blower, clean
the body surface using
a soft, clean cloth. After use at
the
seaside, lightly soak a soft, clean cloth
with water and wipe off salt that may
be on
the body surface. Then wipe the
body surface with a dry cloth. Do not
use benzene, thinner, or other organic
solvent.

10. When removing dust on the lens
surface, use a soft oil-free brush.
11. When removing stains or smudges
like fingerprints from
the lens surfaces,
wipe the lenses very gently with a
soft clean
cotton cloth. Use a small
quantity of pure alcohol (ethanol) or
lens cleaner available in stores to wipe
stubborn smudges, from the center
of the lens to the outside in a circular
motion. Do
not use anything hard as it
may scratch the lens surface. (Fig. 14)
