<p>[QUOTE=&quot;GDJMSP, post: 2253097, member: 112&quot;]Fair enough Thad, you&#039;re the chemist not me. I&#039;ve just never seen any, on coins anyway, that wasn&#039;t green. On copper pipes, yeah it&#039;s quite common.</p><p><br /></p><p><br /></p><p><br /></p><p>The stuff works, there is no question of that. I&#039;ve tested it myself and so have many others on this forum. But Thad&#039;s own data sheet says that on coins with heavy verdigris it may not remove all of it. In other words it&#039;s a question of severity, the more severe the verdigris, the less likely the product is to remove all of it. But it will always remove some, or even most of it.</p><p><br /></p><p>But users of the product must understand, even if it removes all of the verdigris from a coin, the product does absolutely nothing to repair or lessen the damage done to the coin by the verdigris prior to its removal. All it does is take away the powdery residue of the corrosion, leaving behind any pitting on the surface of the coin. And there IS going to be pitting for that is what corrosion does.[/QUOTE]</p><p><br /></p>
