What Causes White Marks When Wipers Scrape the Windshield?
4 Answers
The reasons for white marks appearing when wipers scrape the windshield are as follows: 1. Precautions: Avoid unnecessarily scraping the windshield. When it's not very dirty, try to clean it with a towel. Use windshield washer fluid produced by reputable manufacturers in the spray bottle and avoid using tap water as much as possible. Small stones stuck in the wiper or rubber deterioration may cause the wiper to scrape the glass directly. 2. Damaged rubber strip: The primary cause is likely a damaged rubber strip. External dust and sand particles can damage the wiper rubber strip, leading to water streaks during wiping. The lifespan of a wiper is approximately 6 months to 1 year, but with proper maintenance, it can last longer. 3. Poor design: The wiper itself may be poorly designed. One solution is to extend the wiper arm behind the wiper shaft to reduce the scraping angle. Loose connections in the wiper linkage support section should be inspected. Wear at the hinge points of the wiper linkage, deformation of the linkage, or failure may require replacement.
White streaks left by the wipers on the windshield are mostly caused by issues with the rubber blades. Over time, they age and become gritty, leaving marks with each swipe, or the windshield may be contaminated with oil or resin, showing white lines when washed by rain. With years of driving experience, I've noticed that parking under trees or not drying the windshield properly after washing the car often leads to this. It's advisable to clean the windshield regularly, use glass cleaner with a tissue to wipe the edges of the wipers, and replace the wiper blades every six months. Safe driving requires clear visibility, so don't wait until it rains to panic. Also, remember that rubber blades tend to harden with significant temperature changes, so early maintenance can prevent potential hazards.
It's quite annoying when the wipers leave white streaks, which might be due to worn rubber blades or dirty glass with dust and oil stains. I've tried wiping the wipers and glass with a sponge soaked in soapy water, and it helps a lot. To avoid scratching the surface by dry wiping, spray some cleaning fluid before driving. Usually, park away from pollution sources like industrial areas, and when replacing wipers, choose good quality ones instead of going for the cheapest. Driving at high speed with blurry vision is really unsettling, so it's recommended to check them monthly for peace of mind.
Wiper blades leaving white streaks are often due to aging rubber or residue on the windshield. Maintaining clear visibility is crucial for safe driving. I've noticed that rubber becomes stiffer in cold temperatures, making it more prone to issues. Cleaning the windshield with alcohol wipes is simple yet effective. Regularly replace wiper blades—don't wait until nighttime driving is affected to take action.
