If the head band pads become dirty, they can be wiped
clean with a dry cloth. If this is insufficient to clean the
pads, they may be cleaned with ethanol, but take care to
prevent any splashing onto the lens.
Dirt and dust can be removed from the control box by
wiping it clean with a dry cloth. If this is insufficient, you
can use a moistened cloth, but make sure that it is well
wrung to minimise the risk of getting water into the control
box.
