Can Windshield Washer Fluid Be Replaced with Mineral Water?

[VonAugust]

Mineral water should not be directly used as a substitute for windshield washer fluid or washer concentrate. Ordinary mineral water contains many impurities that can accumulate in the rubber pipes over time, leading to clogged pipelines and affecting normal spray function. The details are as follows: 1. Hazards of Long-Term Use of Mineral Water: Prolonged use of tap water or mineral water may increase friction between the glass surface and the wiper blades, causing scratches on the glass. Moreover, plain water can only remove dust superficially and lacks the ability to thoroughly clean dirt or insect residues on the windshield. 2. Winter Precautions: During winter, it is essential to switch to winter-specific windshield washer fluid. Under no circumstances should mineral water or tap water be used as substitutes, as water freezes at 0°C. Frozen water not only prevents spraying but may also cause the windshield washer reservoir and pipelines to crack due to freezing.
