Methods to deal with oil film on the car's front windshield are: 1. Use an oil film cleaner to wipe it off; 2. Apply dishwashing liquid with a cloth to wipe the oil film area; 3. Apply baking soda toothpaste, then wipe with a wet newspaper; 4. Clean the glass with soapy water; 5. Replace the wiper blades. The reasons for oil film on the car's front windshield are: 1. Car exhaust and asphalt dust stick to the windshield surface and turn into oil film; 2. Oil stains enter the wiper fluid reservoir when filling it, and when spraying the wiper fluid, the oil stains adhere to the glass, forming an oil film; 3. Worn wiper blades leave water marks after wiping, which form an oil film.
