What is the formula for automotive windshield washer fluid?

[ElizaFitz]

Automotive windshield washer fluid is primarily composed of water, alcohol, ethylene glycol, corrosion inhibitors, and various surfactants. Some high-quality washer fluids feature rapid snow and ice melting, anti-glare, and anti-fogging properties, playing a significant role in enhancing driving safety. The fluid possesses wetting and penetrating capabilities, effectively cleaning and removing dirt. It significantly lowers the freezing point of the liquid to provide anti-freeze protection. Additionally, it forms a monomolecular protective layer on the glass surface, which prevents the formation of fog droplets, ensuring clear visibility through the windshield. To add windshield washer fluid: First, activate the wiper switch to spray out the existing fluid from the nozzles below the windshield. When the nozzles stop spraying, open the washer fluid reservoir cap. Reactivate the wiper switch to expel any remaining fluid. Once confirmed that no more fluid sprays from the nozzles, pour in the appropriate amount of new washer fluid and securely close the reservoir cap.
