Note:
After intensive cleaning, riding in the rain or long journeys in cold
weather, the anti-fog coating takes a little time to become
completely effective again. During this time, the coating is unable
to absorb much or any moisture from your breath. You can
accelerate recovery of the coating's anti-fog property by placing
the helmet in a dry, well-ventilated place.
Note:
Only use tepid water (<20° C) for cleaning. Never on any account
clean the outer visor or sun visor with petrol, solvent or a window
or glass cleaner or other alcohol-containing cleaning agents.
Note:
Never apply anti-fog gel, spray or similar substances to the
active anti-fog coating. This can cause undesirable reactions and
even irreparable damage to the coating.
Note:
The active anti-fog coating is subject to an ageing process, the
rate of which depends on the intensity of use and the
environmental conditions. For your own safety, we recommend
replacing the visor shield or sun visor if the anti-fog effect starts
to deteriorate significantly.
Note:
The active anti-fog coating will also absorb chemical substances
such as solvents and can be damaged by them. Therefore, avoid
storing the visor in the vicinity of aggressive substances such as
motor fuels or solvents.

Note:
Even moist lens cloths are often unsuitable for cleaning the visor
– despite recommendations to the contrary – since the
substances they contain are incompatible with the anti-scratch
and anti-fog coating. Avoid using these cloths.
Note:
Do not soak the visor in water (i.e. to soften heavy dirt) as this
can significantly reduce the surface hardness and thus the
resistance of the anti-fog coating.
Note:
Avoid closing the visor fully when the helmet is not in use
(especially in storage) since any moisture inside the helmet
cannot escape and will be absorbed by the anti-fog coating to a
greater extent than normal. This can reduce the service life of
the coating. The best method is to lock the visor open in the 2nd
locking position above the town-riding position.
Note:
Never attach labels, adhesive tape or stickers to the visor or sun
visor.
Tip:
A milky coating that may occur after a long period of non-use
(through reaction of the active anti-fog coating with the
environment) is most easily removed with a dry microfibre cloth.
Tip:
Stubborn dirt on the outer surface of the visor (e.g. dried-on
insect remains) can be easily removed by covering the closed
visor with a moist to wet cloth and allowing the dirt to soften for
around 1/2 to 1 hour.
