Can Tap Water Be Used for Windshield Washers?

[JayceLee]

Windshield washer fluid cannot be replaced with tap water. Tap water lacks cleaning properties and contains impurities that may clog the washer nozzles. Below are detailed reasons why tap water should not be used as a substitute for windshield washer fluid: 1. Especially in winter, tap water should never be used. Low temperatures can cause tap water to freeze. When liquids freeze, they expand, potentially damaging the washer fluid reservoir and, in severe cases, the rubber hoses. 2. During winter, always use a product with a sufficiently low freezing point. If the washer fluid's freezing point is too high, it may also freeze. 3. After refilling the washer fluid, always securely fasten the reservoir cap to prevent dust or impurities from entering. 4. If the washer nozzles become clogged, it is recommended to replace them with new ones.
