Can Windshield Washer Fluid Be Replaced with Mineral Water?
2 Answers
Windshield washer fluid should not be replaced with mineral water. Below is an introduction to the functions of automotive windshield washer fluid: Cleaning Performance: Windshield washer fluid is formulated with various surfactants and additives. Surfactants typically have functions such as wetting, penetrating, and solubilizing, thereby achieving cleaning and stain removal effects. Antifreeze Performance: It can significantly lower the freezing point of the liquid, providing antifreeze protection and quickly dissolving frost. Anti-Fog Performance: A single-molecule protective layer forms on the glass surface. This protective film prevents the formation of fog droplets, ensuring the windshield remains clear and transparent with a clear field of vision. Anti-Static Performance: After cleaning with windshield washer fluid, substances adhering to the glass surface can eliminate static charges on the glass, providing anti-static properties.
A few days ago, I drove on vacation, and there was a lot of dust on the road. The windshield washer fluid was almost out, so I temporarily added some mineral water as an emergency solution. Soon after, the nozzles got clogged, and the fluid sprayed out in streaks, making it impossible to clean the windshield properly. Later, at the repair shop, the mechanic said mineral water contains minerals that can crystallize and clog the system, and over time, it can even corrode the pipes, increasing repair costs. Fortunately, he helped me drain it and refill it with proper windshield washer fluid. Now, every time it rains, the wipers clean the windshield perfectly, making visibility much safer. Don’t cut corners—mineral water really isn’t suitable as a substitute for windshield washer fluid. A proper bottle costs just over ten yuan, saving both money and hassle.
