Clean the helmet (and sun visor, if applicable) only with water, neutral pH soap, and a soft, clean cloth, and leave it to dry naturally at room temperature. The inner lining should be washed by hand in cold water. If it is removable, it can be removed and washed by hand in cold water or in the washing machine (max. 30°C – 85°F). In no case use chemical detergents, solvents, petrol or abrasive powders as they are aggressive and could lower the structural resistence of the helmet and the visor. Never rub the lens when dry.
