Under what circumstances will the car wipers
not wipe cleanly? After the rubber strip of the wiper blade is aged and hardened, the fit with the glass is not very good, and there is a gap before the glass, so there will be a phenomenon that the wiper is not clean. It is recommended to replace the wiper blades.
First, check whether the rubber strip of the wiper blade is aging and hardened, which causes the wiper to hang uncleanly and abnormal noise occurs.
If the wiper blades are not clean 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 air with dust and foreign objects, such as resin, on the windshield. This will cause the wiper to wipe clean. At this point, the windshield needs to be cleaned. Car wash mud can be used to remove dirt and resin from the lower windshield.
The replacement cycle of wiper blades is generally about once a year. When the wiper blades have the following symptoms, it may be necessary to replace them in advance:
1. Damages that can be identified with the eyes: cracks, cracks, aging, rust, deformation, attachments, discoloration, etc., it is recommended to replace the wiper blade in time.
2. The damage that can be identified by ear: the rubber strip has fallen off from the skeleton, 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 wiping effect to identify: When you are using the wiper, if scratches will be left on both sides or the middle glass after each wipe, it is recommended to replace the wiper blade.
There are two types of wiper blades, one is a boneless wiper, and the other is a bone wiper. There are more mainstream boneless wipers on the market now. Because there is no frame, the wiper blade and the windshield fit better, so the wiper will wipe more cleanly.
