How to Remove Rear Window Film Without Damaging the Heating Wires?

Use a hard card similar to a bank card or a wallpaper scraper to lift a corner of the rear window film. Usually, some corners will naturally peel up. Then, slowly peel off the car film, but avoid sudden forceful pulling, as this can easily damage the heating wires. You can use a hairdryer to assist in the process. After removing the film, there may be some adhesive residue left on the glass. Spray alcohol onto a cloth and wipe the adhesive areas a few times to clean them off. Once the cleaning is complete, open the car window to allow any odors to dissipate completely.
A while ago, when I was removing the rear window film myself, I realized how fragile the heating wires really are. I set the heat gun to medium temperature and blew on the film for 20 seconds to soften the adhesive, then gently lifted a corner with my fingernail and slowly peeled it off. After removal, there were adhesive marks left on the glass, and it's crucial not to scrape them off hard with a blade. Instead, cover the adhesive marks with kitchen cling film, spray some alcohol to moisten them, wait ten minutes for the adhesive to soften, and then gently scrape it off with a plastic card like a bank card. The whole process should be as gentle as wiping a baby's face. If you encounter particularly stubborn adhesive spots, just repeat the process a few more times. The entire glass took about two hours to clean, and although it was tiring, not a single heating wire was damaged. Finally, rinse it clean with water, and the glass will shine like a mirror.
I've removed rear window tint film three times, and my experience is that not using tools is actually the safest method. First, park the car under direct sunlight for half an hour to let the film naturally bubble up. Then apply painter's tape along the edges to protect the car body. Use your fingernail to create a small opening, and while blowing hot air, pull the film steadily at a constant speed. Stop when reaching areas with heating wires, then switch to using a hair dryer to heat the film inch by inch. For adhesive remover, neutral cleaners are the safest choice - apply it to a microfiber cloth and rub in circular motions while avoiding the wire areas. The key is to keep the glass moist throughout the process, using a wet towel to wipe away softened adhesive residue. Limit each operation to under 10 minutes to allow the heating wires to cool down. Although this method is slower, even professional tint shop owners acknowledge it causes no damage to the vehicle.
