Shell
For safe and gentle cleaning, use a plastic cleaner and/or wax to clean and polish the helmet shell, but not on the ventilation slider and other plastic parts. Do not use polishes on helmets with matte finish paintwork. For these helmets, use a mild detergent and water for cleaning.

Plastic Parts (Shield/Ventilation)
All plastic parts are susceptible to agents containing solvents (including any petrochemicals). These can be absorbed by the plastic material and cause its slow deterioration and increase the risk of breaking. Acid or alkali-based corrosive cleaning agents (as well as window cleaners) are equally unsuitable. For this reason, we recommend using only water and/or a mild, neutral cleaning agent. Heavily soiled areas can be gently cleaned using a soft toothbrush or a cotton swab. The shield and any other parts that can be removed should be removed for cleaning.

Interior Comfort Liner
All removable parts of the interior comfort liner should be removed and washed by hand or in a washing machine at 86° F using a washing bag and a neutral cleaning agent. Fixed padding should be wiped with a damp cloth, again using only a neutral cleaning agent. Antibacterial detergents have proven useful in removing smells.

EPS Liner
EPS is neither solvent nor heat-proof. The impact absorption liner must be treated with particular care during cleaning. As in all other cases, the EPS liner should be cleaned using only a damp cloth to avoid scratches or indentations.

Helmet Replacement
Ultimately, the useful service life of a safety helmet is dependent on the intensity and frequency of its use. Helmet replacement is recommended even if only one of the under-mentioned points applies:

• The helmet was subjected to an impact.
• The comfort padding or the retention system has become loose due to heavy use or display signs of deterioration. Test: with the retention system fastened, the helmet turns to the side when you gently shake your head.
• The EPS liner has come away from the helmet shell.
• The EPS liner shows signs of wear and is beginning to break up, or if it has been exposed to heat or a solvent and has melted. There are indentations in the EPS liner, and/or white scratches can be seen on surfaces with black paint.
• Even if none of these is applied, GLX recommends replacement 5 years after it's first purchased at retail.
