What is the situation that the car wiper is not clean? After the rubber strip of the wiper blade is aged and hardened, it will not fit well with the glass and there will be a gap in front of the glass, so the wiper blade will not clean. It is recommended that the wiper blade can be replaced. First, check whether the rubber strip of the wiper blade is aging and hardened, which leads to the appearance of unclean wiper hangers and abnormal noise.
If the wiper blades are not cleaned and there are abnormal noises after replacing the wiper blades, it is likely that the windshield is too dirty. The vehicle is parked in the open, and there is dust and foreign objects on the windshield, such as resin. This will cause the wiper to be unclean. At this time, the lower windshield needs to be cleaned. You can use car wash mud to clean the dust and resin on the lower windshield.
The replacement cycle of wiper blades is generally about once a year.
When the wiper blades have the following symptoms, they may need to be replaced in advance:
1. Damages that can be distinguished by eyes: cracks, cracks, aging, rust, deformation, attachments, discoloration, etc., it is recommended to replace the wiper blade in time.
2. Damage that can be distinguished by ears: The rubber strip has fallen off from the frame, and every time it is wiped, it will slap the front windshield, making abnormal sounds such as jumping and shaking. It is recommended to replace the wiper blades in time.
3. Look at the wiper effect to distinguish: when you are using the wiper, if there are scratches on both sides or the middle of the glass after each wipe, it is recommended to replace the wiper blade.
