Is your CO detector a combo CO and Propane detector? The propane detector is really a flammable vapour detector so any combustible hydrocarbons will set it off. Since you said that you poured antifreeze into the drains and if the detector is near the floor and anywhere near the drain it will set it off. The pink antifreeze that is safe for metal pipes will more likely set off the alarm more than the antifreeze for plastic pipes only as they contain a higher concentration of volatile hydrocarbons Once the volatiles dissipate then you should be good for the rest of the winter.
the detector is a combo, detects both CO and Propane.
..Now that I'm thinking about this...This is only 2nd time winterizing the RV we have now, as we bought it in March 2012. Last year when winterizing, the CO detector was disconnected, as it had gone bad a few weeks before and was going off non-stop. I got it fixed a few weeks after that.
Soo, this is first time winterizing this RV (Motorhome), with the CO detector hooked up and working as it should. And, indeed, it (detector) is at floor level, just a few feet away from the shower stall, where I poured a good bit of antifreeze down to protect the traps.
OK, so this may well have been vapor from the pink stuff, and not actual CO pulled in from the garage. That being the case, though, seems there's not really much I can do about it, except to just live with it when winterizing, or relocate the detector (not worth it).
Still, I would have thought if RV antifreeze could cause this, we'd have seen a LOT more posts from other folks having the same issue when they winterize.
