What is Automotive Glass Grease Film?
1 Answers
Automotive glass grease film refers to a layer of oily impurities adhering to the glass, primarily originating from sources such as vehicle exhaust, cooking fumes, insect remains, bird droppings, tree resin, fruit jam, and other external contaminants. During the use of automotive glass, small pores gradually develop over time. These pores absorb external impurities and pollutants, thereby forming a grease film. Moreover, automotive grease film is difficult to remove. Using wipers with windshield washer fluid only makes the glass increasingly blurry and can refract light, impairing visibility. This is because the grease film contains impurities like dust, tree sap, or car wax, and ordinary windshield washer fluid has limited cleaning effectiveness. Toothpaste can be used to remove the grease film, as it contains abrasive particles that provide a polishing effect. When using toothpaste to clean the grease film, it's important to apply the right amount of pressure and wipe evenly to better clean the glass surface pores and eliminate the grease film. Using an eraser, detailing clay, or newspaper can also be effective. Newspaper has some oil-absorbing properties, and dipping it in water to wipe repeatedly several times can clean the surface. Detailing clay works similarly—it's economical and effective but more time-consuming and labor-intensive. A more professional approach to removing grease film from glass is to use a dedicated grease film cleaner. Spray the cleaner evenly on the glass, then wipe it with a car wash towel or sponge for excellent cleaning results.
