How to Remove Aged Window Tint Film?
2 Answers
For aged window tint film that cannot be peeled off, you can use a specialized tint film blower. This method involves heating the outer surface of the film by blowing hot air. Avoid blowing air over large areas to prevent the previously heated sections from cooling down and rendering the effort ineffective. After heating a small area, use a specialized tint film scraper to remove the heated portion.
Last time I DIY removed aged window film, I first used a hair dryer to heat the entire glass surface while gently peeling the edges. Heating is crucial - old film becomes extremely brittle and will shatter into pieces if removed cold. After peeling, I sprayed alcohol on residual adhesive, waited a few minutes, then slowly scraped using a bank card wrapped in a towel. This budget method saves money without damaging glass. For tricky corners, I carefully used a utility knife with cloth-wrapped blade to prevent scratches. The entire rear windshield took three hours - my fingers were sore, but I saved over 200 yuan compared to shop service. After removal, thorough degreasing is essential to prevent bubbles under new film.
