How to Remove Oil Film from the Inside of the Windshield?

Methods for removing oil film from the inside of the windshield: 1. Use various brands of specialized oil film removers available on the market; 2. Alternatively, use solvents such as windshield washer fluid or soapy water for rinsing; 3. Canned spray-type oil film removers are highly effective. Simply spray for about 3 seconds within the wiper's coverage area to remove the oil film. To prolong the intervals between oil film remover applications, it's essential not only to remove the oil film from the glass but also to clean the oil film from the wiper blades. Apply the oil film remover to a cloth and wipe the surface of the wiper that contacts the glass. When excessive oil film affects visibility, be sure to stop and wipe it off, as using the wipers alone won't suffice.
When I noticed an oily film on the windshield, I immediately realized it would affect driving visibility, especially during rainy days or at night. Later, I sprayed 70% medical alcohol on a clean microfiber cloth and gently wiped the inner surface of the glass, which quickly removed the oily film. The whole process took about 10 minutes. Remember to operate with the vehicle turned off to avoid accidents. Usually, the oily film may come from evaporated car perfume or greasy food residues, so I recommend regularly cleaning the glass surface—wiping it every two weeks can prevent buildup. Additionally, placing some activated charcoal bags inside the car to absorb odors can also reduce oily film accumulation.
To tackle the issue of oil film inside the car, start with simple DIY methods. Mix white vinegar and water in a 1:1 ratio, pour it into a spray bottle, and spray it on the interior glass. Use a soft cloth to wipe in circular motions until the oil stains disappear, then dry with a clean cloth to avoid water marks. I found that using old newspapers for final polishing works best—not only does it remove oil, but it also leaves no fiber traces. This method is cheap and eco-friendly, using materials you already have at home. Remember to open the windows for ventilation during the process to avoid strong vinegar smells. For daily driving, avoid spraying air fresheners or smoking inside the car to prevent oil film from recurring.
