Why is the car windshield always blurry no matter how you wipe it?

[VanMaya]

Generally, it is caused by spots, dirt, glass rust or oil film on the windshield. When this happens, it greatly affects driving visibility. Especially when the rain is not heavy, it is more likely to cause oil stains and dirt to remain on the windshield, leading to driver misjudgment. Therefore, cleaning the windshield is necessary. Here are the relevant solutions: 1. Use a towel: If the dirt is slight, you can wipe it directly with a towel without using car body cleaner, and it can be cleaned immediately. 2. Use special glass cleaner: If there is a lot of dirt attached to the glass and it is difficult to remove by ordinary methods, then you need to use special glass cleaner to wipe it. Its function is to make oil film and other dirt less likely to adhere to the glass.
