Zero-degree windshield washer fluid has a freezing point of 0 degrees Celsius and generally will not freeze in environments above 0 degrees Celsius. Types of windshield washer fluid: Based on antifreeze performance, it can be classified into summer-use windshield washer fluid, winter antifreeze windshield washer fluid, and special antifreeze windshield washer fluid. Based on form, it can be divided into solid windshield washer fluid and liquid windshield washer fluid. Liquid windshield washer fluid can further be categorized into concentrated (requires dilution) and non-concentrated types. Composition of windshield washer fluid: High-quality automotive windshield washer fluid mainly consists of water, alcohol, ethylene glycol, corrosion inhibitors, and various surfactants. Performance of windshield washer fluid: Cleaning performance: Windshield cleaner is formulated with multiple surfactants and additives. Surfactants typically have functions such as wetting, penetrating, and solubilizing, thereby achieving cleaning and stain removal. Antifreeze performance: The presence of alcohol and ethylene glycol significantly lowers the freezing point of the liquid, providing antifreeze effects and quickly dissolving frost. Anti-static performance: After cleaning with windshield cleaner, substances adsorbed on the glass surface can eliminate static charges on the glass, providing anti-static properties. Lubrication performance: Windshield cleaner contains ethylene glycol, which has high viscosity and can provide lubrication, reducing friction between the wiper and the glass to prevent scratches.
