Windshield Washer Fluid

Fluids & Filters


Windshield washer fluid, or solvent as it's sometimes called, usually has a methanol base that gives the fluid its anti-freezing properties. Some fluids use isopropyl alcohol as the anti-freeze agent.


Windshield washer fluid is used for on-road, on-demand cleaning of the windshield through the electrically operated washers. Some vehicles also use a washer system for the rear window, and even the headlights.

Maintenance Tips/Suggestions

It's wise to keep the windshield washer reservoir full at all times with washer fluid. Running the system out of fluid can damage the windshield washer pump. Stay away from water, as it does not provide anti-freeze properties and does not clean as well as washer fluid. Some vehicles have multiple washer fluid reservoirs for different parts of the vehicle.

During the winter months where there is a lot of road salt, it's a good idea to keep a bottle of washer fluid in your car. If your washers stop working and the reservoir has plenty of fluid, have the washer system checked out at once by a professional service technician. Washers are a critical safety system of your car and should not be left neglected.
