What Causes the Front Windshield of a Car to Be Unclear?

[VanChristopher]

There are several reasons why the front windshield of a car may become unclear, including dust and spots. Dust: Since cars are often driven outdoors and many parking lots are open-air, it is common for dust to accumulate on the windshield. In such cases, the owner can easily clean it by wiping the surface with a towel first and then washing it with glass cleaner. Regular cleaning can resolve this issue. Spots: Spots usually appear due to rain residue. A routine cleaning process, such as wiping with a towel and then using glass cleaner or toothpaste, can remove them. This method is similar to the one described for dust and is relatively simple. Glass Stains (Glass Etching): If there are glass stains, the situation becomes more troublesome. Sometimes, detergents or dish soap are used, but they may not effectively remove the stains. The correct method involves first wetting a towel, wiping the glass with the damp towel, applying alcohol, and then wiping again. Alternatively, adding ammonia to water can also help remove the stains.
