Can I Just Add Water When the Car Wiper Runs Out of Fluid?
1 Answers
You can add tap water when the windshield washer fluid runs out, but it should only be used as a temporary emergency solution. It is recommended to add dedicated windshield washer fluid. Since some residual washer fluid remains in the reservoir, diluting it can still provide some effect. However, you should not add mineral water or tap water every time, as even the most concentrated effective ingredients will eventually be diluted. Hazards of using tap water instead of windshield washer fluid: Ordinary tap water contains many impurities. Over time, these impurities can adhere to the rubber hoses, clog the pipes, and affect normal spraying. Long-term use of tap water or purified 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 adhered to the windshield. In winter, especially for car owners in northern regions, it is essential to switch to winter-specific windshield washer fluid promptly. Never use mineral water or tap water as substitutes, as water freezes at 0°C. Once frozen, not only will water fail to spray, but it may also cause the washer fluid reservoir and pipes to crack due to freezing.
