I live in the peoples republic of California which prohibits VOC's in washer fluid outside of winter snow areas, so I make my own. I use a 1:3 dilution ratio of methanol to distilled water and then add a couple ounces of 2010 Products windshield cleaner concentrate (basically concentrated detergents and surfactants), plus my food coloring of choice (pink). The result is something that works better than anything you can buy off the shelf. Adding methanol does more than make the washer fluid freeze resistant - it also helps lift gunk off the windshield.
