What causes unclear aging of car glass after 10 years?

Unclean glass is most likely caused by prolonged exposure to the outdoors, forming an oil film due to factors like smoke. Mix dish soap with water and scrub vigorously, then rinse with clean water. No need to buy special cleaning solutions - this is the most cost-effective method. Remember to regularly clean the wiper blades by wiping the rubber strips with a towel or tissue. Relevant information about wipers is as follows: 1. Introduction: Wipers, also known as windshield wipers, are devices used to remove raindrops and dust attached to the vehicle's windshield, improving driver visibility and enhancing driving safety. 2. Usage: On rainy days, when raindrops fall on the windshield, the view ahead quickly becomes obstructed, making vehicles, pedestrians, and scenery appear blurry. At this point, turning on the wipers will restore clear visibility ahead.
My old car has just hit the ten-year mark, and the windshield is indeed starting to get blurry. Back in the day, a quick swipe of the wipers in the rain would make it crystal clear, but now it always feels like there's a layer of oily film. This is actually due to the aging of the hydrophobic coating on the windshield surface. Years of sun, rain, and repeated friction from car washes have worn off the coating, causing water droplets to bead up. Also, when the wiper blades age, not only do they fail to clean properly, but they can also leave fine scratches on the glass, causing light from street lamps to scatter. If the inside of the glass feels greasy, that’s due to oily dust deposited from the air vents blowing onto the glass and forming a sticky film. My advice is to thoroughly clean both the inside and outside of the glass first. If the wipers are old, replace them immediately. If the coating is gone, you can buy a glass water repellent and apply it yourself as a fix.
We girls are most afraid of unclear visibility when driving, especially with older cars that have been on the road for ten years. A foggy windshield could be due to three layers of issues: the outermost layer is slight erosion of the glass material caused by long-term sun exposure, which feels gritty to the touch. The middle layer consists of star-shaped cracks from roadside flying pebbles that gradually oxidize and turn yellow. The most annoying is the inner layer, where dust from the air conditioner mixes with perfume volatiles, forming a sticky film on the glass that is particularly glaring when driving into sunlight. Last time, I used kitchen paper towels dipped in medical alcohol to vigorously clean the inside, and it became much clearer immediately. Of course, if there are cracks in the glass, it's necessary to replace the windshield promptly.
