Propylene Glycol

I've always been told to use RV antifreeze w/ propylene glycol. The other day I noticed that it's also in the deodorant I use. So I decided to look it up.

From Wikipedia:

We use a 30% mix of propylene glycol and over 30,000 gallons to cool the National Air and Space Museum in Chintilly VA. As of next month phase 2 will open and we will be using and additonal 15,000 gallons more to cool the extra 250,000 sq ft. We have 4 chillers and 2 of them are on line at any given time plus we make ice at night in our 27 thermal storage tanks then burn the ice during the day at peek temp during the Summer, we also call this our "ice farm". The color of our glycol is green not pink like RV antifreeze.
Propylene glycol is great as a none toxic antifreeze, but drops the efficiency of the chillers when used for cooling.

Funny how it is used in our everyday products, even in our food, and yet, some on here think it will contaminate their water system forever if they were to use it in their water lines. We can eat it, smear it on us, drink it, smoke it, brush our teeth, use it as mouthwash, ......... but we must never put it in the water lines of our camper. Funny, isn't it.

Especially since most of the folks I have camped with use bottled water for coffee, cooking, and drinking. The "potable" water is just used for dishes, wash water, and flushing.

Even as anal as I am, I do drink water out of the fresh water tank. I sanatize it every spring during dewinterization, and avoid using water sources other than my home water to fill the tank.......I know that will change when I start traveling for longer periods of time.

We don't drink ours but we make coffee etc with it. I suppose if one was real anal they could always add a small capacity UV filter.

The RV antifreeze I buy around here (Ontario, Canada) has ethyl alcohol (drinking alcohol) as its main ingredient . I guess they make the stuff so terrible tasting to prevent people from taking it to parties.

Camco's RV anti-freeze is available in Peterborough. When I was in Huntsville, I checked @ Wally Mart, Home Despot & Crappy Tire & the RV anti-freeze they all carried ethanol based anti-freeze.
