How to Check if the Windshield Washer Fluid is Sufficient?

[RebeccaMarie]

Methods to check if the windshield washer fluid is sufficient: 1. If the windshield washer fluid is missing, a warning light will appear on the car's dashboard; 2. During normal use, if no washer fluid sprays out when using the wipers, it indicates a lack of windshield washer fluid. If there is no warning light, you can open the engine hood to check. The windshield washer fluid used in cars is mainly composed of water, alcohol, ethylene glycol, corrosion inhibitors, and various surface-active agents. It is important to note that if the car runs out of windshield washer fluid, tap water should not be used as a substitute. Windshield washer fluid serves a cleaning function, and its surface-active agents have cleaning and penetrating effects. Long-term use can improve the transparency of the glass and maintain its cleanliness.
