How to replace wiper blades and maintain them?

A good set of wiper blades is very important for a car. Without wiper blades, driving in a downpour is almost impossible and presents a very big safety hazard. Since wiper blades are essential for safe driving, it is a wise idea to keep them updated. But how do you know when to replace wiper blades, and which wiper blades should you buy?

The general service life of wiper blades is about 1-2 years, and if they are well maintained, they can be used for 3-4 years. When you find that some of them are not scraped clean, you can use fine sandpaper to polish and refurbish them, which is said to have a certain effect. If the scraping is serious or the age is reached, it is better to replace it as soon as possible. After all, it is not expensive and it is relatively simple to replace. The most important thing is that it can ensure that your vision is clear enough when it rains and avoid the existence of safety hazards.

How to check whether the wipers should be replaced?

1. When it rains heavily, it feels good to use the wiper, but when it rains lightly, the wiper leaves uneven traces on the glass surface, affecting the field of vision. This indicates that the wiper has hardened and needs to be replaced;

2. Pull up the wiper and touch the cleaned wiper rubber with your fingers to check whether there is any damage and the elasticity of the rubber blade. If the blade is aged, hardened, and cracked, it needs to be replaced;

3. When the tension of the wiper arm spring weakens, the wiper arm needs to be replaced. The wiper blade is in close contact with the windshield with the help of the wiper arm spring. When the tension of the spring weakens, the wiper will float due to the strong wind pressure brought to the windshield by high-speed driving, resulting in part of the glass not being wiped. At this time, it is best to update the wiper arm;

4. If the glass surface is foggy, fine water droplets, stripes or partially blurred when the wiper is working, this is due to the influence of oil film, dirt or car wax. At this time, it does not need to be replaced. Just clean the windshield and wiper blades. If the wiper is partially aged or worn in a small area, you can use sandpaper to polish the wiper. Because the wiper itself has a certain thickness, it can still be used normally if a thin layer is polished off. But when polishing, you must pay attention to the uniform polishing of the entire wiper blade. Generally, the wiper should be replaced every six months to a year.

What should be paid attention to when using wipers in daily life?

1. Avoid dry scraping

Glass water is very cheap, and it only costs a few dollars a bottle in the auto parts city. Don’t be reluctant to use it. Especially on sunny days, if there is a little floating soil, don’t scrape dry. Use it with glass water, otherwise it will seriously damage the rubber of the wiper.

2. Reduce exposure

When the vehicle is parked in the hot sun, the temperature of the front windshield is very high, and the wiper rubber strip that was originally close to the glass will accelerate aging due to the high temperature. Therefore, when the vehicle is parked in an outdoor parking lot, we can stand up the wiper to reduce the contact between the wiper rubber strip and the hot glass and extend the service life of the wiper.

3. Do not change the size of the wiper blade at will

Some car owners always like to buy 1-2 inch longer wiper blades when replacing them, thinking that the wiper area is larger and the effect is better. In fact, this is wrong. If the wiper blade is too long, it may wear the A-pillar trim or the front windshield cover during operation, which can cause resonance and abnormal noise. The right choice is to use a special size for a special car.

4. Stop and rest in heavy rain

Before turning off the engine, scrape away the residual rain and snow on the front windshield to avoid the dust raised by the parking lot and the residual liquid from mixing and drying on the glass, causing the rubber strip to deform when the wiper is used next time. After the rain and snow, clean the wiper strip with clean water in time to avoid corrosion of the wiper strip due to some harmful substances contained in the rain and snow.
