Windshield washer fluid cannot be used after its expiration date. Depending on the brand, the shelf life of windshield washer fluid varies, but it is generally around two to three years. Windshield washer fluid is made from deionized water and various environmentally friendly additives, providing functions such as cleaning, antifreeze, antistatic, and anti-corrosion. Some higher-quality windshield washer fluids also offer features like rapid snow and ice melting, anti-glare, and anti-fogging, which significantly enhance driving safety. Windshield washer fluid should also have protective properties for the windshield and wiper blades, safeguarding and maintaining the vehicle during normal use. Some brands of windshield washer fluid are formulated with multiple surfactants and additives, uniquely capable of repairing minor scratches on the windshield surface by forming a protective film to ensure comprehensive care for the windshield.
