No-Streak Homemade Window Cleaner

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.

Our environment is filled with toxins and one of the biggest offenders in the toxin department is household cleaners.

So I’ve been working for awhile to get and keep as many toxins as possible out of our home.

I make and use homemade foaming soap, a natural dishwasher rinse aid, homemade “soft scrub” and even soap nuts instead of laundry detergent.

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.

In fact, most of them are lickety-split.

So even uber busy folk can do this and not drive themselves crazy.

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.

Truthfully, I’ve always been sensitive to a lot of things, but some chemical smells (think “off-gassing”) and artificial fragrances are one of the worst.

For as long as I can remember, I would 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 smell of the VOCs in the dryer sheets is just terrible (and terrible for you).

So–for a long time now, I have 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 is 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.

Either way, making your own DIY Glass Cleaner is a breeze.

Benefits of Making Your Own Homemade Glass Cleaner:

1.  Get toxins out of your home and your life

Let me ask you this–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.  Let’s do what ever we can, within reason, to help clean things up for us and for future generations.  Every time you can use a toxin free product over a toxin laden one, you help the environment.

Now, 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 would 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.

But in a pinch, it works well.

This cleaner, however, is great.  I found it on a number of sites all over the internet and I must say, it is a real winner.
My son likes to take our spray bottle all over the house and clean all the windows and mirrors –it helps to have a bottle with a blue top (his favorite color!)

This cleaner does contain [easyazon_link identifier=”B00ZCCYTWG” locale=”US” tag=”whnemo-20″]isopropyl (rubbing) alcohol[/easyazon_link], which some people may wish to avoid, but I don’t have a problem with.  I’d love to hear your thoughts on that….and I did find another promising recipe that costs quite a bit more money to make and has no isopropyl alcohol.  Maybe I’ll give it a whirl!

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. Huh?

Are you with me in wondering what it’s doing in there?

Well, this update is just in today (Sept. 13, 2013) from a reader who is “in the know.”  Here is her answer:

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.

Cost of a popular brand on the market? [easyazon_link identifier=”B000093INI” locale=”US” tag=”whnemo-20″]$3.43 on Amazon[/easyazon_link].  I had to do some fancy math to get the cost per ounce, but this is what it costs for 2 1/2 cups (20 oz).  So you save over 90%!

TIPS & NOTES for this DIY Glass Cleaner:  

Before you try making this Homemade Window Cleaner, here are some helpful tips to ensure it 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.

– Make sure to label your bottle so as you make more and more non-toxic home cleaners you will know what is what :-).

– Another great tip from a reader: 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. I think that would work great..

– This handy dandy Chalkboard Contact Paper is great for label making.

– 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. Thanks! I recommending only using pure essential oils even for house cleaning, because you breathe in the fumes from the cleaning products and you don’t want to be breathing in impurities.

Use Two Cloths

Another tip from a reader–to avoid streaking, use two cloths–one to wash and one very dry cloth to dry.

Eyeglass Warning

You can definitely 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 poly carbonate plastic. Additionally, it can also cause the lens coating to deteriorate, resulting in less durable glasses that are easily scratched.

Homemade Window Cleaner

Ingredients

• 1/4 cup white vinegar (apple cider vinegar will work as well)
• 1/4 cup isopropyl (rubbing) alcohol
• 1 Tbsp non-GMO cornstarch (the cornstarch reduces streaking -- anyone know why?)
• 2 cups water
• 8-10 drops essential oil of choice (optional. Lemon, orange, or another citrus would be my choice here, but lavender or others would be nice as well. Go here to learn why I chose this company as having the best essential oils for the money.)
• A good glass spray bottle or quality BPA-free plastic spray bottle.

Instructions

• Combine everything in a spray bottle. (You can reuse the container you already have from your store bought glass cleaner.  I had to buy one at a dollar store since we haven't used glass cleaner in years :-)!)
• Shake well to mix.
• Spray onto glass surface and wipe clean.

Notes

I heard from a reader that vinegar can damage marble, so be careful using this around / on marble surfaces.
