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 remove any items from inside the bag, place your bag inside of a pillow case and put it in the washing machine. Set the washer to Cold, Gentle or Delicate Cycle then simply hang to dry.
