While we are on this subject,,why cannot I find the concentrate for RV or windshield wash?I once got a 5 gallon concentrate of RV base,it would make almost 30 gallons at -40F,I got it free from old plumber.WE buy concentrated farm chems always,,makes no sense on these two to buy the water.
I don't think those numbers work, not looking it up at the moment. Livestock farmers might have pure propylene glycol around, but I don't think that's burst proof at -40 at that dilution. RV antifreeze is PG, cheap stuff is more ethyl alchohol (which you can remove from E85 if you have cheap access), and corrosion inhibitors. Just buy it for what it costs in the big box stores.
The old plumber probably had boiler antifreeze, which does come concentrated and with excellent inhibitors usually, but it can't be more than 100%. |
Cheapest place to get antifreeze for sprayers in bulk
