A non-abrasive method of rust removal is to use a length of plastic pipe. Cap one end, drop the driveshaft in. Fill with de-rusting solution, cap. A few days later, as clean as can be.
I believe that was how the '72 Trans-Am resto drive shaft got done on the SYC site. Wire wheeling won't get all the pitting and may destroy what is left of the factory markings.
