Should Windshield Washer Fluid Be Diluted with Water?

[DeLola]

Whether windshield washer fluid should be diluted with water depends on the type of fluid: 1. Ready-to-use liquid windshield washer fluid does not need dilution and can be directly poured into the reservoir; 2. Solid windshield washer fluid requires dilution, as it needs to be dissolved in clean water before use; 3. Highly concentrated liquid windshield washer fluid must be diluted with water in the correct proportion, as direct use can be too corrosive. Windshield washer fluid, short for automotive windshield cleaning fluid, mainly 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 providing cleaning and antifreeze properties.
