Wiper Blade & Windshield Wiper Tips
Worn wiper blades are dangerous. Because 90% of your driving decisions are based on a clear, unobstructed view of the road, it's a critical safety concern that your BMW's wipers provide you with the cleanest windshield possible.

Ozone, airborne contaminants, oil, sunlight and dirt all act to weaken and reduce your wiper blade's ability to keep your view unobstructed. And exposure to sunlight and ozone cause the wiper blades to age, even if they're not used much.

Weather also plays a critical role in your windshield wiper blade's deterioration. Freezing temperatures make the rubber in your wiper blades hard and brittle, which increases their tendency to crack or tear. Hot weather warps the rubber and prevents the blade from wiping your windshield cleanly.

Heavy use is hard on the wipers because dust, abrasives, road grime and bug juice wear away the cutting edge of the blade needed to clean the windshield. Even road dirt acts like and abrasive to wear away the flat surface necessary for a good squeegee effect.

Rubber also deterioates over time. As blades age, they lose their flexibility and are less able to wipe cleanly. The may develop a permanent set or curvature, which prevents full contact with your windshield.
