Common Wiper Problems
Strip-shaped streaks: The optimal support point for the wiper blade was not found, resulting in the wiper blade failing to make full contact with the glass across all areas. Improper arm pressure, damage to the upper structure, or even an improperly fitted wiper blade can all cause this phenomenon.
Hazy streaks: A thin, oily film forms on the windshield as the wipers are used, typically caused by dirt, grime, or wax residue adhering to the glass. This phenomenon can also occur when the wiper blades become contaminated with wax or oil stains.
The "fine water phenomenon": After the wiper blades have passed over the windshield, small water droplets still remain adhered to the glass surface. This phenomenon is caused by wax, oil stains, or silicates adhering to the windshield, the rubber seals, or even the quality of the seal strips themselves.
“Kata” sounds or harsh noises: Irregular wiper operation is usually caused by worn rubber blades, damaged arms and brackets, or aging and deformation of the rubber blades. Even when the wipers are clean and functioning properly without lubrication, friction noises may still occur as they scrape across the glass.
Wiper lift phenomenon: This is a common aerodynamic issue in modern vehicles, particularly with long wipers. When a car is traveling at high speed, the wind exerts an upward force on the wipers, causing them to lift slightly and leaving some areas uncleaned—this is precisely the phenomenon known as wiper lift.
Cracking of the rubber strip: Rubber strips naturally have a limited lifespan. Under the relentless onslaught of temperature changes, acids, and alkalis, hardening, cracking, or even peeling is inevitable. In some cases, the wiper blade may even fall off directly from the wiper arm. If the rubber strip is of poor quality, it will deteriorate even more rapidly.
Wiper blade hardening: Direct exposure to sunlight and drastic temperature changes cause the wiper blades to harden and lose their elasticity.
Damage to the upper structure: The wiper arm structure was damaged due to being struck by an ice scraper or external force.
Corrosion or wiper strip wear: Poor weather conditions, improper use of cleaning products, or substandard wiper strip formulations can cause the edges of the wiper blades to become frayed or completely worn out.
Wiper strip damage: The primary cause is the accumulation over time of oil stains and car wax on the wipers. As these substances adhere to the wiper blades, gaps may form between the wipers and the windshield, preventing them from effectively wiping away water. If such conditions persist without timely resolution, your wipers will continue to deteriorate, potentially scratching the glass and seriously compromising driving safety.
