How Often Should I Change My Wiper Blades?

Replacing wiper bladesWipers should be changed when they no longer perform as expected, or no longer provide a high level of safety.

Worn wipers can cause a dangerous driving condition, but usually go undetected until we’re depending on them to ensure good visibility.

The industry recommended replacement interval for preventative maintenance is 6 months. Though improved technology can extend the average wiper life, environmental conditions can drastically shorten it. Therefore, we recommend a safety inspection every 3 months, or at the start of each season.

Environmental Impact     Over time, the rubber on wipers blades naturally dries out. In dry climates, this process is sped along by the aging effects of UV rays and heat. Dust, sand, and other contaminants can also be damaging to the rubber wiping edge. As the rubber dries and ages, the blade becomes stiff, at times even cracking or separating. An aged wiper blade will chatter, smear, streak, or skip across the windshield.

How Can I Extend the Life of My Wiper System?

Cleaning     Windshield contamination is a common cause for poor wiper performance even when the blades 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 soap and water or a household glass cleaner.

Cold Conditions     Anytime it is below freezing, make sure the wipers are not frozen down before turning them on. Carefully lift the wipers so as not to rip the blade or bend the wiper arm. Turning the wipers on before clearing snow or ice from the windshield could tax the wiper motor, strip the wiper arms, or blow the wiper fuse. If the wiper is frozen down hard and difficult to break free, turn on the windshield defrost to melt the ice first.
