<p>[QUOTE=&quot;Marshall, post: 911298, member: 21705&quot;]I know the optimim is to not have a coin with verdigris, but when you do, I&#039;d like to know the best process for removing the verdigris ONLY and then removing any harmful chemical residue.</p><p><br /></p><p>I know I&#039;ve used a xylene based oil for dissolving petroleum soluble dirt and it was supposed to be inert and not harm the coin. I have also used Blue Ribbon as a protective coating from the myriad of chemicals in the air. I live in SE Texas near numerous chemical plants. Distilled water seems to leave the coins vulnerable to quick and harmful corrosion.</p><p><br /></p><p>I&#039;ve heard others talk about quick dips to remove the verdigris followed by a rinse in distilled water and acetone so the water doesn&#039;t form spots.</p><p><br /></p><p>If I had the money, I&#039;d get all my coins conserved, but I&#039;m with you on trying to preserve to coins under attack by whatever means causes the least harm.</p><p><br /></p><p>ps In reality, circulating coins get layers upon layers of protective human oils from handling though they harm the MS when they leave only single fingerprints. I tend to thing the marks are left by the unpreserved portions of the fingerprint rather than the oil from the fingerprint.[/QUOTE]</p><p><br /></p>
