I usually don't have any fogging problems, but if I do, I just turn my oscillating floor fan on and it goes away.

I think this is something far too many people are paranoid about. If it helps.. my lenses are scratched beyond belief. One scratch goes from top to the bottom of the lens and is quite deep (not sure how that happened). Anyway.. you don't notice it a jot inside the rift and I stopped worrying about it. It will be obsolete soon anyway.
I found the fogging to be really bad on my CV1. The oculus lenses eventually warm up which helps a bit, but the main issue was coming from the nose gap. Warm humid air from my nose was coming back up through the nose gap and fogging both my glasses and the oculus lenses.
So I got some Sugru and modeled a sort of scuba style nose curtain that stops the warm air getting into the rift. Since I've had this, fogging is no longer an issue plus it blocks all the light leak that used to come from the nose gap.

Desk fan blowing toward me, no fog as long as it's on.
This.
Adjust the CV1 so its not super tight on your head.
I leave a little room in the nose area.
I put a small fan under a shelf I built on my desk. The fan stays on a lower setting and blows upward.
The wind enters the open spots near the nose areas and eliminates the fogging.
Use a dry wetwipe, spit on it, wipe across each lens...
