Cars almost everywhere have wipers because of legal requirements . Vehicles such as hatchbacks and SUVs also have wipers on the rear windows. In addition to cars, other means of transport are also equipped with wipers, such as trains, trams, etc. Some engineering tools, such as cranes, are also equipped with wipers.
2. How often to change wipers
If the wiper has been used for 1-2 years, it is recommended that you replace it in time. At this time, the wiper rubber strip has begun to age after one or two years of wind and sun exposure. To judge whether the wiper is good or bad, it can wipe off the rainwater on the front windshield, especially when it is raining, the wiper is very blurry. Gently lift up the wiper and observe whether the wiper blade has cracks or cracks. If there are cracks or folds , it needs to be replaced.
Check whether the wipers are noisy during operation. If the noise is getting louder and louder, you need to replace them with new ones. Due to the high frequency of using wipers in the rainy areas in the south, the replacement cycle can be shortened according to to local conditions to ensure a clear and clean new vision in rainy weather.
In addition, car owners should be careful not to dry the glass and clean the wipers more often to prolong the service life of the wipers. When you find that the wiper is not clean in the early stage, you can sand it with fine sandpaper. If it is still not clean after sanding, you can replace it at this time.

3. Precautions for the use of car wipers
① As the name suggests, wiper blades clean the rainwater on the front windshield. It can't be used without rain, and it can't be wiped dry without water. The increased frictional resistance due to lack of water will cause damage to the rubber blade and wiper motor.
② Even if there is rain, if the rain is not enough to start the wiper blade, it should not be wiped. Be sure to wait until there is enough rain on the glass surface. The word "enough" here does not obstruct the driver's line of sight.
③ It is not advisable to use wiper blades to remove dust on the surface of the windshield. Even if you want to do this, you must spray glass water at the same time, and never dry scraping without water.
④ If there are sturdy things on the windshield, such as the dried feces of birds such as pigeons, you must not use the wiper directly to scrape it hard. Please clean the bird feces by hand first. These hard things can easily cause partial damage to the thin slices of the wiper blade, resulting in the wiper not wiping the rainwater cleanly.
