Why is the glass on my 10-year-old car unclear due to aging?

The glass may be unclean, most likely due to prolonged exposure to the outdoors, forming an oily film from smoke and other factors. Mix dish soap with water and scrub vigorously, then rinse with clean water. There's no need to buy special cleaning solutions. Remember to clean the wiper blades regularly by wiping the rubber strips with a towel or tissue. Here are methods to remove the oily film: Dish soap: Every kitchen has it, but it can only partially remove the oily film, not very thoroughly. After some use, the oily film will still appear. Toothpaste: Toothpaste is like a universal cleaner. Its abrasive particles and oil-repellent function make it more effective than dish soap in removing the oily film, achieving a more thorough removal, though it's not as convenient to use as dish soap. Oily film remover: Oily film cleaners work the best. Compared to toothpaste, they are more durable and cheaper. If not in a hurry, you can use an oily film cleaner. It's best to apply several coats of protective film to your car glass regularly—prevention is the best approach.
My car has been driven for over 10 years, and the glass surface has started to become blurry. I guess it's due to long-term exposure to sunlight and rain erosion. Every morning when I drive to work, I can see a thin layer of fog on the glass, especially in summer after being exposed to the sun, the plastic edges have turned yellow. The aging of the glass is mainly caused by UV radiation damaging the coating, combined with the accumulation of dust and stains forming tiny scratches that refract light irregularly. I remember one time I parked outside without a car cover, and impurities in the rainwater seeped into the cracks, making it even more hazy. In this case, ordinary cleaners won't clean it properly; it's recommended to try glass polishing paste or replace the glass to improve visibility. For regular maintenance, it's best to park in a sheltered place and avoid hard objects scratching the glass surface. These small habits can slow down the aging process.
