Does Automotive Windshield Washer Fluid Have an Expiration Date?

[McKevin]

Automotive windshield washer fluid does have an expiration date. Different brands of washer fluid have varying shelf lives, typically ranging from 2 to 3 years. Commonly referred to as "glass water," it is the colloquial term for automotive windshield cleaning solution and falls under the category of vehicle consumables. When purchasing washer fluid, first check whether it has exceeded its expiration date, and then inspect for any sediment in the liquid. The presence of sediment indicates that the washer fluid has deteriorated. While different brands have varying shelf lives, most washer fluids last 2 to 3 years. No matter how high-quality the washer fluid is, it cannot perform its function effectively once expired. Washer fluid is not just like tap water; it serves a cleaning purpose. High-quality automotive windshield washer fluid is primarily composed of water, alcohol, ethylene glycol, corrosion inhibitors, and various surfactants.
