S100 motorcycle cleaner is some of the best out there. It's not cheap though.
$17 on Amazon for a 33.8 oz bottle, doesn't seem too bad.

IronX or Sonax will cut through brake dust well -- I've used both, and I tend to favor IronX. Apart from that, I use Red Max by Majestic Solutions a lot as well. I definitely wouldn't recommend using a Magic Eraser on any surface that wouldn't be reconditioned after, as a Magic Eraser sponge will act as an abrasive. Sure, on an aluminum wheel you can hit it with some metal polish later, but on a painted wheel?
