ribbon is hard to find but cleans grime and dirt nicely. The PCGS sniffer barks at it.</p><p>- Verdicare treats verdigris and is pretty good at it. The sniffer barsk at this too, allegedly.</p><p><br /></p><p>Beware of using anything with red copper. Results vary.</p><p><br /></p><p>Back to &quot;don&#039;t clean coins&quot;...if you want to learn safe conservation, practice on junk. The OP&#039;s coin, if worth no more than melt, isn&#039;t a bad coin to experiment with.</p><p>Lance.[/QUOTE]</p><p><br /></p>
