DIY Streak Free Glass Cleaner

I have been making my own homemade cleaners for over 10 years now. It was one of the first things I did to eliminate toxins in my home.

Isn’t it crazy that something that is supposed to clean your home and make it better can actually cause major harm to your health?

I strongly believe that no matter how well a store bought household cleaner works, it is not worth using if it is filled with toxic chemicals!

Dangers of Household Cleaning Products

So many household cleaning products are filled with nasty chemicals and toxins. Some of these toxic chemicals can irritate the eyes and throat, cause headaches, cause respiratory problems and some have even been linked to cancer.

Windex is filled with some crazy ingredients that I don’t even know how in the world to pronounce.

  • Ammonium Hydroxide
  • Hexoxyethanol
  • Ethanolamine
  • 1,2-Propanediol, Monobutyl Ether
  • Sodium Dodecylbenzenesulfonate
  • Disodium Cocoamphodipropionate

According to the EWG the ingredients above can cause developmental / endocrine / reproductive effects, damage to vision, nervous system effects, skin irritation and so much more!

Environmental Impact of Household Cleaners

Then there’s the whole other issue of the environmental impact of using store bought household cleaners.

Many chemicals from toxic cleaners end up in the rivers and lakes. And of course, the bottles used to store household cleaners usually end up in landfills.

By switching to homemade cleaners rather than store bought you can help save the earth as well as your health and you can save money!

Beware of Store Bought “Natural” Cleaners

Making your own cleaners is so much cheaper than buying them from the store. Especially if you’ve been considering buying “natural” cleaners like Mrs. Meyers or Method.

Plus, you know exactly what’s in it. Because even so called natural cleaners aren’t quite as “natural” as they would like you to believe.

Check out the EWG rating for this popular tub and tile cleaner from Method. Or this countertop cleaner from Mrs. Meyer’s. They definitely are not the ratings I would expect from a brand claiming to be “natural” or “planet friendly”.

And quick disclaimer, I’m not saying all of the products from these brands are terrible. I’m just saying if you’re going to stick with store bought, please do your research.

The EWG has a super handy app that you can download on your phone. All you have to do is search the item or scan the barcode and it will give the item a grade based on its environmental impact as well as health concerns.

Natural DIY Glass Cleaner with Cornstarch

So like I mentioned earlier, I’ve been making my own cleaners for about 10 years now. My original glass cleaner recipe consisted of vinegar and water.

Yep, thats it.

And it worked. It wasn’t completely, 100% streak free. But it did the trick.

Then a few years ago I learned about the power of cornstarch. And it changed everything!

I don’t know the science behind cornstarch and its window / mirror cleaning super power. I honestly don’t care enough to look into it.

All I know is it works.

Frequently Asked Questions

Do I have to add cornstarch?

You don’t have to add cornstarch but it’s definitely the secret ingredient for a streak free finish.

Do I have to use filtered or distilled water?

I don’t trust the tap water where I live at all. Using distilled or filtered water ensures my homemade cleaners are chemical free. 

With that being said, if you’re not worried about the safety of your tap water, by all means use that instead.

  1. This is the best glass cleaner ever! I was a bit sceptical, given the corn starch but holy moly….it works like magic. Followed your recipe perfectly and it worked like a charm. It was also perfect for kitchen appliances…s/s steel fridge, microwave etc. Thank you for sharing your recipe.

    1. Arrowroot might work well as a substitute. It is similar to cornstarch. But I have never tried it so I don’t know for sure. If you try it, let me know how it goes!
