When helmets get dirty or take on an unpleasant odor, they can’t be placed in the washing machine with the rest of the hockey gear. Airing out the hockey helmet after use, rather than leaving it in the gear bag, can help keep bacteria at bay. For a more thorough job, you’ll need soap or shampoo, water and some extra care.
Break out the Shampoo
One way to clean a helmet is to fill a basin or bathtub with warm water and a bit of mild liquid soap or no-tear shampoo. Using baby shampoo or something similar helps protect you in case some residue is left behind after cleaning and drips into your eyes. Dip a sponge in the water and use it to scrub the helmet, reaching into all the crevices and the plastic straps. Use a towel to remove excess water, and then leave it in a well-ventilated area to dry. To get rid of bacteria that resists an ordinary wash, regularly use a disinfectant spray or a diluted solution of bleach and water -- not more than 10 percent bleach to 90 percent water. Check the care tag before using the bleach to ensure it's not harmful to the helmet's lining.
