To avoid deformation of the brushes, it is necessary to regularly clean the windshield wiper blades with a glass cleaner. If the brushes are heavily soiled, for example, with insect residue, the brushes should be cleaned with a sponge or a clean cloth.
For safety reasons, you should replace your windshield wiper blades once or twice a year.
In freezing temperatures, before turning on the windshield wipers for the first time during a trip, you should check whether the brushes are frozen to the glass!
If the brushes do not clean the windshield well enough, the following reasons may be possible:
- when the car passes through an automatic car wash, wax particles get on the windshield. These particles can be removed by adding a glass cleaner with wax-dissolving properties to the windshield washer fluid. Filling the fluid reservoir with a glass cleaner with wax-dissolving properties can significantly improve the performance of the windshield wipers. Grease-dissolving cleaners are not able to completely clean the glass;
- damage to the brushes can also be the cause of poor glass cleaning, the brushes should be replaced;
- the installation angle of the windshield wiper arms does not correspond to the required one.
