Hi Roger,
I tried to clean this Chanel caviar skin bag with the 'restorative cleaning' protocol of the A3 kit, starting with Prep 4.4, however these stains did not come off at all (please see pictures). I'm guessing it is some kind of color transfer from maybe clothes or other material. Could you tell me which products I need to get in addition to the products of the A3 kit to be able to remove these blackish marks?
Thank you!
Charlotte
