Can Potatoes Remove Oil Film from Car Windows?

[MacZane]

The claim that "rubbing car windows with potatoes can remove oil film" is inaccurate. Using potatoes to clean windows merely covers the oil film with a layer of starch, and this coating is not stable—it can be easily wiped away, rendering it ineffective. Below is relevant information: Introduction to oil film on car windows: After prolonged driving on the road, oil mist emitted by the car can form a layer of oil film on the windows over time. Methods to remove oil film: Apply some dishwashing detergent used for cleaning dishes onto the glass, spread it evenly, and then rinse with clean water. The oil film will be removed along with it. For stubborn oil film, multiple cleanings may be necessary. Alternatively, purchase a specialized oil film cleaner and follow the instructions for cleaning. Oil film cleaners will coat the glass with a protective layer after cleaning, preventing rainwater and other debris from adhering. Replace the windshield wiper blades if the oil film cannot be completely removed. In such cases, the oil film may have already adhered to the wiper blades, making it useless to clean the oil film from the glass alone. If this occurs, the wiper blades should be replaced promptly.
