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.
