Water VS Washer Fluid: What To Consider

Using water would be cheaper than buying washer fluid, but using washer fluid is often more effective. There are many types of washer fluids on the market for different purposes. Some are concentrates that require you to mix with water. It is always best, whether mixing or adding directly, to use distilled water to avoid gathering mineral deposits from tap water into the washer reservoir, wiper lines, or nozzles.

Cleaning Agents

Washer fluid typically contains detergent, a better glass cleaning agent than plain water, to improve visibility through the windshield. Stuck-on dirt on the windshield causes glare from the sun during the day and from headlights or other lights at night. A dirty windshield makes it very difficult to see and dangerous to drive.

Certain kinds of washer fluid can repel water, making it easier to see while you are driving in downpouring rain.

Other wiper fluids are good for cleaning bugs off the windshield. Anyone who has taken a drive through the country in the summertime knows how difficult it can be to clean bugs off the glass.


Make sure you have temperature-specific fluid in your vehicle if you go somewhere with below-freezing temperatures because both regular wiper fluid and water will freeze. Temperature-specific washer fluids contain ingredients that prevent the reservoir, wiper lines, and nozzles from freezing in cold weather. Check the label to see what temperature the fluid will freeze at, and check the weather to see how cold it is going to be. Some washer fluids freeze at zero degrees Farenheight, and others freeze at -27 degrees Farenheight.

If you do have to use water in an emergency, and you know there's a chance it might freeze, replace the water with washer fluid as soon as possible. When water freezes, it expands, breaking the windshield washing system's components, a potentially time-consuming and expensive repair. 

Environmentally Friendly

Certain chemicals, commonly used in washer fluid, are detrimental to the environment. Environmental awareness has led many people to start making their washer fluid by using water mixed with household ingredients. We've got great washer recipes on the way for you, just below.

Because consumers prefer environmentally friendly products, many washer fluid manufactures have stopped using harsh chemicals, such as toxic isopropanol alcohol, used as an antifreeze agent. If you want a safer option, we've got the best biodegradable washer fluid brands for you, listed later on.

What Is Washer Fluid Made From?

Windshield washer fluid contains a variety of toxic chemicals used to clean the glass and prevent the liquid from freezing. Each manufacturer makes its fluid with a different formula, but all types are similar. Most washer fluid is made from methanol, poisonous alcohol. Sometimes manufacturers add ethylene glycol, another kind of toxic alcohol. Different washer fluids have other ingredients based on the intended use. Formulas meant to withstand extremely low temperatures differ from formulas meant to clean bugs.

Can You Mix Washer Fluid?

It is not recommended to mix different kinds of washer fluids. Some fluids are concentrates meant to combine with water. Be sure to read the label before purchasing and using these products, so you know what you are putting in your vehicle.

Can I Make My Own Washer Fluid?

There are many different recipes for washer fluid alternatives made from household ingredients. Homemade washer fluid does not contain the harsh chemicals that all commercial fluids include. However, be aware that if you use a cleanser or detergent, you should check the label to identify any chemicals.

  • Mix one part white vinegar with three parts of water.

Can You Use Windex Instead Of Wiper Fluid?
