We suggest you give your helmet a quick wipe with a soft cloth when you are done with a ride, especially after one in the rain. Even though our helmet is water-resistant, and the electronics are sealed, please do NOT take it to the shower to give it a wash.
Using a soft, damp cloth and rubbing the Matrix or Street shell gets rid of most of the dirt and grease.
To clean the straps, you can use a damp cloth. Please wring out the cloth, so most water is removed and then wipe the straps gently.
To clean your helmet padding, simply remove them from the helmet (they are attached with velcro) and hand-wash them with mild soap or laundry detergent, then line dry the padding instead of putting them in the dryer.
Some acids/oil can cause polycarbonate to become very brittle and crack, so please DO NOT use any chemicals to clean your helmet.
