I believe RV antifreeze turns to slush when really cold but I'm not sure about washer fluid. I have some -22 washer fluid and I may leave it outside to see what happens.
I put a jar of -20 walmart WW fluid in my freezer a few months ago to see if it would freeze. Freezer is kept at 0. Nope, not even a little slushy, 100% liquid.
