Advice from car maintenence experts suggests that users should replace the lever after 12-18 months of use to ensure that it stays in the best working condition.

1. When to replace the windshield wiper?

For cars that are often parked under direct sunlight, the rubber blades can become so brittle and cracked that the wipers may fail to properly grip the windshield. This makes it much more difficult to remove dirt and rain to clear the driver’s vision. Therefore, if your wiper blades are making loud squeaking noise, or if they are visibly vibrating when moving across the windshield and not doing a very good job of clearing the stains and water vapors off the glass, then it is probably a good time to decide whether or not to replace your old wiper.

In addition, the wipers also have pressure points or small arms with a spring that distributes pressure along the rubber blade and creates a force to keep the blades flexed against the windshield. If the spring force is weak, the lever cannot exert enough pressure to effectively clear the windshield. At this point, the driver should check the lever. If even a small force can pull the lever off the glass, it is best to replace the wiper blades.

2. How to replace the wiper blades?

Replacing the wiper blades is not too complicated - the driver can do it without having to drive to the repair shop. You just have to keep in mind that each vehicle will require wipers of different sizes and shapes, so you’d better read your car manual to choose the right wiper type and size as specified by the manufacturer.

In order to extend the life of your wiper blades, it is advisable not to leave the car parked outdoors in the sun for long periods of time. If a properly guarded garage is not an option, the driver should equip the vehicle with a car cover.

Also, to protect the windshield wipers, drivers should regularly check and wipe the dirt off the blades every 4-6 months of use to prevent the buildup of dirt. You should not use conventional bleaches to clean the lever or the glass, but should opt for a specialized glass cleaner to avoid damaging the rubber blade.
