Can I Add Plain Water to Windshield Washer Fluid?
1 Answers
Plain water should not be added to windshield washer fluid because their compositions differ. Therefore, tap water cannot be used as a substitute for windshield washer fluid. If your vehicle runs out of windshield washer fluid, you should promptly replace it with new fluid. Functions of windshield washer fluid: 1. Cleaning performance: Windshield cleaner is formulated with various surfactants and additives. Surfactants typically have wetting, penetrating, and solubilizing functions, effectively removing dirt. 2. Antifreeze performance: The presence of alcohol and ethylene glycol significantly lowers the freezing point of the liquid, preventing freezing and quickly dissolving frost. 3. Anti-fog performance: A single-molecule protective layer forms on the glass surface, preventing fog droplets and ensuring clear visibility. 4. Anti-static performance: After cleaning with windshield cleaner, substances adsorbed on the glass surface eliminate static charges. 5. Lubrication performance: The ethylene glycol in the fluid has high viscosity, reducing friction between wipers and glass to prevent scratches. 6. Anti-corrosion performance: The fluid contains multiple corrosion inhibitors, ensuring it is completely safe for all metals, car paint, and rubber.
