Clean the outside of the windshield with glass cleaner.
Clean the rubber blades using a lint free cloth or paper towel soaked with windshield washer fluid or a mild detergent. Wash the windshield thoroughly when cleaning the blades. Bugs, road grime, sap, and a buildup of vehicle wash/wax treatments may cause wiper streaking. Replace the wiper blades if they are worn or damaged.
Wipers can be damaged by: - Extreme dusty conditions.
- Sand and salt.
- Heat and sun.
- Snow and ice, without proper removal.
