Vision is one of the most important things that determines safe driving. If our windshields are the eyes of our cars, then the wipers are the eyelids of our cars. When they get full of junk, dirty or damaged, they can’t do their job of keeping our windshields clean and our field of vision the best it can be. If your wipers jump across your windshield rather than gliding smoothly, they probably need to be cleaned. Spray a rag with wiper fluid and clean the blades and your windshield. If this doesn’t solve the problem, the blades or the wipers themselves may need to be replaced. Check your wiper blades regularly for any cracks, splits or tears and plan on changing them every six months in average climates and more often in very wet or extreme climates.
