Poorboys Spray and Rinse is hands down the easiest wheel cleaner to use on brake dust. That said it is heavy hitter (citric acid based, not hydrocloric or lye like store bought) and you should heed the directions. Wet wheels, cool wheels, and never on uncoated aluminum. It works on chrome well, and you will only need to use sporatically (monthly).
I also highly suggest coating the wheels in DP Wheel Glaze or Poorboys Wheel Sealant afterwards. Usually car soap and water will work for several weeks and then you can do both again as needed.
On a seperate note, seriously consider ceramic based brake pads on your next replacement. There is no percievable dust, and they work well in almost all circumstances.
