What are the components of automotive windshield washer fluid?
1 Answers
Automotive windshield washer fluid is composed of water, alcohol, ethylene glycol, corrosion inhibitors, and various surfactants. In most vehicle models, the windshield washer switch is located on the right-hand control lever of the steering wheel. Pulling the lever toward the driver and holding it for a while will spray the washer fluid, and the wipers will also operate simultaneously. Some models have a physical button located on the steering wheel control lever, which activates the washer fluid when pressed. Performance of windshield washer fluid: Cleaning performance - Windshield washer fluid is formulated with various surfactants and additives. Surfactants typically have functions such as wetting, penetrating, and solubilizing, thereby aiding in cleaning and removing dirt. Antifreeze performance - It significantly lowers the freezing point of the liquid, providing antifreeze effects and quickly dissolving frost. Anti-fog performance - A single-molecule protective layer forms on the glass surface, preventing the formation of fog droplets and ensuring the windshield remains clear and transparent with a clear field of vision. According to usage environments, windshield washer fluid can be categorized into three types: summer-use windshield washer fluid, winter-use antifreeze windshield washer fluid, and special-effect antifreeze windshield washer fluid. Summer-use windshield washer fluid includes insect-removing adhesive components in the cleaning solution, which quickly removes insect residues from the windshield. Winter-use antifreeze windshield washer fluid ensures it does not freeze even when the external temperature drops below -20 degrees Celsius, preventing damage to vehicle components. Special-effect antifreeze windshield washer fluid remains unfrozen even at -40 degrees Celsius, making it suitable for use in extremely cold regions.
