How to remove the film on car lights after a long time?

The method to remove the film on car lights after a long time is: 1. First, you can use your fingernail or a hard card like a bank card to lift one corner of the film. If that doesn't work, you may need to use a wallpaper knife. 2. Then, you can slowly peel off the film. If you want to speed up the process, you can use a heat gun to assist in removing the film, as heating can significantly reduce the adhesive's stickiness. 3. After the film is removed, there might be some residual adhesive left on the surface. At this point, you can use alcohol, tar remover, or hot glue to remove it, followed by rinsing with tap water.

As someone who frequently works on DIY car repairs, I've encountered the issue of headlight film aging, turning yellow, and hardening several times. The key to removing them is softening the adhesive: I use a household hair dryer on the hot setting to blow air onto the film for a few minutes until it softens, then slowly peel it off while pulling. If there's any adhesive residue left, I wipe it clean with isopropyl alcohol or white vinegar on a cloth, avoiding metal tools to prevent scratching the headlight surface. Afterward, applying some protective wax or replacing the film helps prevent oxidation—it's both cost-effective and practical. This treatment makes the headlights much brighter, almost like they're brand new. If you're impatient, I recommend doing it in multiple sessions to avoid rushing and damaging things. I learned this technique from online videos, and now I'm quite handy with it.

With years of auto repair experience, I recommend a professional method for removing old headlight film: Use a heat gun to evenly warm the film surface for a few minutes, then gently peel it off. Apply a specialized adhesive remover to dissolve any residual glue. Wear gloves during cleanup to prevent skin irritation. After completion, rinse with mild soapy water, dry, and polish to restore clarity. For severely brittle film, a plastic scraper can assist but avoid excessive force. This prevents damage to the lens that could compromise nighttime driving safety. DIY is cost-effective, but if you're inexperienced, professional service is safer.

I believe safety comes first when removing old headlight film. I would use a hairdryer to heat and soften it before peeling it off slowly, then use alcohol wipes to remove any adhesive residue. Ensure hand protection to avoid scratching the headlight surface. After cleaning, check the degree of light transmission recovery. If it's insufficient, replace it with new film for maintenance.
