What to Do When the Windshield Is Blurry and Doesn't Clean Properly?
2 Answers
Solutions for a blurry windshield that doesn't clean properly are as follows: 1. Check for dust and small stones between the windshield and wiper blades: If present, clean them promptly, and also clean the grooves on both sides of the wiper rubber. 2. Check if the wiper components are loose: If looseness is found, use needle-nose pliers to tighten the gaps at each joint and the rubber blade holder. This not only effectively reduces noise but also improves the wiper's cleaning performance. 3. Check for material aging: Aging wiper blades may not clean properly. In this case, use fine sandpaper or a specialized repair tool to polish the rubber blade, rinse off dirt with clean water, and finally apply lubricant for maintenance. If the wear is severe, consider replacing the rubber blade or the entire wiper. 4. Wiper arm issue: Normally, the wiper should form a right angle with the windshield. If the angle is misaligned, cleaning efficiency decreases. Use a wrench to adjust the angle back to the correct position.
After years of driving, when the windshield gets blurry, I usually first check if the wiper blades are aged or cracked. The rubber on wiper blades hardens and loses elasticity over time, leading to poor wiping performance. Replacing new wiper blades is simple—just buy a matching model online and install them yourself; it costs only a few dozen yuan. The glass surface might accumulate oil film or dirt, especially in cities with heavy dust. Use a dedicated glass cleaner during car washes, spraying and wiping several times to remove grease. Additionally, an empty or low-quality washer fluid reservoir can also cause blurriness—filling it with high-quality fluid helps. Try to avoid parking under trees or in areas with many birds to reduce dirt buildup. Blurry windshields limit driving visibility, especially on rainy days, increasing the risk of accidents. Regular maintenance of the wiper system is essential to ensure safe driving.
