Anyone ever use windshield washer fluid for winterizing??? The stuff says it's good for -20 degrees and is 1/3 the cost of the pink antifreeze. I've tested the windsheild washer fluid and it stays liquid down to 0 degrees, no slush at all. Going to test with 25% water mixture to see if it still stays liquid at 0 degrees.
We might hit 0 degrees a time or two at best throughout the winter, usually we never see 0. I'm in the mid PA. area.
I'm winterizing now with the pink stuff, but just got to thinking about how using windshield washer might make this less expensive as I use about 15 gallons. Just a thought.
