What to Do When the Windshield Wipers Leave a Blurry Streak?

Specific causes and solutions for blurry streaks after windshield wiper use: 1. If the washer fluid reservoir is filled with water, it should be replaced with windshield washer fluid, which has cleaning properties. 2. Dirt on the wiper blades can cause this issue. Lift the wiper arm and clean the blades thoroughly. 3. Prolonged use may cause the wiper blades to age and lose proper contact with the windshield due to curvature mismatch. Lift the wiper arm and bend the blade several times to reshape it. 4. Check if the wiper rubber has hardened or developed uneven surfaces. Sanding the rubber strip smooth can restore normal wiper function.
Last time I was driving on the highway during a heavy rainstorm, the windshield wipers actually made visibility worse after wiping, which scared me so much that I immediately pulled over. After getting home, I checked and found a layer of oily film on the windshield, just like grease stains on a frying pan, seriously affecting visibility. I spent a long time scrubbing with diluted kitchen detergent but it didn’t work. Later, I specifically bought a glass oil film cleaner and used it with volcanic clay to finally clean it off. Also, pay attention to the wiper blades—when the rubber ages, it tends to leave water streaks on the glass. I usually replace them every six months. Now, I flush the wiper grooves with windshield washer fluid every quarter to prevent leaves and sand particles from jamming the blades. If you encounter this situation on the road, never force yourself to keep driving—it’s just too dangerous.
