• How to Make Your Own Windshield Wiper Fluid

    Windshield wiper fluid is not an expensive product to buy from the store, but to reduce your wiper fluid cost even more, you can make your own at home with ingredients that you probably already have. It is a quick and easy process, and homemade wiper fluid can be better because you control the proportions of the ingredients used to make it.

    Materials Needed:

    • Water
    • Window cleaner
    • Alcohol or vinegar
    • Mixing sticks
    • A plastic bucket

    Step 1: Mix the Window Cleaner

    The standard amount of window cleaner to add is three cups per gallon of water. You can adjust this proportion as you become more experienced with making windshield wiper fluid. If you find later on that you need a little more window cleaner to get rid of the dirt that collects on the windshield, you can add more in future batches. Don’t add too much window cleaner or the fluid may leave streaks. Mix the solution thoroughly.

    Step 2: Add Alcohol or Vinegar

    To make sure the fluid doesn’t freeze, you can add alcohol or vinegar to it. Any kind of alcohol will work, as will any kind of vinegar. Just add about 8 fluid ounces of vinegar or alcohol to your fluid and stir it in thoroughly. As with the window cleaner, you can adjust this proportion as needed, with more alcohol or vinegar to fight more ice and frost.

    Step 3: Pour the Fluid in the Car

    To get the new windshield wiper fluid into the car so that it’s ready to use, find the windshield washer fluid reservoir under the hood. The windshield washer fluid reservoir is a clear plastic container, the cap of which should be marked with words or a symbol representing two spurts of water. Remove the cap and use a funnel to pour the fluid from the bucket into the reservoir. You can fill the reservoir all the way to the top. When you’re done, carefully replace the cap and close the hood.

    The price of store bought windshield wiper fluid is relatively low, but why not save a little extra and make your own? Making your own windshield wiper fluid allows you to adjust the proportions of the various chemicals to better fit your needs. If you live in an area where a lot of dirt and grime collects on the windshield, you may want to add a little more window cleaner. If you live somewhere cold where ice and frost is a frequent problem, you can add extra vinegar or alcohol as needed. This makes homemade windshield wiper fluid more convenient to use than a store bought product.
