Should the windshield fluid be drained in sub-zero temperatures?

In sub-zero temperatures, it is necessary to promptly replace the windshield fluid with an antifreeze type. The cleaning, antifreeze, antifog, and antistatic properties of windshield fluid are as follows: Cleaning performance: Windshield fluid is composed of various surfactants and additives. Surfactants typically have functions such as wetting, penetrating, and solubilizing, thereby achieving the effect of cleaning and removing dirt. Antifreeze performance: The presence of alcohol and ethylene glycol in windshield fluid can significantly lower the freezing point of the liquid, thus providing antifreeze effects and quickly dissolving frost. Antifog performance: Windshield fluid forms a monolayer protective layer on the glass surface. This protective film can prevent the formation of fog droplets, ensuring the windshield remains clear and transparent with a clear field of vision. Antistatic performance: After cleaning with windshield fluid, substances adsorbed on the glass surface can eliminate the charge on the glass surface, providing antistatic properties.
