This No Streak Homemade Window Cleaner is super easy to make, is much safer than a lot of the store bought options, and leaves your windows and mirrors streak free.
Plus it costs almost nothing to make, so it's easy on the budget too.
I've been working for awhile to get and keep as many toxins as possible out of our home, and that includes household cleaners.
I personally think that it is so important to get Home Care and Personal Care products that are toxin free so that we, our families, and our world can be a lot more healthy.
Plus, you can save a TON of money by making these things yourself.
And it doesn't have to take a TON of time.
This Homemade Glass Cleaner Recipe is a case in point. It's simple.
Chemical Sensitivity
Since my childhood, I have been plagued with chemical sensitivities.
I've always been sensitive to a lot of things, but some chemical smells (think "off-gassing") and artificial fragrances are the worst.
For as long as I can remember, I'd get light-headed and feel "woozy" just walking down the detergent and house cleaner aisles at the grocery store, or walking through the perfume section in a department store.
Even walking outside when people are running their dryers bothers me. The VOCs in the dryer sheets are terrible for you.
So--for a long time, I've shunned the use of commercial home care products.
Since I'm a pretty simple gal about DIY cleaning products, mainly I was trying to get by with only vinegar and water. But sometimes you need something more.
Anyway, even if these chemicals don't make you feel bad, there's a lot of evidence that they aren't healthy, so it's a good idea to do what you can to remove them from your environment as much as possible. In fact, you really should do what you can to remove toxins from your life to improve your health.
Benefits of Making Your Own Homemade Glass Cleaner:
1. Get toxins out of your home and your life
Do you really want these things in your home?
propylene glycol
2 Hexoxyethanol
Ammonium Hydroxide
Mirapol Surf S-210
Viden EGM
Sodium C14-17 Sec-Alkyl Sulfonat
Fragrance Palette (all kind of stuff in there....artificial fragrances are not healthy)
Liquitint Sky Blue Dye
I didn't think so.
Yes, that is what is in one of the more popular glass cleaners on the market. Ick.
2. Save Money
You can make your own cleaner for way less money than you would spend on a commercial cleaner. Even if not, I would still prefer to make my own for the other benefits.
See the end of this post to see how much you can save.
3. Clean Up the Environment
Do you really want to add these toxins to our already toxically-overloaded environment? I am convinced that one of the main problems regarding the onslaught of autism, auto-immune disorders and cancer is the prevalence of toxins in our world. Every time you can use a toxin free product over a toxin laden one, you help the environment.
I used to use just plain vinegar to clean our mirrors and glass. Truth be told, we didn't really clean our windows often. Just didn't really think about it.
We'd put some plain vinegar on a piece of newspaper and wipe it all over the mirror.
It worked pretty well, but it did leave some streaks that were a little hard to get off.
This cleaner, however, is great. I found it on a number of sites all over the internet and I must say, it's a real winner.
This cleaner does contain isopropyl (rubbing) alcohol, which some people may wish to avoid, but I don't have a problem with that. I hope to try another recipe at some point without the isopropyl.
By the way, I discovered this recipe on several sites, so hard to know where it came from originally.
What Does the Cornstarch Do?
One of the things you'll notice in this formula for Homemade Glass Cleaner, is that it has cornstarch in it.
Are you with me in wondering what it's doing in there?
Here's what one reader shared with me:
On a microscopic level, glass is not perfectly smooth. When you spray water on it, the water molecules get caught in the pits on the glass surface. Water also clings to itself through hydrogen bonding – the hydrogen atoms from two molecules cling together. Water stuck in the glass + water stuck to more water = streaking. Cornstarch (or dish soap or oil-even a couple drops of essential oil) disrupts the hydrogen bonding, thus preventing streaks!
Cool beans! A DIY house cleaning recipe and science lesson in one!
How Much Can You Save Using this Homemade Window Cleaner?
A ton.
Vinegar: costs about $.59 for 32 oz at Aldi. So even if we double the price, let's say it costs $.04
Rubbing Alcohol: Based on current Rite Aid pricing (I called :-)!) $.25 for 1/4 cup
Cornstarch: A local Midwest grocery chain has it for $1.39 right now. If the Tbsp per pound info I got is correct, then the cost for 1 Tbsp is about $.04.
Water: I am just going to call this $0.00. The current approximate cost per gallon in my city is $.002 per gallon :-).
