Replacement of windshield wiper
blades
Grease, wax, insects, or other material on the wind-
shield or the wiper blade results in jerky wiper
operation and streaking on the glass. If you cannot
remove the streaks after operating the windshield
washer or if the wiper operation is jerky, clean the
outer surface of the windshield (or rear window) and
the wiper blades using a sponge or soft cloth with a
neutral detergent or mild-abrasive cleaner. After
cleaning, rinse the windshield and wiper blades with
clean water. The windshield is clean if beads do not
form when you rinse the windshield with water.
CAUTION
Do not clean the wiper blades with gasoline or
a solvent, such as paint thinner or benzene.
This will cause deterioration of the wiper
blades.
If you cannot eliminate the streaking even after fol-
lowing this method, replace the wiper blades using
the following procedures:
1. Raise the wiper arm off the windshield.
