I recently found sort of fingerprintish I guess stain, but it doesn't really look like one on my Chanel bag after only using it once. (And I took good care of it!! I mean, I wouldn't carry it if I knew I was going to be eating, and I never put it on the floor, I put it on my lap.) So, I don't know what I am going to do about. It's a pink evening bag, I'm not sure what the material's made of....guessing satin, but again, I'm not sure. I guess I'll just try to ignore the stain/mark and then when I get a bit more wear out of it, I'll send it in to a purse cleaner place.