So - it costs a total of $.33 to make 2 1/2 cups of Glass Cleaner.

Tips & Notes for This Glass Cleaner:
Here are some helpful tips to ensure this works well for you.
- Shake well before using since the cornstarch might clog up your spray nozzle otherwise.
- Allergic to corn? I'm sure other starches like tapioca or arrowroot will work as well.
- You can use microfiber cloths or rags to wipe your surfaces clean. I prefer either those options or newspaper to paper towels since paper towels leave lint and are more wasteful.
- Label your bottle so as you make more and more non-toxic home cleaners you will know what is what :-). This handy dandy Chalkboard Contact Paper is great for label making.
- Color It: Add natural food coloring to the bottle so kids will know it's not water. Beet juice (from canned beets) is one inexpensive natural color or you could drop a bit of powdered beet juice in as well.
- Prevent Streaking: Some readers have had streaking issues. It's possible that this is from impure essential oils or hard water. If you have streaking issues, please do share in the comments what brand of essential oils you used and if you have hard water. I recommending only using pure essential oils even for house cleaning, because even though it's "just" for cleaning, you are breathing in the scent.
- Use Two Cloths
To avoid streaking, use two cloths--one to wash and one very dry cloth to dry.
- Eyeglass Warning: You can use this Homemade Glass Cleaner on your eyeglasses, but only if they are plain glass. If they are coated, avoid using this since alcohol will cause crazing (small surface cracks) in polycarbonate plastic. It can also cause the lens coating to deteriorate, resulting in less durable glasses that are easily scratched.
- Avoid Marble: Do not use this cleaner on marble as it be damaging.

Notes
Let me know what you think of this homemade window cleaner recipe!
The images in this post were updated in Jan 2020. For reference, here is a copy of one of the original images.
What do you use to clean your mirrors and windows?
what would the measurements of ingredients be in a smokers house or vehicle? because i tried this and it's greasy and streaky.
Oh my I don't know! Maybe you need to do it several times?
Has anyone tried hydrogen peroxide. Works wonders and no streaking. Just put some peroxide in a spray bottle and spray mirrors, car windows, house windows, etc. I use a microfiber cloth to wipe it off and it shines.
You know what works better than anything to clean windows and mirrors.....plain old hydrogen peroxide. Just pour some in a spray bottle and spray your mirrors and see how clean they will be, does not leave any streaks.
Interesting. What kind of cloth do you typically use?
I use a microfiber cloth. Mirrors and windows and even shower doors clean so well, never any streaks. My daughter has her own cleaning business and she tried it and that’s all she uses on any glass.
I clean my outside windows with; Hot water, a few drops of blue dawn dish soap, a old rag or sponge, a squeegee, an old dish towels.
Put a few drops of soap in maybe 4 c. of water, put your old rag in and somewhat wring it out but not alot. Wash you window and right away squeegee it off top to bottom. Each time wipe squeegee off when you get to the bottom with the old dish towel. Then just wipe the bottom of the window across with the dish towel.
Thanks! Glad you found something you like! I just prefer not to use things like Dawn. I wish I could find another option. I wonder if another more natural dish soap would work??

Sorry! I know this isn't YouTube, but I couldn't resist when I read "streaking issues".
My apologies.
I wanted to add to the list if I may. I've found that once I've gotten the glass clean, or so I thought, it can get even ten times better, however, this involves chemicals and is nowhere near being ecomnomical. However, the glass glows and is so soft after you apply this final step, it's hard to resist once you've tried it. It also repels water, already has oils in it to prevent streaking, and also works great on marble, granite, polycarbonate, mirror, all metals, polished fiberglass and really anything with a high gloss finish. Obviously, this is not a home made product, so I only use it maybe 5 times a year, or for special occasions. You can choose whatever kind you wanna buy, as I've yet to find one that will disappoint. My personal favorite is, NuFinish! The car detailing polish that is advertised as " the once a year car polish". The stuff is incredible! It's actually addictive it's so vibrant! I've heard that the 5 star hotels use this on every surface they can to give it that 5 star look, and it works. As a matter of fact, if you're in a hurry, and I don't suggest this as a solution at all times, because the point is to find a really good home made cleaner, and not a chemical, but just if you find yourself with only water and some car polish, don't even bother with the water. You can apply the polish, let it sit, wait for it to turn cloudy, or haze, and then simply wipe away the haze. It takes off everything, similar to rubbing alcohol, but generally speaking, it doesn't hurt any surfaces that I know of besides wood. It will bloat or impregnate softer woods, but other that, I can't think of anything else that it can't be used on, although, in sure there are more. Again, this diverts from the original idea. This is not at all cheap, has chemicals, and may cause irritation. I guess it all depends on how far you're willing to go to get invisible glass, and it is most definitely that after using NuFinish. To be honest, I've never even looked to see what all is in it. It could be even more harmless that originally thought, but the scent is fairly pungent, almost as bad as Brasso, but sweeter.
