Methods to remove oil film from windshield: 1. Use a dedicated oil film cleaner by applying it to the glass and then wiping with a car wash towel or sponge for effective cleaning; 2. Use toothpaste to remove oil film, as toothpaste contains fine abrasive particles that can polish the glass surface and eliminate oil film when rubbed; 3. Clean with dish soap, which contains hydrophilic and lipophilic components that emulsify oil and water, effectively removing dust, tree sap, or car wax. If the oil film reappears after some time, check if the wiper blades are contaminated with oil. If the wipers are not cleaned properly, cleaning the glass alone will be ineffective. Clean the wiper blades promptly or replace them if necessary.

When driving, the oily film on the windshield affecting visibility is quite annoying. First, try using commercially available car glass cleaner—spray it on, wait a few minutes, then wipe vigorously with a clean cloth. If that doesn’t work, switch to a mixture of white vinegar and water—just spray and wipe for an effective, cheap, and simple solution. Avoid wax-containing products to prevent leaving new oily residue. The oily film comes from air pollution or leftover car wax, making visibility blurry especially in rain. Regular cleaning is a strong preventive measure. Opt to work in a shaded area for safety. Keeping your windshield clear significantly enhances driving safety.

As a hands-on guy, I use household items to remove oil film. Spread ketchup all over the windshield and wait 10 minutes—the acidity dissolves grease. Then wipe it off with a damp cloth. Alternatively, mix baking soda and vinegar into a paste, apply it, scrub, and rinse with clean water. This method doesn't harm the glass and shows remarkable results. It reduces chemical use, is eco-friendly, and saves money. Reminder: Wear gloves during the process to avoid skin contact. Park away from trees to minimize grease buildup. This simple and efficient method is perfect for routine maintenance.

With decades of driving experience, I deal with oil film directly by spraying professional cleaner and wiping it a few times. If that doesn't work, I spray white kitchen vinegar on the glass and wipe it clean. It's effective without complicated tools, easily solving the problem. Cleaning the windshield ensures clear visibility and reduces accident risks. Regular car washing helps prevent it.
