Reasons for the formation of oil film on car glass: automobile exhaust, oil smoke pollution, as well as insect carcasses, bird droppings, resin, or fruit jam. The oil film is a layer of oily substance formed by various pollutants adhering to the surface of the car glass. This layer is extremely stubborn and generally difficult to remove. However, if not treated in time, it will inevitably affect driving. Causes of oil film formation: Automobile exhaust: Automobile exhaust can adhere to the car glass, forming an oil film. Oil smoke pollution: If oil smoke and dirt are not treated for a long time, they will form oil stains. Insect carcasses, bird droppings, tree gum, or fruit jam: Insect carcasses and bird droppings are highly corrosive. If not cleaned from the glass, they will adhere and harden, turning into an oil film. Methods to remove oil film: Use a dedicated oil film cleaner, spray the cleaner evenly on the glass, and clean and wipe it with a car wash towel or sponge. Use toothpaste for cleaning. Toothpaste contains abrasive particles that can have a grinding effect. Evenly applying it to the glass can clean the surface pores of the glass and remove the oil film. Use an eraser, car wash clay, or newspaper for wiping and cleaning. The eraser and car wash clay can remove the oil film, while newspaper has a certain oil-absorbing effect. Dipping it in water and wiping repeatedly several times can also remove the oil film.
