How to Deal with Oil Film on Car Windshield?
2 Answers
Dealing with oil film on a car windshield requires different methods depending on the extent of the oil film. Methods for treating oil film on car windshield: For small areas of oil film, dishwashing detergent can be used for localized cleaning. For larger areas, specialized glass cleaners or oil film removers can be applied. First, rinse off dust with water, then apply the cleaner to a cloth and remove the oil film in a circular motion. The wiper blades can also be cleaned at the same time, and finally, wipe everything clean. Causes of oil film on car windshield: Vehicle exhaust contains various pollutants from incomplete combustion. Frequent traffic congestion in urban areas, especially when driving behind trucks, can lead to oil film buildup on the windshield. Consider periodically applying a coating to the glass. It’s not necessary to visit a specialized car care center; you can purchase a coating agent yourself, spray it on the glass while washing the car, and then wipe it dry with a cloth. Functions of the windshield: It helps reduce interference and effects of crosswinds; prevents raindrops, dust, and other small particles from entering the car; and upon impact, the glass shatters into small, blunt-edged pieces, minimizing harm to passengers and providing a safer space.
After driving for so many years, it's quite common for the windshield to get oily films, mainly caused by road grease and exhaust residue. When I see this, I first rinse the surface with water to remove large dust particles, then dilute some neutral dish soap with water and scrub the glass with a soft cloth. For particularly stubborn oil films, I use a specialized degreaser spray and then wipe carefully. Remember to use a clean towel or sponge to wipe in straight lines from one side to the other, not in circles, to avoid leaving water stains. If the oil film isn’t removed, headlights will reflect at night, making it hard to see, and it’s even more dangerous in the rain, increasing the risk of accidents. Washing the windshield every two weeks regularly prevents oil buildup. If all else fails, go to a car wash for help—they use high-pressure water guns for a faster, professional clean. Safety first, don’t cut corners. Taking care of these small details makes driving much more pleasant.
