How does car glass oil film form?
1 Answers
Automobile exhaust contains various pollutants emitted due to incomplete combustion. If frequently parked near restaurant chimney emissions and left untreated for a long time, thick oil stains will form. These deposits are highly corrosive. If not cleaned from the glass, they will adhere and harden, affecting the glass's light transmittance. Cars regularly parked under trees may accumulate tree sap and fruit residues.
