The thing about the Dremel tool is that it can get away from you pretty easy if you don't have experience and you can find the buff (or, far worse, the knurled nut on the collet) grinding against your mouthpiece facing before you realize it.
The bench grinder with buffing wheel, on the other hand, excels at ripping the workpiece out of the hands of the inexperienced user and flinging it across the shop, or against the back wall.
If I were going to do something other than ignore this discoloration (because that would always be MY default position - don't do something, just stand there!) I'd take something like Simichrome on a rag and lightly hand buff it and see what happens. No more than that. Applying power tools to a job meant for hand tools, when you're not in a production environment, and when the operator has no experience, is not a real good risk, in my mind.
Especially when we're talking about a minor aesthetic degradation that has no functional effect, and probably half the folks over 50 playing hard rubber MPs have several that've turned green just by age. So you won't be the only one with a green MP out there.
