I recently bought a new helmet, a Charles Owen GR8. I noticed that it smells really bad. I used to have a GPA that said I could clean it in the dishwasher and that totally helped. Im not sure if I can do that to any other helmets without ruining them. I have tried the Charles Owen helmet cleaner and deoderizer and it helps until I put it on my head again. Does anyone have any other deoderizing suggestions.
