Medela Pump in Style Advanced Shoulder Bag

Can you wash the carrying bag for a Medela Pump in Style breast pump?
I was just wondering... if I removed the pump motor and everything, do you think I could hand wash the bag itself in Woolite or something? I have the shoulder bag for the PIS Advanced, and I want to wash it because it smells like smoke from someone's house I left it at.
Anyone done this before?
I think you can. You can call or email Medela.
