Armor All is best! Sterling dries the chip out. You should see how many very dried chips I had to bring back to life with Armor All Protectant recently in a collection I was cleaning. Older hat and cane, C&J chips, the stamps wore off easy and can clean off easy. Best to leave those to someone like me who has cleaned a lot of chips- and no matter how much you try not to touch that stamp little bits can get taken off so leave old Christy and Jones hot stamps alone.
