Some wiper blades are not aerodynamic and can lift off at high speeds. This causes misswipes and can be dangerous.

Windshield contamination is a common cause for poor wiper performance even if the wipers are still in good shape. Some kinds of contamination, such as tree sap, can destroy the wiping element in a short time. We recommend cleaning the windshield regularly with car wash soap as regular dish soap or hand soap can be corrosive to car paint.
