I spun mine in my lathe, using emery cloth to clean them.
This is not much help if you haven't got a lathe!

Spin 'em in an electric drill , use emery or wet n dry , but not on the seat area !
Or you can chip away with a knife and finish them off on a wire wheel....

Not with your finger I hope David, but with it nailed to a piece of wood?

Put em in a drill and spin em with some emery cloth. If they are a bit sticky spray em with WD to soften it up.
I usually clamp the drill in a vice to make it easier.

Why would I want to nail my finger to a piece of wood! 
No, I used a thin strip of emery cloth held lightly between my fingertips - fully prepared for any snagging or tangling whipping the cloth out of my
fingers.

If you have one use an old valve as a chipping hammer , chip off the worst of the carbon, then if you have access to one use a bench grinder with a
wire wheel to clean off the rest. If you haven't got a bench grinder try paint stripper or gasket stripper , excellent at removing carbon from
heads and valves

nowt wrong with putting them in a drill, does the job fine. People have been known to make very effective wasted stem valves like this! (needs
considerable care though!)
