Regular inspection: The method of checking the wiper is very simple, spray some cleaning fluid, and then turn on the wiper, pay attention to whether its movement is smooth, pay attention to whether there is a loud "scraping" sound, if any, it means the wiper Excessive pressure is applied to the glass, and proper adjustment must be made at this time. After the wiper has been swept one or two times, check to see if there is any moisture left on the windshield. At the same time, observe if there are some scratches. If it is obvious, it means that the wiper strip on the wiper has been It is aging and should be replaced with a new one.
Avoid prolonged exposure: avoiding prolonged exposure to the sun can make the wiper last longer. One point is that the car should be very careful: when you find sand on the glass, you often only turn on the wiper to sweep away the sand. This is very important. Wrong, the fact that doing so will greatly damage the wiper strip and the car glass. So before turning it on, you might as well spray a little cleaning fluid first. Of course, manual cleaning is better. When maintaining the wiper, you should also pay attention to maintaining the water spray system of the car: add neutral, decontamination, and lubricating cleaning agents; bad cleaning fluid will corrode the water spray system, wipers and car finish. Fill water in time to avoid idling the water spray motor.
Keep away from oil stains: Because there is oil stains on the glass, the water stains are easy to condense into water droplets when they meet with water. If they can't be removed, water is prone to appear. In the same way, if you accidentally touch oil stains on the windshield of a car or wiper, it will not clean the rain. Although the wiper is placed on the windshield, it is easy for people to ignore it during daily maintenance. If oil stains are found on the glass, it is best to wipe the wiper strip and glass with glass cleaning fluid when washing the car.
