Has any one ever had the leather around the top zipper start to flake off. I received a vintage Chanel from my mother in law. It had not been kept in a dust bag and was very dusty. I tried to clean it with a sort cloth moistened with a little water. Since then, the leather in that area is literally flaking off. I don't know if it was very dry and I rubbed I little to aggressive trying to get in the creases. The bag has a top zipper. How do I stop the flaking. I hope I haven't ruined the whole bag. I feel sick about it. Any help will be so appreciated. Thank you. (Obviously, this is my first Chanel bag)
