Should Unused Summer Windshield Washer Fluid Be Replaced in Winter?
1 Answers
Whether to replace unused summer windshield washer fluid in winter depends on the local temperature conditions. If the temperature is below 0 degrees Celsius, it is recommended to switch to antifreeze windshield washer fluid. Introduction to Windshield Washer Fluid: Windshield washer fluid, also known as wiper fluid, is a type of cleaning solution for car windshields. It is primarily composed of water, alcohol, ethylene glycol, corrosion inhibitors, and various surfactants. Functions of Windshield Washer Fluid: Cleaning: Windshield washer fluid is formulated with multiple surfactants and additives, providing functions such as wetting, penetration, solubilization, and dirt decomposition, effectively cleaning and removing grime. Antifreeze: The alcohol and ethylene glycol in the fluid lower the freezing point of the liquid, not only preventing freezing but also dissolving frost. Anti-fog: The fluid forms a single-molecule protective layer on the glass surface, preventing the formation of fog droplets on the windshield and ensuring clear driving visibility. Anti-static: After cleaning the windshield, the substances adhering to the glass surface eliminate static charges, giving the fluid anti-static properties. Lubrication: The ethylene glycol in the fluid has high viscosity, providing lubrication to reduce friction between the wiper blades and the glass, preventing scratches.
