Grease, wax, insects, or other material on the windshield 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.

- Do not clean the wiper blades with gasoline or a solvent, such as paint thinner or benzine. This will cause deterioration of the wiper blades.

- When returning the raised wiper arms to the original positions, carefully return the wiper arms on the windshield while supporting them with your hands. You should not return the wiper arms to the windshield only by the return spring. Otherwise, the wiper arms may be deformed and/ or the windshield surface may be scratched.

If you cannot eliminate the streaking even after following this method, replace the wiper blades using the following procedures.

• Windshield wiper blade assembly
• Windshield wiper blade rubber
• Rear window wiper blade assembly
• Rear window wiper blade rubber
