What are the reasons why wipers cannot clean the windshield properly?
3 Answers
Wipers may not clean the windshield properly due to excessive dirt, misalignment creating blind spots, or aging and hardening of the wipers. Detailed knowledge and solutions regarding wipers are as follows: Wipers: Wipers are devices used to remove raindrops and dust attached to the vehicle's windshield, improving the driver's visibility and enhancing driving safety. By law, almost all vehicles are equipped with wipers; rear windows of hatchbacks and SUVs also have wipers. In addition to cars, other means of transportation such as trains and trams are also equipped with wipers. Solutions: Purchase appropriate cleaning agents and regularly use them to remove dirt from the wipers and residual grease on the windshield, ensuring the wipers can clean effectively and maintain clear visibility; replace the wipers when necessary to prevent aging and hardening due to weather conditions, which may impair their functionality.
I've been driving for over a decade, and it's quite common for wipers to not clean the windshield properly. The main reason is aging wiper blades – the rubber hardens or cracks, leaving water streaks or lines when wiping. Oil film or dirt on the glass, like tree sap, insect remains, or dust that wasn't cleaned properly during car washing, can also affect wiping performance. If the wiper arm is bent or the spring is loose, uneven pressure prevents the blade from pressing tightly. Winter freezing makes it worse when wipers can't move. I recommend checking wiper blades every six months, cleaning the windshield with specialized cleaners, and ensuring proper wiper installation. These small details can prevent blurred vision in rainy conditions and improve driving safety – don't wait until an accident happens to regret it.
As an automotive enthusiast, I've identified several key factors affecting wiper performance. The primary issue is material degradation - rubber blades become brittle and lose elasticity when exposed to UV rays. Contaminants like oil or bug residue on windshields create a film that impedes wiping. Improper installation angles or insufficient wiper arm tension also cause problems. I recommend regular windshield cleaning with isopropyl alcohol and switching to more durable silicone wiper blades. Always check for wiper arm deformation and adjust pressure when necessary. These simple maintenance steps can significantly improve driving experience and prevent dangerous situations during heavy rain.
