I believe we are not familiar with the car wiper. It is the eyelash of the car that provides us with a bright view in rainy and snowy weather. Many car owners rarely replace the wiper after buying the car. Although it is said that the wiper is a consumable, it can be used for a long time in a well maintained environment.

So, do you know what is bad for cars that do not replace the wiper for a long time? The following editor will tell you about his disadvantages. There is a great chance that the wipers of vehicles that have not been replaced for a long time will fail when driving. The probability of this kind of failure is much greater than that of replacing the car wiper frequently. Especially on the highway, this kind of fault often accompanies the occurrence of accidents. Therefore, it is very important for driving safety to replace the wiper frequently.

Then how can we determine whether the wiper reaches the time of replacement?

1. Wash the wiper first, lift the wiper and touch it on the rubber to check whether it is damaged and whether the elasticity of the rubber blade is good. If the rubber is pulled gently, cracks or cracks will appear if the blade is aged and hardened. If so, it must be done immediately and faster.

2. Check the wiper carefully. If the tension of the wiper arm spring becomes weak and the wiper is found to be warped, the wiper arm needs to be replaced.

3. Some car owners found that their wipers were in good condition when it rained heavily, but when it rained lightly, they would leave unclean and uneven water marks on the glass. Professionals pointed out that this situation is not that the car owners think there is oil on the glass surface, but that the wiper has hardened and needs to be replaced.
