How to Remove the Oil Film on the Windshield?

You can sprinkle a little flour to absorb the oil before wiping it off. Wiping directly with a towel can clean it immediately. You can cover the windshield with toilet paper or tissue, then spray with car cleaner.
When I notice oil film on the windshield, I often use kitchen ingredients to deal with it. Prepare strong tea and vinegar in a 1:1 ratio, mix them in a spray bottle. First, wipe off the surface dust on the glass, then evenly spray the mixture onto the oil film areas. Wait for two to three minutes, then scrub vigorously in circular motions with a sponge. Pay special attention to the lower edge and the wiper working area, as those spots tend to have thicker grease buildup. Finally, rinse thoroughly with clean water—the result is just as good as using specialized cleaners. Doing this casually after each car wash helps prevent oil film accumulation. For severe oil film, I wrap used tea leaves in a soft cloth and use the solution to polish the area again.
I have plenty of experience with removing oil film. The key is choosing the right cleaner—make sure to buy a dedicated glass degreaser with abrasive particles. Avoid working under direct sunlight, as hot glass will cause the solution to evaporate too quickly. First, spray the cleaner and let it sit for 1 minute, then use a damp nano sponge to wipe in one direction (no back-and-forth scrubbing to avoid scratches). Rinse with a high-pressure water jet to wash away oil particles. Here’s a detail most people miss: 90% forget to clean the wiper blades! Oil residue stuck to the rubber will just smear back onto the glass, undoing all your effort. After treatment, test with a newspaper—if the print blurs after rinsing, there’s still residue.
