Clean the rubber edges of the wiper blades and the
windshield periodically with a sponge or soft cloth
and a mild nonabrasive cleaner. This will remove
accumulations of salt or road film.
Operation of the wipers on dry glass for long
periods may cause deterioration of the wiper
blades. Always use washer fluid when using the
wipers to remove salt or dirt from a dry windshield.
Avoid using the wiper blades to remove frost or ice
from the windshield. Keep the blade rubber out of
contact with petroleum products such as engine
oil, gasoline, etc.
NOTE:
Life expectancy of wiper blades varies depending
on geographical area and frequency of use. Poor
performance of blades may be present with chat-
tering, marks, water lines or wet spots. If any of
these conditions are present, clean the wiper
blades or replace as necessary.
The wiper blades and wiper arms should be
inspected periodically, not just when wiper
performance problems are experienced. This
inspection should include the following points:
Wear or uneven edges

Foreign material

Hardening or cracking

Deformation or fatigue

If a wiper blade or wiper arm is damaged, replace
the affected wiper arm or blade with a new unit. Do
not attempt to repair a wiper arm or blade that is
damaged.
