Can I Add Mineral Water to Windshield Washer Fluid?

[DelIan]

You cannot directly add mineral water; you should use windshield washer fluid or washer concentrate. Ordinary mineral water contains many impurities, which over time can adhere to rubber tubes, clog the pipes, and affect normal spraying. The specific details are as follows: Hazards of Long-Term Use of Mineral Water: Long-term 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 clean dust superficially and lacks the ability to thoroughly remove dirt and insect residue adhering to the windshield. Winter Precautions: During winter, it is essential to switch to winter-specific windshield washer fluid. Never use mineral water or tap water as substitutes, as water freezes at 0°C. Once frozen, not only will it fail to spray, but it may also cause the washer fluid reservoir and pipes to crack due to freezing.
