Grime, debris and dead bugs on your car's windshield can severely hurt your visibility behind the wheel. It is important to keep your car's windshield as clean as possible. The Lithia Toyota of Redding service team recommends that you should never attempt to substitute water for real windshield wiper fluid for the following reasons:

The biggest reason is one that will affect winter drivers heavily. Even if you do not reside in a frigid climate, chances are that you may soon take a holiday road trip to gather with loved ones in another state or region. Water has a much higher freezing point that real windshield wiper fluid, and it is no longer of use once it turns to ice. Real wiper fluid's freezing point is much lower, allowing it to get the job done even in the coldest of winters.
Windshield wiper fluid is also made with some extra ingredients that allow it to break up grime on the glass better than water. Water does not contain these same cleaning solvents and detergents. If you're a Redding, CA driver considering using water instead of real wiper fluid, then Lithia Toyota of Redding's staff wants you to reconsider.
