Why is the windshield blurry after wiping with wipers?
2 Answers
Windshield wipers leave the glass blurry because they fail to completely clear away water, indicating that it's time to replace them. Wipers are made of rubber, and rubber products degrade over time with use. When the rubber on wipers ages, it can no longer form a complete seal against the windshield, resulting in incomplete water removal. Wipers, also known as windshield wipers, are devices designed to sweep away rain and dust from a vehicle's windshield, improving driver visibility and enhancing road safety. Due to legal requirements, almost all vehicles worldwide are equipped with wipers.
I've seen many cases of blurry wiper blades, mainly due to aging and hardening of the rubber strips, which lose elasticity and fail to clear rainwater effectively. Oil film on the windshield is also common, caused by urban exhaust fumes or roadside dust accumulating into a layer of grime, making it hard for rainwater to flow away. High summer temperatures accelerate rubber aging, while winter cold makes it stiff. When I encountered this issue, I first cleaned the glass with vinegar water or professional cleaner to remove grease; if that didn’t work, I checked the wiper blades—replacing them is cheap and easy to do yourself. Insufficient pressure from the wiper arm can worsen the problem, and if the spring is loose, it needs adjustment. Avoid using low-quality wiper fluid or tap water with impurities, as they leave watermarks. Blurry vision while driving in the rain can easily lead to accidents, so a simple weekly cleaning can help prevent it.
