When should the windshield washer fluid be replaced?

[McLucas]

There is no fixed interval for replacing car windshield washer fluid. Owners can typically check the fluid level and top it up as needed when it runs low. Below are detailed explanations about car windshield washer fluid: 1. Composition: Windshield washer fluid, commonly known as glass water, is a consumable in vehicle maintenance. High-quality windshield washer fluid mainly consists of water, alcohol, ethylene glycol, corrosion inhibitors, and various surfactants. 2. Cleaning performance: Windshield washer fluid is formulated with multiple surfactants and additives. Surfactants generally have functions such as wetting, penetrating, and solubilizing, thereby achieving the purpose of cleaning and removing dirt. 3. Antifreeze performance: It can significantly lower the freezing point of the liquid, thus providing antifreeze protection and quickly dissolving frost.
