it's my first time purchasing a "branded" purse (i usually spend my money on jeans) and i bought a Coach Signature Demi Pouch in Brass/Khaki/White. It was previously loved, in pretty good condition but there are some blue smudges on the white leather. Is there some sort of cleaner i can use? or if I bring it to the outlet, would they clean it for me? apart from that, the demi is perrrrfect! I love it!
