You don't say quite how big your GH is or how far you intend to move it but with the glass removed and safely stored the two of you could probably lift and move the aluminium frame complete, they are surprisingly light. If you can enlist the help of a couple of volunteers it will make it easier. My wife & I moved a 6 x 8 model about 10 feet like that a while ago. Tape the door shut if you don't remove it though, because it's really annoying if it slides about as you walk.
I'm not sure about using a jet washer to clean the glass although they use them on cars etc with no ill effect. I can only suggest trying one pane to see how it stands up.
