What Causes the Oxidation and Whitening of the Front Windshield Film?
2 Answers
There are generally two possibilities. The first is an issue with the glass itself, which can only be resolved by replacing the glass. The second is a problem with the film, which would require reapplication. For a detailed diagnosis, it's advisable to visit a 4S shop. Treatment Methods: If the oxidation of the front windshield film is severe, it is recommended to take the car to an auto repair shop immediately for either reapplication of the film or complete removal and cleaning. Advantages of Car Covers: Car covers provide excellent protection for the car's paint and window glass, especially for high-end vehicles. Regular use of car covers can extend the lifespan of the paint, keeping it shiny and new. The front strap is closed, allowing the cover to be slipped on from the front, while the rear strap is open. The elastic hooks on both sides of the cover can then be attached to the lower edges of the car body to secure the cover firmly in place.
I've been running an auto repair shop for ten years and have seen countless cases of whitening windshield films. The main culprit is poor film material with insufficient UV absorber content, which turns white and hazy after prolonged sun exposure. Installation is another issue—if the shop uses low-quality installation fluid or fails to clean the glass properly, bubbles and oxidation will appear within a year or two. If you use corrosive glass cleaner or park near chemical plants, those chemical fumes can also corrode the film. This whitening isn't just unsightly; the glare while driving is dangerously distracting. You'll need to replace the film. I recommend opting for a certified metal-ceramic film with an official warranty, installed by professionals using ammonia-free solution, and cleaned regularly with pH-neutral glass cleaner.
