The wiper is not clean and there is an oil film. How often should the car wiper be changed?

With the passage of time, it is difficult to avoid some minor problems, and the oil film on the windshield as we call it today is one of the phenomena.Although this kind of oil film has no effect in daily driving, it is worse in rainy days, because the hydrophobicity of this kind of oil film is very poor, even if it is usedWiperThe scraper is also difficult to clean.

What should I do if the wiper is not clean and there is an oil film? In fact, the removal method is relatively simple. We only need to use the cleaning effect of the glass cleaner to remove the oil film on the glass. But everyone must not underestimate this problem. After all, the wiper is not clean, which has a direct impact on the visibility, so it is better to pay attention to it. As for how to judge whether there is an oil film, just pour a bottle of water directly on the glass. If there are many small water drops attached to it, it means that there is indeed an oil film on the glass. Of course, if the wiper is not clean, it may remind you to replace it.

So how often do the car wipers change? Generally speaking, the wiper replacement cycle is 1-2 years, but in the end it depends on the quality of the wiper. You must know that the wiper is a rubber product, and bad quality rubber often does not have good heat resistance. Then, the aging (hardening) of the rubber will be accelerated under long-term exposure, and it may be scrapped in less than half a year. So we'd better go to the formal channel to buy the wiper, so that the quality is guaranteed.
