I just use a 3M Scotch-Brite disk on my drill, like the bottom ones in this kit - http://www.amazon.com/3M-03050-Scotch-Brite-Automotive-Finishing/dp/B000CPZYCM. I think the ones I have are 3" diameter instead of 2", but whatever. With the rotor off the car I lay it on the ground and spend maybe 30-45sec running the Scotch-Brite pad around each face of the rotor on my drill, then spray it down with brake cleaner and wipe it off. Nothing special.
I do this for both street pads and track pads, works like a charm. The last time I turned a set of rotors was ~15 years ago, prior to my first track event. Since then I've been doing my own pad swaps, and just scuff the rotors myself.
