What temperature rating is used for car windshield washer fluid?

[StephenLee]

Car windshield washer fluid is generally divided into 0°C fluid for summer use and -20°C or -35°C fluid for winter use. Functions of windshield washer fluid: It has capabilities such as dirt removal, water repellency, antifreeze, antistatic, and corrosion prevention. It can effectively remove dust, lubricating oil, gasoline/diesel residues, polishing wax residue, tree sap, bird droppings, and insect residue on highways. It can quickly disperse rainwater on the windshield, preventing blurred vision for drivers during heavy rainfall. It can neutralize the electric charge generated by friction between the windshield, wipers, and substances in the air, enhancing the conductive effect on the glass surface to resist static electricity and prevent dirt adsorption caused by electric charge, which could affect visibility. Precautions for windshield washer fluid: In winter, be sure to completely drain the existing fluid before refilling with antifreeze windshield washer fluid.
