I noticed that my pink Coach Penelope patent leather slim wallet has a couple black stains on the back bottom half. I take GOOD CARE of my purses/wallets so I have absolutely no idea how it happened. The only idea that I think it could possibly be is I also carry a black leather camera case (by Coach)... Could they have rubbed against each other and caused it? They aren't pen marks and the shiny covering of the patent leather is still "shiny" over the black stains. I was wondering if anyone knew how to gid rid of the stains without damaging the wallet (obviously haha). I've tried mild soap and gently rubbing it off, but no luck. Do you think if I were to take it back to the store they would exchange it? It is my FAVORITE wallet so I really wish I could just clean it and keep it. Any help is greatly appreciated.
