We would recommend just cleaning your bag with lukewarm water and some mild soap. The bags are not really meant to be cleaned, but naturally, some bags will get dirty along the way. We do know a few people who have successfully put their bag in the washer on a gentle program at 30 degrees Celsius (86 degrees Fahrenheit). However, we cannot guarantee the outcome. As the label in your bag says, "Do not wash. You dirty Douchebag"
