How to check whether the wiper needs to be replaced

The wiper on the vehicle is a product with safety function. They help keep the windshield clean and flush so you can see road safety. If the wiper blade is not good, the glass surface will be blurred and stained, which will reduce the visibility and bring danger to you and your passengers. This is why the wipers are replaced regularly and important signals and reasons for replacing the wipers are identified.
1. Check the knife edge
Generally, the wiper should be replaced every 6 to 12 months, but the hot summer will reduce its service life. It is best to check the blades and replace them if necessary. You should mainly pay attention to how they clean the windshield. If you find that their work is no longer excellent, it's time to change. In addition, please note whether there is noise, which may indicate that the blade moves unevenly on the glass.
2. Frequently asked questions
There are many things that will tell you that you need to replace the wiper. Understanding the causes can help you better find problems and replace the wiper before the wiper is damaged to avoid potential safety hazards.
For example, water marks are usually caused by dry knife edges. You can check it by checking the blade of the adhesive tape. If it is hard and cracked, you need a new one. However, it may also be caused by other problems. For example, your wiper may be covered with pollen. In this case, you only need to clean the glass and wiper to stop the solution.
3. Causes of blade wear
The wiper tape will wear naturally over time. However, certain factors can accelerate wear. For example, exposure to the sun. This causes them to dry, causing the adhesive strip to crack and break. Unless you can keep your vehicle out of the sun, this is usually unavoidable.
The wax or oil you use on the vehicle may also damage the blade and cause the rubber strip to decompose prematurely. Salt in the air will also degrade the wiper strip more quickly. To avoid premature wear, please make sure to clean the windshield frequently. Do not use wipers to remove frost, snow and dust on the windshield, so as to avoid their contact with other substances you may use. When replacing the wiper blade, it is necessary to ensure good wiper performance. Bad wipers may cause visibility problems in the coming rainy season and threaten your safety.
