Can Windshield Washer Fluid Remove Oil Film?

[LeJoy]

Windshield washer fluid cannot remove oil film. Here are the relevant explanations: Reasons: Because the cleaning and decontamination effects of windshield washer fluid on bird droppings, insect remains, and other dirt cannot be achieved by a mixture of dishwashing liquid and pure water (tap water). Moreover, windshield washer fluid also contains some lubricants, which can reduce friction between the wiper blades and the windshield. Oil film: For some novice drivers, this may be unfamiliar. Oil film comes from the exhaust pipes of vehicles ahead, especially buses and trucks emitting black smoke. If you follow too closely, oil film can easily adhere to the front windshield. Symptoms: During the day, it may not be noticeable, but at night when using the wipers with oncoming headlights, you may find the windshield covered with a hazy, patchy film that is unevenly distributed, with a net-like pattern in the middle. Additionally, rainwater forms irregular droplets on the windshield, severely affecting visibility.
