What to Do When There's a Water Streak After Wiper Wiping?
2 Answers
The reasons for a water streak after wiper wiping are as follows: 1. Wiper: If the new wiper is of poor quality, their rubber is often rough. Not only will there be water streaks (not wiping cleanly), but it may also be accompanied by a "squeaking" noise. In this case, you can use sandpaper to smooth it out. Another issue could be uneven force distribution, causing the wiper to not wipe cleanly. In this situation, you need to adjust the distance between the springs. It could also be due to impurities mixed on the wiper, preventing it from effectively wiping the glass. If present, simply clean them off. 2. Glass: Water streaks may not necessarily be the wiper's fault; there could be an oil film on the glass. This oil film has strong water adhesion and is difficult to remove even with wiper wiping.
I drive quite often and have encountered the issue of water streaks left by the wipers several times. At first, I thought it was due to rainy weather, but later realized it was mainly caused by worn wiper blades or an oily film on the windshield that wasn’t cleaned properly. A simple solution is to first wipe the rubber part of the wiper blade with a damp cloth to remove dust and dirt, then check if there’s any residual oil on the glass—you can spray some specialized glass cleaner and wipe it off. If the problem persists, the wiper blades might be worn out and need replacement. Generally, wiper blades should be replaced every six months or so. While this issue isn’t major, blurred vision during rain can be quite dangerous. That’s why I always advise my friends to check their wipers regularly and not wait until they’re caught in the rain to scramble for a solution. Developing good habits makes driving safer. Oh, and remember not to scrape the glass with hard objects to avoid scratching the surface, which can make it more prone to streaks.
