substances these contain are often harmful to the visor surface.
Avoid using these cloths.
Attention:
Even when badly soiled, never soak the outer surface of the visor
in water, as this will severely reduce its surface hardening and thus
resistance.
Tip:
Stubborn soiling on the outside of the visor (e.g. dried insect
remains) can be easily removed by leaving the visor in its closed
position, covered by a slightly damp cloth for 1/2 to 1 hour and then
wiping off.
3. INNER LINING
To clean the interior lining, use a mild hand soap solution
(e.g. with an ordinary mild cleanser). Apply the cleanser using a moist
sponge or cloth by dabbing or rubbing lightly. Do not rinse the interior. Next,
remove the soap suds by pressing a dry absorbent cloth on the pads. Repeat
these steps with clean water. When drying the interior of the helmet, make
sure it is well ventilated.
4. FASTENING SYSTEM
The double-D-ring fastener is maintenance-free.
Warning:
Do not oil or grease the metal parts of the fastening system
