What is the reason for the loud noise of car wipers?

Many car owners ignore the maintenance of wiper blades.
If the wiper blade is not clean, it will cause a certain safety hazard to our travel. Therefore, the maintenance of wiper blades also needs to be paid more attention.

Here are some basic common sense about wiper blades.
one
Wiper blade aging
The wiper blade is a rubber product, which will age and harden after a period of time. This phenomenon is more obvious in winter. If the wiper is not clean, the easiest and most effective way is to replace the wiper blade with a new one. The replacement cycle of wiper blades is generally 1-2 years.

two
There is a foreign object in the middle of the wiper blade
When the wipers are turned on, there is a high-pitched sound of the wiper blades rubbing against the front windshield. If there is a sharp sound, the owner can check and remove the foreign matter under the wiper blade or the wiper by himself, so as to ensure that the position where the wiper blade stays is clean. If you do not remove foreign objects, not only will it not wipe cleanly, but it will also damage the wiper blade.

three
Incorrect installation angle of wiper arm
If the wiper arm is improperly installed, it will affect the wiper blade jumping on the windshield, which will cause abnormal noise. The correct installation position is that the wiper blade should be perpendicular to the plane of the windshield.
