How to Remove Oil Film from Car Windshield?
2 Answers
Removing oil film from a car windshield can be done through the following methods: 1. Use a dedicated oil film cleaner, spray it evenly on the glass, and clean it with a car wash towel or sponge; 2. Use toothpaste for cleaning. Toothpaste contains abrasive particles that can polish the surface. Applying it evenly on the glass can clean the pores on the glass surface and remove the oil film; 3. Use an eraser, car wash clay, or newspaper to wipe and clean. An eraser and car wash clay can remove the oil film, while newspaper has some oil-absorbing effect. Dampening it with water and wiping repeatedly several times can also eliminate the oil film. If the oil film reappears shortly after removal, it might be an issue with the wiper rubber. It is recommended that the owner clean or replace it promptly.
Having driven for over a decade, what annoys me most is the oily film on the windshield, which gets blurry on rainy days. The simplest and most practical method is using toothpaste with a sponge—squeeze two centimeters of toothpaste onto a wet sponge, scrub the glass in circular motions for five minutes, then rinse off with clean water. Just do it occasionally when washing your car regularly. Park away from restaurant exhaust vents and under trees to avoid resin, and you'll have much less oily film. Never use laundry detergent or dish soap, as their high alkalinity can damage the glass coating. For stubborn oily film, use a professional degreaser with a polishing cloth—after scrubbing, the glass will regain clarity, making driving safer.
