Homemade Window Cleaner Using Cornstarch

Best Homemade Window Cleaner


I'm pretty sure I found the absolute best homemade window cleaner recipe ever, and can't wait for you to try it out!  I've used this homemade window cleaner for years, but it always takes awhile to mix up, and you really had to soak the windows to get a good clean window.


As y'all know, my husband's entire family is on his way for Easter, and when I realized just how filthy my windows were (seriously, gross), I decided to see what kind of window cleaner concoction I could hunt down. . . and this stuff is just amazing. Our house faces East, so the morning sun glares through the windows on the front of our home. Then in the afternoon the windows facing the back of the house  get the afternoon sun which don't leave any room for mistakes either. (It's awful ~ they look so pretty when they're clean but leave it to my kids to get them gunked up . . . argh!)


So, I spent about an hour scrubbing Sunday afternoon, and have the sunshiniest windows you've ever seen ~ plus I'm pretty sure I paid less than a quarter for all the ingredients, so this is a keeper at my house.


Here's what I used:

  • 2 cups water
  • 1/4 cup vinegar
  • 1/4 cup rubbing alcohol
  • 1 tsp. corn starch (I know, I know ~ it sounds so strange but it works!)
  • Recycled newspaper instead of rags for cleaning
  • Spray Bottle (I just used an old one I already had on hand)



  • Mix together all ingredients and pour into bottle
  • Label bottle and give it a good shake – then be sure to shake it occasionally to keep the corn starch from settling
  • Spray windows like you would using commercial cleaners, and use newspapers to wipe down
I'm not sure why the corn starch works, but it does . . . no idea why! If you have a few windows to scrub in your home, take a few minutes this week to get it done. I always put this at the very bottom of my to-do list, but when they're clean it feels so good. I'd love to hear if you have any other great tips for cleaning windows at your house!


By the way . . . we'll be skipping the five minute challenges this week as I've got my hands a little full around here, but if you all enjoy them they'll be back next week! The winner of last week's $10 Amazon gift card was kailinac…@yahoo.com. Thanks to every one who left a comment!

  1. I can’t wait to try this! I have everything on had too! Why newspaper? I usually use a cloth.

    • Hi Katie! The newspaper doesn’t leave any lint…. and cleans off beautifully (don’t know why, but it works!) It’s also free if you’re a couponer and already get the paper 😉

      I really couldn’t believe it worked so well, but they look great. Hope it works for you!

  2. I tried MULTIPLE homemade window cleaners last summer… UNTIL I tried THIS ONE!!! Don't let the ingredient of "cornstarch" scare you away. AWESOME! Will NEVER use anything else!!!

    I've had this recipe for a while hadn't tried it as I'm picky about the windows. With my glass top tables, I go through a lot of glass cleaner. Sounds as if I'm going to be saving even more money now. Thanks!
