Can I Add Mineral Water to Windshield Washer Fluid?
2 Answers
You cannot add mineral water to windshield washer fluid. The specific reasons are as follows: 1. Mineral water lacks lubricating properties. Prolonged use will result in severe scratching of the car's windshield. Additionally, the friction between the wiper blades and the glass increases, leading to skipping and unusual noises during operation. 2. Mineral water naturally contains other components, which can produce sediment over time. Accumulated sediment may clog the pipes and potentially shorten the lifespan of the reservoir tank. 3. During winter or in extremely cold regions, the absence of the antifreeze properties in windshield washer fluid causes mineral water to freeze into ice. The subsequent expansion in volume (involving physics and chemistry) can crack the reservoir tank. Continuous use of the windshield washer switch under these conditions may easily damage the car's compressor.
I've been driving for over twenty years, and experience tells me that adding mineral water is not a good idea. The windshield washer reservoir is crucial for cleaning the front windshield, and dedicated washer fluid contains cleaning agents and antifreeze components, making it more effective against stains and extreme cold. Mineral water contains minerals that can lead to scale buildup over time, clogging the nozzles; its cleaning power is also inferior, failing to remove oily films during rain, which can impair visibility. Once, I forgot to bring washer fluid and used mineral water instead—during a summer rain, the windshield became blurry, nearly causing an accident. Dedicated washer fluid is affordable, costing just about ten yuan per bottle, and it prevents freezing and evaporation, ensuring driving safety. I recommend always keeping proper products on hand and not cutting corners.
