Can I Add Tap Water When the Windshield Washer Fluid Runs Out?
1 Answers
Windshield washer fluid cannot be replaced with tap water. Windshield washer fluid serves the following functions: 1. Cleaning properties: Windshield washer fluid is formulated with various surfactants and additives. Surfactants typically have wetting, penetrating, and solubilizing functions, thereby achieving cleaning and stain removal. 2. Antifreeze properties: The presence of alcohol and ethylene glycol significantly lowers the freezing point of the liquid, providing antifreeze effects and quickly dissolving frost. 3. Anti-fog properties: A single-molecule protective layer forms on the glass surface. This protective film prevents the formation of fog droplets, ensuring the windshield remains clear and transparent with unobstructed visibility. 4. Lubrication properties: Windshield washer fluid contains a high viscosity ethylene glycol, which provides lubrication, reducing friction between the wiper and the glass to prevent scratches.
