How to Remove Rain Guards?

Directly peel them off. Poor-quality films are relatively easy to handle, while high-quality car films are quite challenging and require seeking professional help or purchasing specialized tools. The key professional tool is an adhesive removal knife, which is specifically designed for adhesive removal, and its blade differs from ordinary knives. At this point, you need to visit some car detailing shops to purchase cleaning solutions or ask the professionals there to assist with the removal.
The rain repellent film on my old car's windshield has aged into a hazy mess, and I've cleaned it myself several times. First, I mix hot water with dish soap to make a concentrated solution, then use a sponge to thoroughly scrub the glass surface in circular motions. Next, I press an old bank card scraper at an angle against the film and slowly push it forward like scraping off frost. Remember to work in small sections—each about the size of a rice bowl—and apply gentle pressure, as moving too quickly may leave scratches. After scraping, I wipe off any residual oily marks along the edges with alcohol swabs, then rinse thoroughly with clean water. The entire process is best done in the shade, as direct sunlight can cause the cleaning solution to dry too quickly. This method saved me hundreds in auto repair fees, though it tests one's patience—it took nearly an hour just to finish the rear window.
To efficiently remove the rain film from the windshield, having the right tools is key. I've specially prepared a set of car detailing equipment. First, spray tar remover to soften the film, wait five minutes for it to fully dissolve, then gently scrape it off with a rubber scraper. For stubborn areas, use a nano sponge dipped in adhesive remover for spot cleaning, wiping twice before absorbing the residue with a fish-scale cloth. The crucial step is to protect the rubber seals around the window edges by covering them with painter's tape beforehand to isolate them from the cleaning solution. Immediately after finishing, spray a layer of glass water repellent to form a protective film, preventing raindrops from sticking. This method is less labor-intensive than pure physical scraping, taking about twenty minutes to complete the entire front windshield. However, it requires purchasing professional cleaning agents, totaling a cost of around seventy to eighty yuan.
