Can I Make My Own Wiper Fluid?

To answer your question about homebrew windshield wiper fluid, we will look at what the purpose of have the windshield washer system is.  Windshield wipers were initially invented before automobiles became popular and widely owned.  Windshield wipers have obvious advantages for safety and gave early automobiles the ability to be operated in any type of weather.   However windshield washers did not come as standard equipment initially and was actually first offered as an aftermarket option in the 1930s.  Windshield washer systems were created to help clear dust and derbies from a dry windshield during normal operation.  Today, windshield washing systems are even more critical as our vehicles travel at impressive speeds allowing for bugs, road dirt and dust to become quickly stuck onto the windshield obscuring vision and making for dangerous driving conditions.  Some of today’s cars have even better windshield washing systems that can deliver heated washing fluid to the windshield to better clear dust and dirt and help melt ice in the colder months.

Since windshield washing systems have a variety of functions, so the windshield washing fluid must perform a variety of tasks:

Windshield Washer Fluid Functions:

  • Dissolve dried on deposits
  • Clean away bugs and road grit
  • Resist freezing
  • Resist foaming so it can be easily pumped
  • Dry quickly once windshield is cleared
  • Lubricate wiper blades to avoid scratching windshield
  • Not leave any streaks or fog on the windshield

It would be difficult using household products to create a mixture that will accomplish all of these tasks without compromising in another area.  For example, putting pure water in your windshield washer reservoir will lubricate the wiper blades and may clean away dirt but will not dissolve dried deposits and could easily freeze in the system which could destroy your fluid reservoir a

pump.  Also, adding water with a small amount of soap in it could leave your windshield foggy and difficult to see through and has the potential of creating foam in the reservoir making the mixture difficult to pump and dispense to the windshield.

Simply letting your windshield washer fluid reservoir run dry is a dangerous option especially in the winter.  The most economical way to keep your windshield washer fluid reservoir full is to use BlueDevil Windshield Washer Concentrate to make your own.  One 16oz bottle of BlueDevil Windshield Washer Concentrate will make up to 16 gallons of washer fluid.  If you purchase BlueDevil Windshield Washer Concentrate directly from the manufacturer online, it cost less than $0.45 per gallon! In many states, the chemicals used to clear the roads of snow and ice can easily and quickly cloud your windshield making travel impossible and likely dangerous.  Even during warmer months, you never know when you will be following a truck that is spilling sand and dust, or a car that is leaking oil or antifreeze.  There are many situations that can quickly obscure your vision that you need to be ready for.
