The best way to remove small spills or stains (inside or outside) is to rub the spot using a wet washcloth with a small amount of dish soap.
If there was a major accident inside or outside of the bag, don't worry. Simply hand wash it in your tub or sink and use a small amount of dish soap and a wash cloth. Be sure to remove any items from inside the bag, then simply hang to dry.
