Do I need to add water when using windshield washer fluid?

[LeLondyn]

Windshield washer fluid does not require adding water when in use. Automotive windshield washer fluid comes in two types: concentrated and non-concentrated. The commonly used non-concentrated type is usually packaged in large bottles and is pre-mixed, requiring no dilution with water. The less commonly used concentrated type needs to be diluted with water and is typically packaged in small bottles, often referred to as wiper fluid concentrate, etc. The method of use is to first pour the wiper fluid concentrate into the car's windshield washer fluid reservoir, then add an appropriate amount of purified water for dilution. Windshield washer fluid is the common name for automotive windshield cleaning fluid and is a consumable in car use. It is composed of water, alcohol, ethylene glycol, corrosion inhibitors, and various surfactants, and has functions such as cleaning, antifreeze, antifog, anticorrosion, antistatic, and lubrication.
