Hi everyone: I just made what was probably a big mistake. I wore my straw colored Kooba Natasha with dark jeans and got some blue marks on the back of the bag. So I got the Mr. Clean magic eraser and tried using that and unfortunately it left a water-type mark that is worse than the original stain! Fortunately it is not in a very conspicuous place but I would still like to try to remedy the situation if possible. Any suggestions? Perhaps I should just take it to a leather repair/ shoe repair type of place.
