What is Windshield Washer Fluid?
Windshield washer fluid is also known as washer fluid, screen wash, or just wiper fluid. This brightly colored liquid is used in motorized vehicles for cleaning the windshield while the vehicle is in motion.
Windshield washer fluid is a mixture of various chemicals, including methyl alcohol, water, colorant, an antifreeze ingredient, and some other optional ingredients like small amounts of polyhydric alcohols.
This fluid is stored in a dedicated plastic tank in the car, with a capacity of 0.75-1.5 gallons.
When it comes to cleaning the windshield, you can spray this liquid onto the windshield by operating a simple control.
The system features a small electric pump that sprays the liquid from the tank onto the windshield through a set of jets. These jets are designed to distribute the liquid on the windshield while the wipers clean off the dirt.
While most models only use this fluid to clean the windshield, others may use it to clean the headlights or the rear window as well.
