Where to Add Windshield Washer Fluid for GLC?

[Keith]

The windshield washer fluid for Mercedes-Benz GLC should be added in the engine compartment. Mercedes-Benz offers two types of windshield washer fluids: one commonly used in summer, which contains insect-removing agents to quickly eliminate insect residues on the windshield; and another specifically designed for winter use, an antifreeze-type windshield washer fluid, mixed in a 1:1 ratio to ensure it does not freeze even when the external temperature drops below -20°C. When adding windshield washer fluid, the following precautions should be noted: Professional windshield washer fluid must be used for cars and cannot be replaced with tap water. This is because windshield washer fluid not only cleans but also has anti-static and lubricating functions. In winter, it also provides antifreeze and anti-fog effects, which tap water cannot achieve. If you are in the wild and run out of windshield washer fluid, you can temporarily use mineral water as a substitute. Although mineral water is still far inferior to windshield washer fluid, it is better than tap water as it contains no impurities. Windshield washer fluid has the following properties: Cleaning performance: Windshield cleaner is composed of various surfactants and additives. Surfactants typically have functions such as wetting, penetrating, and solubilizing, thereby aiding in cleaning and removing dirt. 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-fog performance: A single-molecule protective layer forms on the glass surface. This protective film prevents the formation of fog droplets, ensuring the windshield remains clear and transparent with a clear view. Lubricating performance: The ethylene glycol in the windshield washer fluid has high viscosity, providing lubrication to reduce friction between the wiper and the glass, preventing scratches. Anti-corrosion performance: The windshield cleaner contains various corrosion inhibitors, ensuring no corrosion to any metals, and is absolutely safe for car paint and rubber.
