I looked at Verdi care ads, and ironically they don't show photos. The description sounds more like a coating to the coin than a cleaner.
I haven't experienced Acetone removing any thing that has effected the surface of the coin. If it's an organic coating of some sort Acetone should remove it, but nothing else.
Just my experience.
Verdi Care is like #35.00 for an ounce ? For that price I would like to see some photos.
