Don't forget to maintain the wiper on sunny days.

Wipers look small and simple, but they are quite effective. Driving safety will be a problem without it when it rains. Therefore, it is very important to always pay attention to and do a good job of maintenance. One day, my friend drove back to Guangzhou from Shenzhen, and it began to rain lightly. Raindrops and dust mixed together, making the windshield messy and the people in the car blurred their vision. So I quickly turned on the wiper. Who knows, the wiper of my friend's imported car looks quite new, and the wiper is loud and dirty, which makes the windshield blurred. Fortunately, with a few more strokes, the glass was at least scraped clean. Asked in time, he washed the car diligently, but paid little attention to the wiper strip. After autumn, the weather has been good, and the wiper is rarely used, which has become a "forgotten corner". Maintenance of wiper Although the wiper is placed on the windshield, it is easy to turn a blind eye to it during daily maintenance, and it is only after use that it is known that there is a problem. The maintenance method of wiper blade is actually very simple. Anyone can do it if he wants to. Everyone knows that the windshield will be dirty, but not everyone seems to notice that the wiper blade will be dirty. Please remember to wash the car every time, except for cleaning the glass. It is also best to wipe the wiper blade with glass cleaning liquid, so that the life of the wiper blade will be longer. If the car wash shop helps you clean, remember to remind the clerk to do the work for you. Don't forget to leave some time for the wiper when doing all kinds of maintenance. Put the wiper switch at various speed positions, and check whether the wiper blade works normally at different speeds, especially under intermittent working conditions. Pay attention to whether the wiper blade keeps a certain speed when moving. In addition, check the state of the wiper, and check whether the wiper strut swings unevenly or scratches are missing. Either of these two faults means that the wiper blade is damaged. In addition, pay attention to whether there is vibration and abnormal sound when the wiper works. Regular inspection is very important. If all kinds of faults are complete, the wiper blade must be checked. The method is to pull up the wiper and touch the cleaned rubber wiper blade with your fingers to check whether it is damaged and whether the rubber wiper blade is elastic. If the blade cracks due to aging and hardening, it should be replaced with a new one. The work of replacing the blade is not complicated, just do it yourself. First of all, you need to know what kind of wiper blade is used in the car. You can refer to the manual attached with the car to see the wiper model indicated on it, or drive to the parts store to show the clerk what kind of wiper blade to use. Generally speaking, wiper blades are sold together with metal columns and rarely sold separately. Of course, blades with struts will be more expensive. In addition to the size and specifications of the blade, it is also necessary to pay attention to whether the connection mode between the strut and the wiper rocker arm matches, because some rocker arms are fixed on the rocker arm with screws, while others are locked with built-in convex buckles, so be careful when buying. Only simple tools are needed to install the wiper blade. A Phillips screwdriver is enough. If it is a knob, you don't even need a screwdriver. How to replace the wiper blade: Pull up the wiper rocker arm and remove the screw on the screw fixing arm. Pay attention to the small screw, don't lose it. For the convex button type, just press the convex button to unlock it. Pay attention to whether there is dirt on the convex button. If there is, it is best to spray some lubricant to facilitate disassembly. No matter what kind of arm, be careful not to let the rocker arm bounce back to the glass after disassembly, because the spring installed on the rocker arm has certain elasticity, and the rebound force may damage the windshield. Please remember, don't forget the wiper in sunny days, and the road is safe and secure in rainy days.
