I took the advice of another thread group and used the Castrol Super Clean. It was about $6 for a gallon and you really need to cut it with water (about 50/50%). This stuff works like a charm and the interior of my '75 Excella looks great. It wasn't in bad shape before, but now it looks even better.
My next step is to put a couple of coats of the Future floor acrylic. Both products were found at Wal-Mart. Good luck!
