Why does the windshield washer fluid not go down?

[MichaelFitz]

There are two possible reasons: first, there may be a lack of windshield washer fluid; second, the nozzle might be clogged. It is recommended to first check the windshield washer fluid reservoir. The functions of automotive windshield washer fluid include the following four points: 1. Cleaning performance: Windshield washer fluid is composed of various surfactants and additives. Surfactants usually have functions such as wetting, penetrating, and solubilizing, thus achieving the effect of cleaning and removing dirt; 2. Antifreeze performance: It can significantly reduce the freezing point of the liquid, thereby achieving an antifreeze effect and quickly dissolving frost; 3. Anti-fog performance: A single-molecule protective layer is formed on the glass surface, which can prevent the formation of fog droplets, ensuring the windshield is clear and transparent with a clear view; 4. Anti-static performance: After cleaning with windshield washer fluid, substances adsorbed on the glass surface can eliminate the charge on the glass surface, providing anti-static performance.
