I hardly ever use my Damier Alma yet I've somehow managed to leave a water stain on the interior red lining! I'm usually extremely careful with my bags but I think I might have put a COLD bottle of water inside my bag and the condensation from the cold bottle left a water mark. (it looks like a wriggly line) Is there anything I can do to remove this mark? What is the bottom of the Alma made of? I had thought the bottom exterior is leather and the interior red lining is just cloth? Not sure why the stain won't go away as it seems to be only water stains! Thanks for any help!
