I usually just spray some disinfectant deoderizer in my helmet once in a while but last spring I decided a good cleaning was in order and scrubbed it out with some rug doctor solution....Holy crap, Helmet smells like azz when I dug it out last night. What are you guys doing to clean your lids? Do some of you tear them down and clean them? If I dont get the smell outa here I will be selling a real nice used helmet
