I clean the spoke in the same way...Takes about 10 minutes/wheel.
Don't worry, I tested the brass brush on a hidden surface of the rim first and it was fine. That hard anodizing is tough stuff. Unfortunately, the brass brush wasnt as effective as I thought it would be on the nipples. It did do a nice job cleaning up the ferrules in the rims. I'll try luker's method next but maybe with a cotton shoelace if it will hold up through an entire wheel.
