What to Do When the Windshield Is Blurry and Doesn't Clean Properly?
4 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.
I love DIY car repairs. If the windshield isn’t being cleaned properly, start by checking the cause. Remove the wiper blades to inspect for wear—if they’re scratched or hardened, toss them and replace with new ones, making sure to align and secure them properly in the slots. A blurry windshield is often caused by oil film buildup; mixing white vinegar with warm water and wiping the surface works well, but be careful not to damage the paint. Also, check the washer fluid and ensure the nozzles aren’t clogged, so the liquid sprays evenly. When washing the car, use a soft cloth to clean hard-to-reach areas on the glass to prevent long-term blurring. Keep a bucket and an old towel handy for emergencies. Replacing parts yourself saves money and is quick, avoiding unnecessary shop expenses while also learning new skills.
Never force driving when the windshield is blurry - safety comes first. I'll pull over as soon as possible, find a wet cloth to clean the wiper blades and glass for temporary treatment before trying again. Replace old or stiff wipers immediately - don't delay. During car washes, thoroughly clean the front windshield to prevent dirt buildup. Keep the washer fluid reservoir filled with quality fluid to avoid dry wiping damage. Poor visibility reduces reaction time and increases accident risks, so develop regular inspection habits. If problems persist, visit a repair shop immediately for professional assistance.
