[QUOTE="BadThad, post: 2336801, member: 17261"]Insider, I will try to answer some your questions: It will evaporate (mostly) and potentially redeposit the very thing you were trying to remove. Acetone is indeed much cheaper but verdigris salts are insoluble in acetone. I have not seen this occur at all, VC is an excellent lubricant and I have zero reports of this technique leaving scratches. I've used the towel method on hundreds of coins with no ill-effect. The soaking method is very gentle (as VC is). Stubbornly attached residue will generally not be removed - such residues will require physical action. On a final note, you can search for the forums, my ebay feedback and the internet for others experiences with VC. The tone of your post is quick to condemn but the data/information is out there. It's not just a bunch of "hype" as you imply. I too am a collector (and chemist) and I made the product for MYSELF. It worked so well I decided to share it with other collectors - but the motivation was my personal need to conserve my coins. Before VC, all the methods people suggested on the internet to remove verdigris were futile or damaged my coins, i.e. catsup, vinegar, drain cleaner, acetone, olive oil, etc. I've tried them all. IMO, they are all pure bunk and either damaged the coin or did nothing.[/QUOTE]
