I'm way out over my skis on this topic, but I've read it with interest, and I do collect leather bound books, sporting arms, and I own a pair of elephant tusks (pre-CITES). I have always read other than Ren Wax, not to use anything on ivory. Now, reading about the maintenance of ivory scales here, I'm wondering if that's correct, or if ivory that is being handled a lot is in a different category?
