First off try wheel cleaner and a scrubbing brush.
Brake dust etc sticks pretty well and just a pressure wash usually won't shift it all.
I've found bowdens wheel cleaner (at supercheap) to be the best off the shelf cleaner I've used.
The meguiars "hot wheels" one was crap.
If that doesn't get them as nice as you want then consider a repaint. Can be done as cheaply as $60 if you do it yourself, or a few hundred for a shop to do.
