I'd say it's the mist from the glycol, prolly not co2

..RV antifreeze could trigger it? Hadn't ever heard that, either. If that was the case, I'd have thought this would be a common issue that would happen all the time with winterizing, and folks would be talking about it more on forums like this. This is first time its ever happened for us, and I've been doing the winterizing thing myself for over 10 years.

Think I might do a search or two..
