Windshield washer fluid in low temps?

If your camping in low temps in the teens or lower.
What would you suggest for windshield washer fluid?

I know windex will freeze.

I was thinking to help keep the windshield free of Ice/frost & driving through snow.
Besides letting the engine heat up long enough to defrost the windshield is there any sort of liquids you suggest for this?

My rig is a 12 Valve Cummins hot rod & has a 4" turbo back exhaust straight pipe.
So in other words it's loud & out of courtesy I try not to let it idle too long in campgrounds or where ever I may be before leaving.
Especially if we're leaving at sun up.

So...... That brings me to my question.


Thanks.
  • As a second home owner at Mammoth Lakes where sub zero temps are the norm in the winter I too was looking for WW fluid with the lowest freeze point I could get. For some strange reason, isn't it always in Calif. you cannot buy WW fluid with a sub zero freeze point in Los Angeles. I wanted to change before I left to go up and found out you just can't buy it here. Some auto parts stores will special order it but you have to buy a lot and they charge the devil for it.

    I have half a gallon if you really need some low freeze point fluid. If you can wait until you get to cold country and then buy some.
  • After being a mechanic in PA for forty years I never knew that there was something else to put in the washer bottle besides the blue antifreeze/fluid. Never gave a thought about the warm states. I know about the deicer or Rain X but around here it's sill antifreeze

    Temperatures around here can get down well below zero and all I use is the blue stuff all year around. I have never had issues with plugging up the nozzles or freezing. Have tried the deicer kind and never saw much difference.
  • So does the prestone work better than the rubbing alcohol.

    +1. I already drained the bug stuff and refilled the washer reservoirs with Prestone deicer. It'll even remove minor windshield ice on a frosty morning.
  • I doubt I could find de-icer in Los Angeles?

    Maybe I can order it on line?
    Yet seems alcohol would be easier?
    Considering I could buy it anywhere.

    So Rubbing alcohol works?

    Do you run it straight or mix it into windex?

    If I wait till I get to a cold weather area, I won't remember till I need it.
    & being I live in Los Angeles I doubt I could find any of this cold weather formula blends.

    So I was thinking of doing it at home before we head out.

    How much alcohol to what ever I'm mixing it with percentage wise?
    If I'm not running it straight?

  • Auto parts stores have washer solution with low freeze point, or winter blend.
