Can Potatoes Remove Oil Film from Car Windows?
2 Answers
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.
As a seasoned DIY enthusiast in the garage, I've tried using potatoes to remove glass oil film. Cutting a raw potato slice and rubbing it on the car window, the starch particles can absorb some grease, making the glass appear slightly cleaner, but the effect is short-lived and not durable. After wiping, I often find a thin layer of starch left behind, which becomes blurry and harder to see when it rains. In fact, car glass oil film comes from the accumulation of road oil and exhaust fumes, which is highly stubborn. Relying solely on home remedies like potatoes won't do the trick. I suggest using soapy water or alcohol cotton balls for emergency treatment, and for daily maintenance, it's better to use professional glass cleaning sprays like Rain-X to ensure clear and safe driving visibility. Remember, unresolved oil film issues can cause glare at night, posing a significant risk. Don't compromise safety to save money.
