When cleaning a helmet, one must differentiate between internal and external cleaning. The helmet shell is best cleaned with a damp, soft cloth. No scratchy or hard objects should come into contact with the shell, otherwise scratches may occur. As far as internal cleaning is concerned, many riding helmets are now equipped with inlays. These can be easily removed thanks to integrated Velcro fasteners or several press studs, making them easier and more efficient to wash. Depending on the manufacturer's specifications, some can even be cleaned in the washing machine.
