Well, I took it another step, you can clean up wheels, and almost make them look new without having to respoke them (unless you really want too, but for the ones who can't afford it, etc.,..,.,). Takes a little time, but well worth it. I don't have a fancy Dremil tool, so this was done all by hand.
I used 250c grit sandpaper on on the spokes. It was a little hard to get the spokes near the hub, being all tight, and I have big fingers. Takes off rust, grease, or whatever else stained your spokes. Then, and jar of mothers, and a couple of rags, polished each spoke, buy hand.They look NEW.
Next was the sides of the rims.( this is for non chrome rims).Good ol silver 7X's. Bad brake wear (ive seen worse) This was a 4 step process. First, I used a old set of cheap Moongoose forks, and placed them into a bench vice, with the fork dropouts pointing up to the ceiling, and placed the rim into the dropouts. I used 100 grit sandpaper to start. Ruffs it real good.Then went to 250c git sandpaper to start the cleaning process.Took some time to remove the brake marks. Then took 400 grit sand paper, and spun the wheel, while holding the 400 grit against the side, making the sanding lines straight, and even, and smooth. Final step was to place a little mothers on the sides, and wa la :
BEFORE and AFTER
