Rain-X, by the orange gallon. Don’t need to use much. Not so good at cleaning off mud though. Great for all else.

I just tried out Rain-X wiper fluid and am very impressed. I dilute wiper fluid 1:1 with water by volume. I live in south Texas and don't need to worry about the making the freezing point 40 below zero.

I especially appreciate the clearer vision through the windshield at night when it’s raining.

By use, I am referring to how often to run the squirters. I don’t dilute it, but only use ~a gallon+ per year.
