<p>[QUOTE=&quot;GDJMSP, post: 2702886, member: 112&quot;]My previous comments had nothing to do with Verdi-Care, but rather with the importance of being able to identify what the &quot;green&quot; is. But since it came up, yeah Verdi-Care is a good product, I recommend it for its intended use of removing verdigris.</p><p><br /></p><p>As for the green, PVC contamination is far and away the most common. But it is important to note that PVC residue can be many colors, green is only one of them. It can also be almost invisible, clear; or it can be yellowish, brown, black, and even white at times. And for that you need a different product, acetone, to get it off. </p><p><br /></p><p>It&#039;s also worthy of note that there have been numerous cases of a coin having &quot;something&quot; green on it, but it wasn&#039;t verdigris, toning, or PVC residue. What it was I could not tell you, merely that it was none of them. </p><p><br /></p><p>Keep in mind, there basically 5 things that can be used to safely remove contaminants from the surface of a coin, and each one of them has specific uses. Meaning it&#039;ll work on this, but it won&#039;t work on that. Or put another way, you should only use this product to remove that problem. They are:</p><p>1 - distilled water</p><p>2 - acetone</p><p>3 - xylene</p><p>4 - Verdi-Care</p><p>5 - coin dip, and this one, it can be used safely only when it&#039;s used correctly. Use it incorrectly and you will forever damage the coin.[/QUOTE]</p><p><br /></p>
