The soap seems a good idea. I usually remove the grossest imperfections
with a small disk sander in a Dremel tool, and finish with fine steel
wool and then a metal polisher. But by letting the solder touch only
the interior of the ball, and polishing the ball surfaces during the
spinning procedure, there is very little to correct.