One other side note! For white teeth, and whiter whites when doing laundry, trying adding a 1/4 cup white vinegar, this is for laundry, not teeth), a 1/4 cup of baking soda, a tablespoon of coconut milk, and a touch of any citrus that is agreeable with you for tough stains or really dingy whites. Amazing! It works wonders on colors too! Especially white's!
Recipes for whitening teeth using these same ingredients can be found online, but just a word to the wise, when using this for teeth whitening, do not exceed more than once a week. The vinegar and citrus are both highly acidic and will remove healthy enamel from your teeth. I typically do 2 times a month and my teeth have never been healthier. My last dentist visit, I did this right before I went in, and when the dentist looked at my teeth, he was blown away at how clean my mouth was. He even said that my mouth was the cleanest he had ever seen .that is an awesome compliment to get from.your dentist, but had he seen me a week.later without the rinse, it's doubtful I would've gotten the same response. To keep the doctor away, I take a whiskey shot if Apple cider vinegar every 3 days. I haven't been sick since I started taking it 6 years ago. Eveypry 3 days is just right. Any more and you may suffer some gastrointestinal or esophageal issues. I recommend diluting it with water when you begin to see what you can handle first.
Thanks!
Super interesting! Why are you concerned about damage from diluted ACV in the esophagus etc??
I like this recipe! I've been using it for a year now - and it works so well! Thank you so much! I do have a question... Can I use denatured alcohol instead of the isopropyl alcohol?
Yes, pretty sure you can!
I've been using this for a couple of years and works better than the commercial ones! Thanks for posting!
So glad to hear that and you are so welcome! More coming soon. I'm so behind but determined to get more recipes, etc. out. Thanks for coming back to comment!
I tried this today with distilled water (I have hard water) and it still made a streaky mess. Then I tried to do it without the corn starch and had better luck but still not great. I have tiny dogs and small grandchildren so there are a lot of prints. I think I will go back to what my professional window washers use which is plain water and a drop of dish soap and use it with a squeegie instead of wiping. It seems to work well for them.
Hi there. So sorry that it didn't work for you! I am really confused about why this works fantastically for some and not for others. Will try to figure it out! Doesn't the method you are using end up using too much water?
Have you tried in on the inside of car windshield? I’m looking for a solution for that.
I haven't done that--but I can't imagine why that wouldn't work! Let me know!
Can u share the glass cleaning recipe that does not have alcohol in it and perhaps no essential oils too.?
Working on it--stay tuned! You can subscribe for updates if you like. I have a DIY Laundry Detergent coming soon too!
You claim to be research based but you didn't bother to find out whether or why vinegar damaged marble (instead of just taking someone's word for it.) Makes me pretty skeptical of everything on your website.
Hi ANne - thanks for reading. I'm really confused by your comment. I stated in the post the following "I've found out that you shouldn't use vinegar on marble as it can cause it to corrode"--why are you saying that I didn't bother to find it out? I did and the point was valid. I didn't just take someone's word for it.
Hope that helps. I am not perfect (like no one is) but I did research this and I research quite a bit of things and I suspect it's more than the average blogger. If you have other concerns, feel free to bring them up :).
Best glass cleaner ever! It works better than the commercially made glass cleaner. I love it when natural, good-for-you ingredients work better than the toxic stuff!!
I did use distilled water, because I had it on hand and it seems to work a bit better on my glass. Thank you for sharing your recipe!
Thank you! Working on another option too--you are so welcome!!
I always use this homemade recipe. I have a grandson that now lives with us and another on the way. I want to use natural cleaning DIY recipes as much as possible and this is the best for us! Thank you!
You are so welcome and glad to hear it!!
