I washed my on the coldest setting, and just used regular detergent, along with a spray on stain remover that I used to remove some stains from the previous owners without removing any colours. Also, its its a G series kirby, I wouldn't put the bag in the dryer. I hung mine over a rack in my house also to dry. If it was something like a Heritage II bag, you could just remove it from the hanger at the top, and throw it in the dryer. Washing it works great at getting rid of stains and odours !
