What kind of water should be added to the windshield washer reservoir?

[MacBethany]

Windshield washer reservoir should be filled with automotive-specific windshield washer fluid. The following are the functions of automotive windshield washer fluid: 1. Cleaning performance. The surfactants in automotive windshield washer fluid usually have functions such as wetting, permeation, and solubilization, thereby achieving the effect of cleaning and removing dirt. 2. Anti-freezing performance. The presence of alcohol and ethylene glycol can lower the freezing point of the liquid, thus providing an anti-freezing effect. 3. Anti-fog performance. A single-molecule protective layer will form on the glass surface, ensuring the windshield remains clear and transparent. The following are the steps to add water to the windshield washer reservoir: 1. Open the car's front hood and locate the blue cap behind the left headlight. 2. Find the white tube connected to a white jug-shaped object, with a fan-shaped symbol on the cap indicating the windshield washer. 3. Open the cap and add water directly. If there is not much foam, you can mix in a little dishwashing detergent.
