Sanco Industries Aqua Charge Windshield Washer Ultra Concentrate, 8 ounces makes 13.75 gallons finished product

Easily mixes with water. Super easy to use.

Very small bottle holding very concentrated washer fluid. The bottle isnt easy to pour and offers no means of measurement. A big eyedropper might be useful or a calibrated bottle that is easier to pour.

Should come with some type of measuring device.. Now lets see if it can make all those gallons..

Great Value

No directions included re proper dilution so it is a bit of guesswork. Also you MUST wear gloves unless you are exceptionally careful as the solution will most definitely stain your hands as I found out very quickly. You will also need to add deicer (some form of alcohol) for use in cold climate in winter. With those caveats it is a good way to make lots of washer fluid at at economical price.
