Rain-X Expert Fit Conventional Windshield Wiper Blade C-21 - 860021

Wiper blades deteriorate due to many environmental factors including:Common Wiper Problems: Avoid these common problems and extend the life of your wiper blades by following these simple steps: Sun: Ultraviolet light and ozone deterioration Oil: Car waxes and exhaust hold rubber-deteriorating oil Airborne debris: Sand, mud and dust carried in the wind Moisture: Acid rain and salt water (in moist air both near the shore and inland) Streaking occurs when the rubber squeegee dries, hardens and cracks. It can also be caused by tree sap, road tar, and other foreign substances collected on either the glass or the blade. Skipping occurs when the blade develops a curvature from lack of use (e.g. left in the ‘parked position’ for an extended length of time). Wearing occurs with extensive use and is when the rubber edges are rounded instead of squared. Splitting is caused when the sun’s ultraviolet rays penetrate the rubber squeegee, causing it to breakdown and separate from the frame. Bent Refill Vertebra and Bent Frames cause inconsistent contact with the glass surface, creating streaking or skipping. Clean your windshield every time you fill your gas tank. Gently wipe the rubber squeegee with a damp paper towel to remove any loose dirt or oil. Never use your windshield wipers to de-ice your windshield. Instead, either use an ice scraper or use your defroster to melt snow and ice. Pull your wiper blades away from the windshield during winter months to prevent ice build-up on the rubber squeegee and to prevent them from sticking to the windshield.
