geraldbergeron New Member Canada 27 Posts	Posted 02/01/2019 1:08 pm Well... SPP-OTTAWA, You were right . Some acetone and all disappeared . I will retain this method, although the surface of the coin seems slightly altered ( maybe too much acetone...). Gerald Report this Post to the Staff
ace_ftw Pillar of the Community Canada 1747 Posts	Posted 02/01/2019 2:32 pm No,Pure Acetone does not harm the coin, the issue was with whatever was on the coin, if it was acidic it could have harmed the surface. This is the only drawback of acetone cleaning, it will remove the gunk, but normally the coin under the gunk does not always look as nice as we hoped. Report this Post to the Staff
