Actually, I find just the opposite as nebfarmer. I used to winterize w/windshield washer fluid, but noticed crystal residue whenever there was some evaporation. I felt that RV stuff didn't do that...."here".
I wouldn't think folks with $300,000 pusher RVs would stand for "junk" in the water lines after winterizing.
It's the chem residue that makes "junk" . Hopefully I won't winterize mine for a month or more and I will be using it again in Feb I hope. Not much time to crystalize and I drain all of it out I can.
