I've been driving for over 20 years and often encounter situations where the windshield remains blurry after using the wipers. Based on experience, there are several possible reasons. The main cause is the aging, hardening, or wear of the wiper blade rubber, especially with blades that have been used for two or three years and can no longer adhere tightly to the glass, leaving water streaks. Oil film buildup on the glass from exhaust fumes of vehicles ahead or roadside dust requires treatment with an oil film remover. Insufficient or poor-quality wiper fluid lacking cleaning additives also fails to remove dirt effectively. Loose wiper arms causing uneven pressure result in incomplete wiping. External factors like dried bird droppings or insect residue on the windshield are even harder to clean. Blurry visibility is dangerous and increases the risk of accidents during rainy nights, so regular inspection and maintenance are essential. I recommend checking the condition of wiper blades every season, replacing them annually, and cleaning the windshield with professional cleaners or a homemade vinegar-water mixture.
