I had a leaking rear heater core with my first vanagon, an '87 GL.  I
removed the heater core and a nice guy named Mitch at VW Haven in
Pittsburgh created a metal bypass for me.  For cleaning, I removed all the
carpets and mats and soaked in some degrease solvent.  That and some elboe
grease should do the trick.  Good luck.
