Many drivers encounter situations where wipers are turned on but water still sticks to the windshield, visibility is blurred or there is glare when driving in the sun. According to advice from technicians at Ninety Eight Auto Auto Repair, Maintenance and Care Center (Thu Duc City, Ho Chi Minh City), the common cause comes from small scratches on the glass surface, formed during use and improper cleaning.
Among them, many people have a habit of using a hard cloth to wipe the glasses. Although this does not scratch the glasses immediately, if repeated for a long time, it will create scratches on the surface.
In addition, wiping glasses when there is still a lot of dust with a dry cloth is also a common cause. Hard dust particles combined with the friction force of the cloth can wear down the glass layer, creating small scratches that are difficult to recognize with the naked eye but have a clear impact during use.
When scratches have appeared on the windshield, the wipers will find it difficult to completely clean the water on the surface. Water tends to stagnate in the scratched grooves, making the windshield blurred, reducing the driver's visibility, especially in heavy rain conditions.
Not only that, during the day or when direct lights are on, scratches will cause light scatter, making drivers dazzled and difficult to concentrate on observation. This increases the risk of unsafety when driving.
According to a technician at Ninety Eight Auto, the effective solution in many cases is to polish the windshield instead of replacing it. This process includes two stages: scratch removal and glass surface polishing.
For glasses that are only stained or blurred due to use, polishing can help restore transparency. However, if many scratches have appeared on the glasses, it is necessary to take additional scratch removal steps before polishing to improve visibility and increase driving safety.
For cases where the windshield is kicked off causing deep breakage, handling can only partially improve the damage situation but it is difficult to completely restore it to the original state. When the crack or breakage is too large, vehicle owners should consider replacing the windshield to ensure safety during use.
