The kind of commercial windshield washer fluid that is so convenient to buy at the store contains methanol. Methanol is extremely poisonous and is dangerous to breathe or touch. Less than a half of a teaaspoon can cause blindness and less that two ounces can kill a person.
On top of the dangers to the people using it, it causes environmental damage, by leaking onto the ground when we spray our windows with it. It also gets into the air as pollution. Billions of gallons of this washer fluid ends up in the environment every single year.
Here are directions for making your own windshield cleaning solution fluid.
Shake this all up in a jug, and then let the bubbles go down and pour into your windshild washer fluid canister to the fill line. Please mark the container with the ingredients so it will be easy to remember how to mix it up.
Another mixture is the following for during the times when you don't really have freezing weather to deal with:

I am looking for a formula for warm weather windshield-washer fluid. Can anyone help?
By Al
I think any natural cleaner for windows would work on auto glass too. Personally, I would make a solution of half isopropyl alcohol and half water.
When I used the windshield washer system on my car last winter (ice condition weather), the water on the windshield became ice very soon. Now what kind of alcohol can I mix with water and at what percent?
By Mori from Tehran
In the States we can purchase windshield washer fluid that won't freeze in the winter. Check and see if you can find something like that where you live.
When the winter is coming, and along with the cold comes having to scrape the car windows every morning. That is a serious pain for us, considering I am height challenged. I have a difficult time reaching the center of the windshield.
Surfing the net looking for de-icing solutions, I came across some reader tips on The Dollar Stretcher. Here is some of helpful suggestion for this problem.
1. To place 3 parts vinegar and one part water in a spray bottle, spray the windshield and all the windows and mirrors before you go to bed at night, and in the morning you should have ice free windows. You can also use rubbing alcohol if you don't have any vinegar.
2. To use two parts rubbing alcohol to one part water, and you should have no more ice.
3. To place a lightweight tarp or an old sheet over your car, and any ice buildup should quickly melt away. Sometimes this doesn't work though, because where I live, we get too much snow for lil ole me to just pull off the tarp with all the snow on it.
4. To mix rubbing alcohol and a few drops of dish liquid. Spray the windshield and in a few minutes, the ice will lift right off. Makes scraping much easier.
There are usually two kinds of washer fluid, summer formula which is good for dissolving bug guts, and winter formula which does not freeze. If you have below freezing temperatures, you should be able to purchase this. If it is not readily available, ask the store where you shop to order such a product for you. Obviously, if it is needed, many people will buy it.
I find methylated spirits does the trick for my windshield washing as to what strength just keep trying till you find the right mix our winters here in the UK are not as harsh as the USA.
Regular rubbing alcohol will work fine if added to washer antifreeze that is not strong enough. Add about 6oz.
I need a good, non-streak, washing liquid for the windshield of my car. Not for the windshield washer, this is so I can wash the inside and outside of my windshields and not have a film or streaking.
By Mary from Irvine, CA
We have always used just a small amount of non-sudsing ammonia in a bucket of warm water, and a microfiber cloth to clean the windows in the autos, and home. Be sure to wear some gloves, and keep a window open for fresh air, as ammonia is irritating to most people.
I know I sound like a broken record, but I use white vinegar for cleaning anything and everything. It will definitely cut grease. If it is being used on something I am not sure of, I try a small patch, and then rinse it well.
For the outside, just use water, or dish soap or Mr. clean or similar in water and a squeegee. For the inside, I use Windex and a towel.
Use any window that does have any ammonia. The spray can is the best.
Use baby shampoo and water . We use it to clean windows completely before tinting them. Works like a charm
Will adding Dawn dishsoap to the windshield washer fluid help cut the winter grime from windshield? How much do you add?
By Papa from Blackstone, MA
I would not add any Dawn dish washing soap to the windshield fluid. First you will get a lot of bubbles and soap film. Second, there will be a build up of soap scum in the small hoses that run from the fluid reservoir and then the washes will not work until the hoses have been replaced. You don't need to add alcohol as the washer fluid is a combination of water and alcohol. If you want to clean the windshield with Dawn mix some up in a pail with water and use a squeegee by hand.
I agree, do not add dish detergent to you windshield fluid! You could damage a lot of parts and end up costing more than a lifetime worth of buying windshield fluid! Buy yourself a squeegee like they have at the gas station, and just clean your windows periodically. If you are out driving, and the car is warm, just toss some clean snow on the windshield before you get out, run the wipers, and that helps, too.
Be sure to clean the wiper blades themselves to get a nice clean windshield.
I DISAGREE!!! AS LONG AS YOU ONLY USE A TINY AMOUNT OF DAWN IT WILL NOT CAUSE ANY PROBLEMS! I USE IT ALL OF THE TIME IN MY OWN VEHICLES' WINDSHIELD WASHER/WIPER FLUID. I MAKE MY OWN WINDSHIELD FLUID AND HAVE USED THIS IN ALL MY VEHICLES FOR YEARS! FOR 2 GALLONS OF WINDSHIELD WASHER FLUID I USE 2 CUPS OF RUBBING ALCOHOL , 2 CUPS WHITE VINEGAR AND 1/4 TEASPOON OF BLUE DAWN DISH LIQUID ADD WATER TO THIS MIXTURE TO MAKE 2 GALLONS.
I LIVE IN NORTH CAROLINA AND WE DON'T HAVE A LOT OF SNOW AND ICE. IF YOU DO LIVE IN AN AREA WHERE SNOW AND ICE IS AN ISSUE YOU CAN SUBSTITUTE THE CHEAPEST VODKA AVAILABLE FOR THE RUBBING ALCOHOL OR YOU CAN JUST ADD A CUP OR SO OF CHEAP VODKA TO THE BASE RECIPE.
I DON'T HAVE ANY SOAP SCUM BUILD UP IN MY WINDSHIELD WASH FLUID CONTAINER. THE ALCOHOL AND THE VINEGAR PREVENT THAT HOWEVER I NEVER USE ENOUGH DAWN LIQUID DETERGENT TO CAUSE SUCH AND ISSUE!
When making the windshield wash fluid is there something I can put in it to make rain drops roll of like Rain-X?
You need a little silicone oil in the mixture. Here is a recipe. itstillruns.com/
I know there are lots of great recipes online, but when I talked to my mechanic about this a while back, he strongly recommended NOT making any kind of homemade windshield fluid EVER.
I wanted to do it to save money and because I learned about the the dangerous chemicals in them (super bad for people and the environment.
He said that he has seen the homemade kind freeze up in the winter and crack the thing that holds the fluid and that is a big expense to repair it. He also saw people who had the stuff FREEZE on their windshield in the winter and cause accidents because they could not see when it flash froze. That one scared me really bad.
I trust him implicitly so when he gave me this lecture, the store kind won.
I am still not happy about the chemicals so I just learned to use the stuff very sparingly.
I clean my wiping my windows with a clean rag and water if I see it is dirty before leaving home. That doesn't help when I am driving and need it, so I only give it one squirt, do not hold it down and spray. Usually that does the trick. If not, I give it one more quick squirt.
Just my 2 cents worth...safety first for me and cars...I drive an 11 year old car and I need it to last another 11 or more years...so I made this compromise! Thanks for listening!
