The problem with brake dust and alloy wheels - it's not just a dust that
settles on the wheel that can be removes by cleaning. It is a corrosive
material that actually etches the wheel. Think about that the next time
you're working around the brakes - it;s best not to breathe that stuff. So,
typically, cleaners that work on the surface will have limited results.
Something must be used that will work down into the corrosion.
If you have wheels which are not heavily coated with brake dust, the best
way to keep them that way is to hose them off once or twice a week followed
by an ocassional coat of wax.
But to prepare the wheels for painting many people have the wheels bead
blasted - then they are primed, color coated (Astral Silver IIRC) and clear
coated.
Bead blasting is widely suggested as being the best way to prep the wheels.

Andrew,
Unless you plan on repainting, do not use Brillo on your bundt alloy
wheel(s)? I tend to use Simple Green when I wash mine and this does
quite a
good job, but yours may be worse. Worst case scenario, without adversely
affecting the paint/clear coat, I'd try Easy-Off oven cleaner. Good
luck.
Anyone know what pros do when they are planning to paint, chrome, or
powdercoat wheels? There must be some definitive surfactant or
solvent out there that lets you get every last bit of brake dust
without endless scrubbing in the nooks and crannies (those of you with
BBS-type spiderweb wheels know what I'm talking about) but doesn't
harm the aluminum.
