Can Tap Water Be Used as Windshield Washer Fluid?

[MaverickLee]

Tap water should not be used as windshield washer fluid because the mineral deposits in tap water can clog the washer nozzles, and it is prone to freezing in winter. The correct method for adding windshield washer fluid is as follows: 1. Open the hood and locate the windshield washer fluid reservoir; 2. Remove the cap and pour the windshield washer fluid into the reservoir; 3. Observe the fluid level until it reaches the marked line. The functions of windshield washer fluid include: 1. Cleaning performance; 2. Antifreeze performance, as it contains alcohol and ethylene glycol, which significantly lower the freezing point of the liquid; 3. Anti-fog performance, forming a monomolecular protective layer on the surface to prevent fog droplets and ensure clear and transparent windshield visibility; 4. Lubrication performance, as the ethylene glycol content provides viscosity, reducing friction between the wipers and the glass to prevent scratches.
