How to Deal with an Oily Film on the Car Windshield?
2 Answers
Here are methods to remove the oily film from car glass: 1. Dishwashing liquid: Dishwashing liquid contains hydrophilic and lipophilic groups, which can dissolve oil and water, effectively removing oil stains. 2. Oil film cleaner: Spray the cleaner evenly on the glass and wipe it with a car wash towel or sponge for better cleaning results. 3. Toothpaste: Toothpaste contains abrasive particles that can polish the surface. Evenly wiping can clean the pores on the glass surface and remove the oily film. 4. Eraser, car wash clay, or newspaper: An eraser and car wash clay can scrub off the oily film, while newspaper has some oil-absorbing properties. Dampening it with water and wiping repeatedly can eliminate the oily film.
The oil film issue on the car's front windshield indeed affects driving visibility and safety. When handling it myself, I first rinse with regular glass cleaner to remove surface dust, then apply a specialized oil film remover spray. Wearing rubber gloves, I use a microfiber cloth to scrub in circular motions for three minutes, paying special attention to the driver's line-of-sight area. After rinsing, I noticed the aging wipers could cause secondary contamination, so I replaced them with new blades. Parking location is crucial - I make a habit of avoiding restaurant exhaust areas and tree sap drip zones. Using toothpaste as an emergency wipe every two months maintains clarity for about three weeks, though chemical residues may accelerate wiper deterioration. For best results, I recommend scheduled deep cleaning instead.
