How to Remove Oil Film from Car Windows?

[OKevin]

You will need toothpaste. Apply toothpaste to the front windshield, spray water, and scrub vigorously. This method can remove at least 60%-70% of the oil film with decent results. Foam cleaner, a common automotive detailing product, can be sprayed onto the glass. Wait a few minutes, then wipe it with a machine for better results than toothpaste. Additional Information: Causes of oil film formation on car windows: 1. Vehicle exhaust: Incomplete combustion of gasoline produces various exhaust pollutants, which often accumulate on city roads, especially behind trucks, inevitably adhering to car windows and forming an oil film. 2. Smoke pollution: Frequently parking near restaurant chimneys will, over time, lead to the accumulation of smoke residue on the glass.
