<p>[QUOTE=&quot;Just Carl, post: 285349, member: 4552&quot;]Note there is another post about Acetone presently. This subject comes up as much as the weather. And probably just as contraversial. As already noted cleaning is cleaning is cleaning. However, Acetone is basically so non metal reactive, it can be used with little to no ability to notice it. True it can be used to remove glues, tapes, gunk, etc. but usually will not remove any substance that has been chemically interactive with the metal of the coin itself. This means what the majority think is Vertigris, PVC, etc. In the vast, vast majority of times&nbsp; those are expressions used when the substance is unknown and people want to call it something. Coppper reacts with Oxygen and then with Moisture and Carbon Dioxide to form Copper Carbonate. And that is the green stuff people think is all those other things. Remember when any substance is removed from a coin that has been chemically bonded to that coin, that is CLEANING. </p><p>Coins should not be Cleaned. </p><p>If an Acetone dip is absolutely wanted, see the other post on Acetone.[/QUOTE]</p><p><br /></p>
