What to do if the windshield wiper is not clean when it is raining

I believe many car owners will have encountered it on a rainy dayWiperThere was a foggy phenomenon, but many unknowing friends thought that something was wrong, so they went directly to the 4S shop for inspection and repair. In fact, this does not need to be so laborious, it may be just a few minor problems. Next, let's discuss what to do if the wiper does not scrape the glass cleanly.

when weFindWhen the wiper is not properly hung, we must first check whether there are any foreign objects between the wiper blade and the windshield. If there is any, it should be cleaned up in time, otherwise it will not only cause foggy problems, but also may be accompanied by obvious abnormal noises. The second is the problem of quality. Wiper blades of poor quality often do not have very good resistance. They are prone to hardening under long-term exposure, and naturally they will not be clean. At this time, it needs to be smoothed with sanding paper. Of course, it is best to directly replace one.

But not all the reasons are from the wiper, in fact, it has something to do with the front windshield. When the car is exposed to the sun and rain for a long time, oil film is prone to appear on the glass. And this kind of film is usually relatively low hydrophobic, even if it is wiped with a wiper, it will be blurred. Therefore, for driving safety, it should be removed with a glass cleaner as soon as possible. As for how to judge whether there is an oil film, the most direct way is to pour a basin of water on the glass and observe the hydrophobicity on the glass.
