How to remove the old car film from the car glass?

Method of removing used car film: \x0d\ 1: It is easier to tear off inferior film directly. The adhesive strength of this film is not particularly good and it is easy to remove. High-quality car film is difficult to remove, so you need to find a master or buy your own professional tools to deal with it. \x0d\ 2: Remove vinegar \x0d\ Apply vinegar evenly on the adhesive with a cotton swab. Through the glass, we can immediately see the slow diffusion of vinegar between the glass and the adhesive. Then scrape the glue back and forth with a cotton swab. Soon, the glue began to peel off one by one, and there were few glue residues on the glass. Wiped with paper, as bright as new. \x0d\ III: Removing the essential balm \x0d\ When the essential balm and the adhesive are in contact, there is no obvious change. Stick to the balm on the glue, and then scrape it clean with a cotton swab. Slowly, I found that the glue softened and some glue had been scraped off. With constant smearing and scraping, the two people's reactions are getting faster and faster. About 2 minutes, a sticker was removed. \x0d\ IV: Alcohol removal \x0d\ I brushed the glue on the glass with alcohol and immediately saw that the glue was slowly softening and dissolving. Gently lift it with your hand and the glue will leave the glass cleanly.
