Can Windshield Washer Fluid Be Replaced with Mineral Water?

[AllieMarie]

Windshield washer fluid should not be replaced with mineral water. Windshield washer fluid is designed to clean the windshield, provide anti-static properties, prevent fogging, offer lubrication, and resist freezing. Using mineral water would dilute the washer fluid, potentially causing various adverse effects on the vehicle and even shortening the lifespan of the wiper blades. Mineral water lacks lubricating properties, and prolonged use can lead to severe scratching of the windshield, increased friction on the wiper blades, and operational issues such as skipping and noise during use. Windshield washer fluid, commonly referred to as windshield cleaning solution, is a consumable automotive product. High-quality windshield washer fluid is primarily composed of water, alcohol, ethylene glycol, corrosion inhibitors, and various surfactants.
