I ran out of washer fluid this morning. So I went into the trunk for the gallon that I bought last autumn. Open the top, nothing comes out. Nothing. I look at the label in amazement, and whadayaknow:

FREEZE PROTECTION TO +32.

You can't make this stuff up.

Thats what happens to H20/blue coloring and a drop of soap. You can add up to 30% yellow bottle heet to get it to around -20F per gal. As sold at $0.99/ gallon it may be more profitable than Soda, if not very close.

The orange RainX is the best. Good to -40F I believe (I've used it that low) and if you use it the rain will bead on your windshield.

“Let's take a drive into the middle of nowhere with a packet of Marlboro lights and talk about our lives.” ― Joseph Heller, Catch-22

Same here. Sacramento County outlawed traditional windshield fluid so almost all is "+32 F", i.e. water + blue dye. The exception is I have seen motor home "winter fill" suspiciously close on the shelves, and it says something like "-30 F". I just fill my cars w/ 1 gal distilled water + 1 pint of rubbing alcohol from the dollar store. I like the wintergreen one since the green dye insures I didn't forget a pint. Not just the cost, but I worry that if the fluid freezes it could damage parts, and I doubt the County would reimburse you. Alcohol is a fairly natural substance, so not sure what the environmental concern is.

Washer fluid in the standard states contains Methanol. Methanol is toxic to humans. California decided the danger of kids drinking washer fluid is too great and therefore they don't trust you to buy real washer fluid.

Vodka is way more expensive than rubbing alcohol though! At least the kind I drink. Even the cheapest nastiest vodka would still be $.

I never drank or ate anything that wasn't food... Maybe I had vigilant parents, I'm not sure.

Such is the way with Cali. A custom concoction will work just as good though.
