No, as your bag is padded. Therefore, you cannot put it in the washing machine. You can, though, hand-wash it. First, try to wash it with lukewarm water. If the stains are not gone yet, add soap, or dishwashing liquid, or soft soap. Always use a soft cloth or a sponge or a small brush (a toothbrush works wonders ;-). However, do not use any aggressive cleaning detergents, such as benzene, ammonia, etc.
