Can Mineral Water Be Used as a Substitute for Windshield Washer Fluid?
2 Answers
Mineral water should not be used as a substitute for windshield washer fluid because it can dilute the fluid, reducing its effectiveness and potentially damaging the windshield wipers. The correct method for adding windshield washer fluid is as follows: 1. Open the hood and locate the windshield washer fluid reservoir. 2. Remove the cap and pour the washer fluid into the reservoir. 3. Observe the fluid level until it reaches the marked line. Important considerations when adding windshield washer fluid: 1. Pay attention to the amount of fluid added; it is best not to exceed the MAX mark on the reservoir, leaving some space. 2. If using a concentrated windshield washer fluid that requires dilution, always read the instructions before use. Dilute the concentrated fluid properly before adding it to the reservoir. Open the reservoir cap in the engine compartment and pour in the prepared mixture. 3. Choose the appropriate windshield washer fluid based on your driving environment. In colder climates, opt for an antifreeze washer fluid. In southern regions, consider a fluid with insect repellent properties.
I think it's best not to add mineral water to the windshield washer reservoir. Once, when my car ran out of washer fluid, I poured some mineral water in a hurry. As a result, when driving in winter, the water completely froze, making it impossible to spray and clean the windshield. Later, at the repair shop, I learned that mineral water lacks antifreeze properties and would freeze and clog the nozzles and hoses below zero degrees, damaging the entire system. Washer fluid also contains cleaning agents that effectively remove oil stains, insect residues, and dust, ensuring clear and safe visibility. The minerals in mineral water can also precipitate into scale, shortening the water pump's lifespan over time. Since then, I've always bought bottled washer fluid—though it costs a bit more, it's worry-free. Regularly checking the reservoir is also a good habit to avoid similar issues. In short, dedicated products are designed more comprehensively to prevent minor troubles from turning into major repair costs.
