How to Remove Oil Film on Car Windows?
3 Answers
Here are methods to remove oil film on car windows: Dishwashing Liquid: Dishwashing liquid contains hydrophilic and lipophilic groups, which can dissolve oil and water together, effectively removing oil stains. Oil Film Cleaner: Spray the cleaner evenly on the window, then use a car wash towel or sponge to clean and wipe it off for better results. Toothpaste: Toothpaste contains abrasive particles that can polish the surface. Evenly wiping with toothpaste can clean the pores on the window surface and remove the oil film. Eraser, Clay Bar, or Newspaper: An eraser or clay bar can scrub off the oil film, while newspaper has some oil-absorbing properties. Dampen it with water and wipe repeatedly to eliminate the oil film.
I just discovered a practical trick for dealing with windshield oil film! Last week, I tried a mixture of dish soap and toothpaste, and the results were great. Mix two spoons of dish soap with warm water, squeeze out five centimeters of toothpaste, stir well, and use a sponge to scrub the glass in circular motions. Don't rinse it off immediately—wipe it dry with old newspaper twice, and the oil film will disappear completely. The key is that it's easier to do on rainy days, as water droplets make the oil film more visible. This month, I didn't have to visit the car wash, saving over 300 yuan. However, for stubborn oil films, you still need professional oil film remover, which costs 30 yuan at the auto parts store and lasts half a year.
Oil film is actually an organic mixture adhering to the glass, with tree sap mixed with exhaust grease being the most troublesome. Last time, the repair shop technician taught me: choosing an oil film remover containing abrasive particles paired with a nano sponge is the most reliable method. First, wet the glass, spray the cleaner, then wipe from the center outward in circular motions. Never scrape dry, and observe whether the water flows in sheets when rinsing. If large water droplets remain, repeat the process. Remind everyone to deal with oil film before the rainy season, as scattered lights on waterlogged roads are particularly dangerous. I now clean it quarterly for safety and peace of mind.
