The interior and exterior condition of the helmet must be examined before and after each use. The exterior shell can be cleaned with clear water. The chin straps can be cleaned with pure water and mild soap. 1 Do not use any chemically aggressive or corrosive detergents. Store the helmet away from light, in a cool and well-ventilated place. 2 UV rays (sunlight) or high temperatures (3 if the helmet is left in the car in summer, for example) can have an adverse effect on the product and, consequently, on its protective capacity as well. 3 A backpack, bag or other appropriate container is recommended for transportation. In normal usage (without the impact of rockslides, falls etc.), it is recommended that the helmet be changed every three years.
