Do I Need to Add Water When Refilling Windshield Washer Fluid?

[SanMiranda]

Whether you need to add water when refilling windshield washer fluid depends on the specific type of fluid: 1. Ready-to-use liquid windshield washer fluid does not require dilution and can be directly poured in; 2. Solid windshield washer fluid needs to be mixed with water—simply dissolve it in clean water before use; 3. Highly concentrated liquid windshield washer fluid must be diluted with water in the correct proportion, as the undiluted liquid is highly corrosive. Windshield washer fluid, also known as windshield cleaning fluid, primarily consists of water, alcohol, ethylene glycol, corrosion inhibitors, and various surfactants. Based on its form, windshield washer fluid can be categorized into solid and liquid types, both of which offer cleaning and antifreeze properties.
