DIY Homemade Window Cleaner

There is nothing like the look of freshly washed windows, especially when there are no smudges on them.

The light just seems to shine in more brightly when the windows are really clean.

DIY homemade window and glass cleaner.

Many homemade products do just as good a job as those the retail products that you buy in stores.  Things like disinfectant wipes and liquid soap can be made at home for a fraction of the price of store goods.

Washing windows with store bought window cleaner such as Windex can have the cost add up, even if you use the refill, so I decided to see if I could come up with a decent DIY window cleaner recipe.  (affiliate link.)

This recipe has just a few ingredients: vinegar, water, rubbing alcohol and cornstarch.  I’ve used vinegar in so many other household ways, but vinegar and water on its own left my windows a bit too streaky.

The rubbing alcohol gets rid of that problem and the cornstarch is naturally abrasive so it helps to cut down on the grime that windows can get.

The recipe could not be any simpler.  You will need these ingredients: (affiliate links)

  • 2 tbsp rubbing alcohol
  • 2 tbsp white vinegar
  • 1 cup of water
  • 1 1/2 tsp of cornstarch


Mix all of the ingredients in a spray bottle and shake well.  Spray on any window or glass surface and wipe clean with a soft cloth or paper towel.  (I find newspapers are great for cleaning windows.  My grandmother used to use them and they leave the windows very streak free.)

That’s all there is too it.  You can have clean and streak free windows for pennies.  Just be sure to shake the bottle each time before you use it. The cornstarch will settle to the bottom of the bottle between uses. 

TIP:  use a label on the bottle and write the recipe so you will remember it.  If your memory is like mine, you will forget it when it’s time to make it again!
