Blade inspection

Contamination of the windshield or wiper blades with foreign substances may reduce the effectiveness of the windshield wipers.

Common sources of contamination are insects, tree sap, and hot wax treatments used by some commercial car washes. If the blades are not wiping properly, clean both the window and the blades with glass cleaner or mild detergent, and rinse thoroughly with clean water. Replace blades as needed.

To prevent damage to the wiper blades, arms, or other components, do not:

  • Use gasoline, kerosene, paint thinner, or other solvents on or near them.

  • Attempt to move the wipers manually.
