Over time, the film on car windows may become old and require removal. Below are some methods to help car owners quickly remove old film.
1：Using Chemical Solvents
First, spray a moderate amount of ammonia solution on the old film and cover it with a garbage bag or plastic wrap. Park the car in sunlight to allow the heat of the sun to accelerate the action of the solvent. This will soften the old film and make it easier to peel off. Note that if the ammonia method is ineffective, you can try using a dedicated adhesive remover. Dripping alcohol is also a viable option; just wait for them to soften the adhesive of the film.
2：Physical Peeling Techniques
Prepare a sharp utility knife and a hairdryer, then use the utility knife to create gaps at the edges of the old film. Next, turn on the hairdryer and heat the gapped area on low heat mode. When the adhesive of the film hardens, slowly peel off the film by hand. Be sure to handle with care to avoid damaging the vehicle's glass.
The difficulty of removing old film may vary depending on the quality of the film. For lower-quality films, they can be directly torn off or removed with professional tools. However, for higher-quality films, more cautious methods are required. Whether choosing chemical solvents or physical peeling techniques, ensure to perform the operation safely, attentively, and patiently to prevent damage to the vehicle.
