It really shouldn't need cleaning as a matter of maintenance like the old throttle bodies. At key-on, the throttle blade motor cycles a wipe of the bore with the blade for any restricting carbon build up.
An aerosol throttle body solvent can be used for bore/blade and vacuum fitting/port clean up, but avoid the throttle motor area.

I wouldn't move the throttle blade manually. They aren't meant to be. The scan tool may be able to actuate it wide open for test purposes.
I don't know if a helper pushing on the gas pedal with the key on will open it for you.
Is there an actual idle quality or stalling concern tied in with this ETC? If not, I would leave it alone.
You should be able to watch the blade sweep the bore at key on.

Techron makes good periodic fuel system maintenance.
