Does windshield washer fluid have an expiration date?

[LenaLee]

Windshield washer fluid does have an expiration date, and the shelf life may vary among different brands, but it is generally 2 or 3 years. Here is some information about windshield washer fluid: 1. High-quality windshield washer fluid is made from deionized water and various environmentally friendly additives, featuring functions such as cleaning, antifreeze, antistatic, and anti-corrosion. Some premium washer fluids even offer additional benefits like rapid snow and ice melting, anti-glare, and anti-fog properties, which significantly enhance driving safety. 2. If the washer fluid has expired, it is recommended not to use it. No matter how good the washer fluid is, once it expires and deteriorates, it loses its intended effectiveness. 3. Therefore, when purchasing washer fluid, car owners should first check whether the product is within its expiration date, and secondly, look for any sediment in the fluid, as its presence indicates that the washer fluid has deteriorated.
