When the driver of the car drives the car on a rainy day, the most needed is a wiper to clean the windshield to provide a view to the riders. Then the wiper is Isn't there also a life span? How often do you change it? Many drivers are not very familiar with this issue. The following are some of the issues that Xiaobian has compiled for the riders. 
Generally, the life of the wiper blade is about 1-2 years, and it can be used for 3-4 years if it is well maintained. When it is found that some of the scratches are not clean, you can use a fine sandpaper to polish and renovate. If the scraping is not serious or it is a long time, it is better to replace it as soon as possible. After all, the price is not expensive, and it is relatively simple to replace.
How to repair the wiper every day?
What we call the maintenance of the wiper is mainly to keep the wiper blade clean, to avoid excessive dirt on the wiper strip, and not to mix foreign matter. If the wiper is mixed with foreign matter, it will not be cleaned, not only speeding up the aging of the wiper strip, but also easily scratching the front windshield.
The correct way is to remove the foreign matter and dirt from the wiper strip at each car wash or regularly, first wash it with water, then wipe the wiper strip with cotton cloth or paper towel, so that it is not only clean, but also used time. Still long.
1, avoid dry scraping
Glass water is very cheap, don't want to use it. Especially on sunny days, do not dry up a bit of floating soil, use it with glass water, otherwise it will seriously damage the rubber of the wiper.
2, reduce exposure
The vehicle is parked under the scorching sun. The temperature of the front windshield is very high. The wiper strips that are close to the glass will accelerate the aging due to the high temperature. Therefore, when the vehicle is parked in the outdoor parking lot, we can erect the wiper to reduce the contact between the wiper strip and the hot glass to extend the life of the wiper.
3. Don't change the wiper size at will.
Some car owners like to buy a 1-2 inch long when replacing the wiper blade, and feel that the scraping area is larger and the effect is better. In fact, this is wrong. When the wiper blade is too long, it may wear the A-pillar trim or the front windshield cover, which can cause resonance and abnormal noise. The special size of the car is the correct choice.
The above is some of the relevant knowledge about car wipers that Xiaobian has compiled for the riders. In the daily life, the riders need to know more about this aspect to enrich themselves.
