Like COHgirl mentions - I've had good luck by emptying the bag, pulling the lining out (inside out) and using lukewarm water and a mild detergent (I like Ivory dish soap, bcz it's clear) on a washcloth, then gently scrub the lining where soiled. To rinse the soap out of the lining, just rinse out washcloth and re-rub the lining until clear. I've literally had the entire lining completely wet; just allow to air dry with the lining still outside the bag. When it's dry, it's like new again! Just be careful if it's a delicate leather.
