What causes unclear aging of car glass after 10 years?

[DiAnnie]

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.
