Hello. I was looking at my Cambon Pouchette today and noticed the silver hardware where the straps are attached to are starting to turn. They look a bit rusted. I immediately checked my Cambon Tote, but that was fine, looks brand new, and I use this one very often. The Pouchette I hardly use. I don't get it. Has anyone else had this issue? If so, what did you do to get it back to looking somewhat new again. Pls let me know.
