The windscreen wipers scrapes dirty glass and may have the following reasons:
Glass is not clean
Usually, the car wash does not clean the glass well, and the surface of the glass is adhered with fine tar particles, etc., which will reduce the surface finish of the glass. The rough glass surface will not only be scratched, but also will hurt the wiper strip.
windscreen wipers strips are rough
The most important thing to note is to remove the fine sand on the windscreen wipers strip in time. Scraping with these fine sands is equivalent to sanding the windscreen wipers strips with a grinding wheel. After a long time, the finish will drop, and the strip of the donkey will definitely not clean the rain.
The oily film is distributed on the windshield with the use of the wiper, usually due to dirt or car wax attached to the glass; the windscreen wipers strip is contaminated by car wax and oil.
Fine water phenomenon
When the windscreen wipers is brushed over the windshield, there are still small drops of water stuck on the glass surface. This phenomenon is caused by the quality of the car wax, oil stain or silicide sticking to the windshield, rubber strip or strip.
"kada" or harsh noise
When the windscreen wipers is irregularly scraped, it is mostly caused by the wear of the strip, the damage of the arm and the bracket, and the aging deformation of the strip. In the absence of lubrication, there is also a frictional sound when the windscreen wipers sweeps the glass.
How to properly use and maintain the wiper
There must be water to open the wiper
The "knife edge" of the windscreen wipers is very fragile. If something is stuck on the glass, it will easily damage the windscreen wipers, and the water can clean and lubricate, which can protect the windscreen wipers and the glass, and make the glass cleaner.
Clean up the attachments in time
If it is found that the adhesive strip on the strip should be cleaned in time, use a damp cloth to rub the windscreen wipers "knife edge" and keep the "knife edge" clean. If dirt such as bird droppings is found on the glass, it should be cleaned in time. Although the glass will not be corroded, the windscreen wipers will be damaged by these dirt.
Set up a wiper when not in use for a long time
Raise the windscreen wipers to prevent dust from sticking between the strip and the glass. When used again, it will not mix the dust and other materials with the glass water, and will not damage the glass and the strip.
