Cleaning Performance: Windshield washer fluid is formulated with a variety of surfactants and additives. Surfactants typically have functions such as wetting, penetrating, and solubilizing, thereby achieving cleaning and stain removal. Anti-freeze Performance: Windshield washer fluid contains alcohol and ethylene glycol, which significantly lower the freezing point of the liquid, quickly dissolving ice and frost to prevent freezing. Anti-fog Performance: Windshield washer fluid forms a single-molecule protective layer on the glass surface, which prevents the formation of fog.
