Alternator + Bench Grinder = ?????

[vex]

So I'm going to tempt fate here and post a silly question I already think I know the answer to. But here it goes anyways:

I have an FD Alt I just got in the mail. I've already broken it down into the different components and wire brushed on a bench grinder the case. They look really, really good.

Now i'm sitting here and looking at the stator. I want to do the same thing to the ring on it, but I'm thinking it's not the wisest course of action as I may damage the wires.

Is the club in agreement that it's not the wisest course of action to put a wire bush from a bench grinder to the Stator? If so how can I clean the ring?

After that I want to clean up the rotor assembly but I'm not sure what I could get away with on that. Don't think a wire brush would be the best choice. Suggestions?
