or a liquid household glass cleaner
will remove normal tobacco smoke and dust films
on
interior glass.
Don’t use abrasive cleaners
on
glass, because they may
cause scratches. Avoid placing decals on the inside rear
window, since
they
may have
to
be scraped off later.
If abrasive cleaners are used
on
the inside of
the
rear
window, an electric defogger element may be damaged.
Any
temporary license should not be attached across
the defogger grid.
Cleaning the Outside
of
the Windshield,
Backglass and Wiper Blades
If
the windshield is
not
clear after using the windshield
washer, or
if
the wiper blade chatters when running,
wax, sap or other material may be
on
the blade
or windshield.
Clean the outside
of
the windshield with

The
Grime from
the
windshield will stick to
the
wiper blades
and affect their performance. Clean
the
blade by wiping
vigorously with
a
cloth soaked in full-strength windshield
washer solvent. Then rinse the blade with water.
Check the wiper blades and clean them as necessary;
replace blades that look worn.
Weatherstrips
Silicone grease on weatherstrips will make them last
longer, seal better, and
not
stick or squeak. Apply
silicone grease with
a
clean cloth at least every
six months. During very cold, damp weather
more frequent application may be required. (See
“Recommended Fluids and Lubricants”
in
the
Index.)
