What Causes Blurriness After Using Windshield Wipers?
3 Answers
Blurriness after using windshield wipers occurs because the wipers fail to completely clear away water. When this happens, you should replace the wipers with new ones, which will resolve the issue. Windshield wipers are made of rubber, and rubber products can degrade over time with use. When the rubber on the wipers deteriorates, it no longer adheres properly to the windshield, preventing the wipers from effectively clearing water. If the water isn't fully removed, it can cause the windshield to appear blurry after wiping. There is no fixed lifespan for windshield wipers, but they should be replaced when they no longer clean effectively or produce unusual noises during operation.
I've been driving for over a decade and have encountered many instances where the windshield wipers leave streaks. The main reasons are usually aging and deformation of the wiper blades, or hardened rubber strips that don't wipe cleanly. High summer temperatures accelerate rubber deterioration, while winter ice also affects performance. Another common issue is oily film residue on the windshield, formed by accumulated exhaust fumes and dust in urban driving that ordinary washing can't remove. I recommend regularly checking if the wiper blades are sticky or cracked—replacing them annually is low-cost but highly effective. For cleaning the glass, using a degreaser or alcohol wipes works quickly. If you notice line-shaped shadows in the blurred areas, it might be due to uneven pressure from the wiper arm, which can be adjusted at a repair shop. Remember not to operate the wipers on dry glass to avoid damaging the rubber strips. Safety comes first in rainy weather, and clear visibility helps prevent rear-end collisions.
I just got my driver's license last month. During heavy rain, I was startled to find the view still blurry after using the wipers. A friend explained this is common—old wiper blades lose elasticity, or the windshield accumulates bird droppings and oil stains if not cleaned promptly. Dust on the window before rain can also cause this. I learned wiping the glass and wiper edges with a slightly damp cloth helps, but replacing the blades works best. Buying wipers online for just tens of yuan and following tutorials to replace them myself is easy and worry-free. Parking away from direct sunlight extends rubber lifespan. If visibility gets blurry while driving, stay calm, slow down, and turn on hazard lights for safety. Small preventive habits avoid big risks—maintenance costs little but pays off well.
