hi everyone! after being introduced to this forum, i have recently become obsessed with the coach legacy ali in white. while the $498 price tag is a little over my budget for now, i found one on eBay for a very good deal. the only thing stopping me now is that there are blue stains on the back of the bag, possibly from a jean jacket in the rain? not sure, and the seller can't tell me either. i'm pretty sure the bag is authentic, so the only question that i have is if these stains can be removed. the seller claims that the bag "has been lovingly used and does have some normal signs of wear along with a series of faded blue marks on the back bottom corner, not noticible to anyone when wearing it!" and also to use mild soapy water when cleaning. i've attached pictures below: i've done a few searches to see if anyone else has had this problem before, but came up with nothing. any help at all will be very much appreciated! thank you!
