Windshield Washer Fluid - Ultra Concentrate, 1 Quart Makes 55 gallons Finished Product (1)

I won't be buying overpriced window washer for a long time. This stuff works really well, and does not leave a color streak on my Pearl White paint. I'll add a little methanol for our light winter, when the time comes, but for now, a tiny bit more than half an ounce + a gallon of RO* water = happy camper. * Note: I use an RO due to very hard water. No matter how good any product, if you use it with hard water you will not get satisfactory results. I have used others, but this 2010 Pro-Formula is the best.

This little bottle makes 55 gallons. I maybe use two gallons of washer fluid in the family vehicles over the course of a year. That’s two plastic jugs, two trips to the auto parts store, two different semi-trucks hauling pallets of 99% water across the country. I’m set for the next 25 years with this one purchase.It’s a proven product, no dyes or stains, just simple efficient cleaning.

What is it that folks in the Northwest know about keeping a clean windshield in the drizzle, rain, and splashing of road grime?This has always been ”our little secret” for spotless windows in extreme conditions.Extremely inexpensive and highly effective, this solution works and can be tailored for every season, whether it is used with tap water (mix about 2/3 ounce per gallon in spring, summer, or fall.)Or in winter by adding to conventional windshield antifreeze in the same volume.We add to methanol in the winter for best results.

20/10 is hands down the best windshield washer fluid you can buy. It cleans the road grime off of your windshield and wipers and has antifreeze in it so it works in colder weather. It is the only Windshield Washer Fluid I will put in my vehicles. I went to a Jiffy Lube and they filled my windshield washer fluid well with some other stuff and I had to drain it all out and fill it with 20/10. I now tell anyone working on my vehicles not to touch the windshield washer fluid.

At about 0.8 oz. per gallon, it will last a looooong time. Cleans windshield well, but did not get rid of some long dried on bugs. I was not sure if the product would damage water level sensor or pump in the GMC. Emailed company and they responded with alacrity, assuring me that the product was safe. I do not need washer fluid in Florida, so I just mix a little less than an ounce of product in a gallon container and use as necessary.

I purchased to save on all the plastic used to have 1 gallon windshield containers used. I have hard water, therefore if I don't want my windshield system in my car to get clogged up I would have to purchase plastic containers of distilled water unless I am able to find a refillable source of distilled water.

I have always loved this product. Probably the best windshield cleaner on the market. Unfortunately hard to find now days because of the other brands on the store shelves. Those brands are JUNK with respect to 20/10. The cost is a little more but the quality is a lot better. . Never streaks, oil and road film gone. Even cuts bug debris from the windshield. I have used this product for many, many years. Always great results.

It does work better than most of the cheap blue dyed washer fluid. Cuts through dirt and road grime no problem. Being clear, it can be hard to see how much is in a car's reservoir.
