What is automotive windshield washer fluid made of?

[DelAurora]

Automotive windshield washer fluid is primarily composed of water, alcohol, ethylene glycol, corrosion inhibitors, and various surfactants. Windshield washer fluid, also known as car windshield cleaning liquid, is a consumable product in automotive use, featuring functions such as dirt removal, antifreeze, antistatic, and corrosion prevention. Some higher-quality washer fluids also offer rapid snow and ice melting, anti-glare, and anti-fog properties, playing a significant role in enhancing driving safety. Inferior quality washer fluids are mostly diluted with water and alcohol, which not only damages the gloss of the car's paint and the hardness of rubber strips but can also cause color differences or swelling in rubber or other plastic parts in severe cases.
