We always recommend using a microfibre cloth to clean the exterior of your helmet. Simply use warm water to gently wipe away any dirt, don't use any cleaning products, cleaning solutions can damage your helmet.

Interal sun shields & visors typically have some sort of protective coating so it's the same as the helmet, use warm water only. No sprays or chemicals. To get rid of any water marks you can just use a clean & dry microfibre cloth to completely remove thems. We always recommend removing the visor before cleaning.
