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.

  • 1 gallon of water
  • 1 oz. dish soap
  • 6 oz. rubbing alcohol
Rubbing alcohol acts as kind of an antifreeze for your windshield while driving.

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:

  • 1 gallon of water
  • 8 oz. of glass cleaner
Here is a mixture for cleaning your windows at home in the house. Put the following in a spray bottle and spray onto a window and wipe off with a clean rag using long back and forth motions.
  • 2 quarts water
  • 2 Tbsp. white vinegar
  • 1 tsp. dish soap
  • 1/2 cup rubbing alcohol

    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. I use this for windows, glass tables and mirrors.

    Also, after paying 3.97 at Walmart, I found the same thing at the Dollar Tree. I also found brake fluid, transmission fluid and power steering fluid.

    Once you compare the ingredients, you will find they are all the same. Good Luck. PBP

    Where your car is concerned, you are better off buying something that is made for cars. Go to a discount store and get something inexpensive and buy several jugs. It's ok if it is for winter use, the only thing about it is that it won't freeze. Get it on sale and you will have enough to last through the winter which is when you use the most.

    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?

    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.

    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.

    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.

    Thank you.

    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. So far I've been completely satisfied.

    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.

    Frost-Free Windshields

    Vinegar will help keep windshields ice and frost free. When a car has to be left outside overnight in the winter, coat the windshields with a solution of 3 parts white distilled vinegar to 1 part water. A good tip for frost free windshields is believe it or not shaving cream. Rub it in good and wipe off when it starts to fog up, then reapply. You can also use the above tip with alcohol instead of vinegar; I like the green kind best. (04/08/2010)

    Does anyone have a "recipe" to make your own freeze-proof windshield washer fluid?

    God Bless.

    By Sheila from Springfield, IL

    Answers:

    Homemade Windshield Washer Fluid

    Yes, its very easy to make. If you look at the ingredients of store bought windshield washer fluid, it uses methanol alcohol. You can't really buy that off the shelf, but you don't need to. Basically you need to add ammonia and/or isopropyl rubbing alcohol to your recipe to keep it from freezing.

    What I do is take a gallon jug, add water until its about 2/3 full. Then I add any kind of window cleaner. I open the window cleaner and pour some of it in. If it's winter time and you are afraid of it freezing, add a bottle of some type of rubbing alcohol. I only add the Windex so it's blue.

    You can just use rubbing alcohol and mix that with water. Most rubbing alcohol is about 70 or 80 percent strength. So personally I would add say 16 ounces to 48 ounces of water and mix.

    The whole purpose of making it yourself is to save money over buying it, so keep that in mind. (02/22/2010)

    Does anyone have a recipe for homemade soap for windshield washers?

    In New Zealand we don't have the extreme cold temperatures. A tip one of the mechanics told me that I have used that works well, is adding baby shampoo to the window washer. It is much milder than ordinary detergent, maybe you could use that in the summer. You don't need very much.

    I also live in Colorado, and what I do to save is simply dilute regular washer fluid with water. With most of the stuff that gets on your windshield from the road, almost straight water works fine. The point of the alcohol in the store bought stuff is to reduce the freezing point, not as much for its cleaning ability.

    So with that said, the amount I dilute depends on what month it is. In January and February, I add little water, in summer time I've used almost straight water. But I usually don't go quite that far. The mix is somewhere in between for the rest of the months. My car is garaged at night, so it stays a smidge above the outside temp. (01/24/2007)

    What about vinegar and water? (05/03/2007)

    By

    Homemade Windshield Washer Fluid

    Option one: 70% water to 30% non sudsing ammonia. Non sudsing clear ammonia leaves no residue or detergents on your windshield. Ammonia won't freeze like water, either. It won't damage your hoses or wipers over time. You may want to toss in a few ounces per gallon of vinegar as a fortifier. Vinegar will break down grime and also leave no residue. And it is a great deodorizer, not like you need deodorizer on your windshield, but only to beak down grime. The ammonia is what, something like a buck a half gallon. (08/23/2007)

    I use menthynol 50%, water 50%, and a few drops of dishwashing detergent. (09/21/2007)

    By S Durf

    Homemade Windshield Washer Fluid

    Here's how I used to do it, back in the days when Big Lots had 16oz bottles of 70% Isopropyl for a dollar. Not sure if it's still profitable, the cost of the alcohol is the worst part, by the time it gets to $2 a bottle we're talking 50 cents just in this for mix.

    Also you need a big bottle of dish wash detergent like Dawn, but that's too expensive so get the cheapest brand you can find. Big Lots is good for this also, though the best I found was at Dollar General.
    You need to calculate the cents per ounce, a good price is 4 cents per ounce or lower, so if it's a 24 ounce bottle it should cost no more than 96 cents.

    Then you need some 1 gallon jugs, save your milk containers and anything else that fits 1 gallon, you want to make this stuff 4-6 or more gallons at a time or it's not profitable.

    Then, the formula:

    • 1 oz of dish washing detergent
    • 1/3 of a bottle of 70% isopropyl OR 1/4 bottle 90%
    • The rest water.

    Yes, eyeballing is OK, but watch it with the soap.

    This works great, not sure how freeze resistant it is, but it's way better than store bought washer fluid. Have I used it?
    I have been making it like that for 4 years now. (11/14/2007)

    For a washer fluid to not freeze in temps down to -40 C, the mixture would need to contain almost 70% methanol. This makes the mixture not only very flammable, but also very expensive for those without access to industrial chemical suppliers, where methanol can be purchased for considerably lower prices.

    Be careful what you mix. I added Joy detergent and vinegar to my purchased blue fluid to help cut the grime of the windshield salt, here in Minnesota. Within a week I replaced the windshield wiper pump. It was frozen up. Another week, I replaced the rear window pump; it too was frozen. When was the last time you heard of these failing? I assume this mixture degraded the seal on the pump, and the fluid migrated into it. (01/07/2008)

    I am up here in Montreal. Snow, ice and -35 are not uncommon. Because of our dependency on WWF, it sells for about 3$ a gal. That may on a good week last 3 to 5 days. Hence the motivation to look for the home brew.

    I found a manufacturer who has in his web site the formulas for about 5 grades of cleaner. The wetting agent they add in very small amounts helps to reduce streaking. As a old school photographer, the term wetting is well known and was used to the same end on film. A very cheap and concentrated product called "Photoflo". Hope this helps. Info site: recochem.com

    By Chris

    Homemade Windshield Washer Fluid

    I have determined the actual formula for a popular
    premium washer fluid:

    % by Weight

    • 35% Methanol (wood alcohol)
    • 63% water
    • 2% automotive antifreeze(also colors the fluid)

    I have used this for many years with excellent results. Good to at least -40F.

    The key is methanol; the heavier alcohols such as Isopropyl require much higher percentages to work.
    You have to use about 70% by weight for 90% Isopropyl to have the same effect, the cost is too high.
