Be careful using Simple Green and/or Swiffer Duster. Your best bet aside from using the low-dust pads (assuming you're not participating in track days), is to properly clean and seal the wheels. I recommend using a good wheel cleaner such a Bilt-Hamber Auto Wheel or a Sonex, followed by a Bilt-Hamber Korrosol or Iron-X to remove any remaining metallic particles that are still in the wheel, then clay using any one of the soft/medium clay bars with the corresponding lubricant. Once complete I would dry the wheel and check for any remaining debris. Apply a good wax and/or sealant such as Collinite Insulator Wax and/or Menzerna Power Lock which will make the wheel finish look better than new, but also protect better than most other options. After a long drive, you should be able to hose off most brake dust followed by a soapy wash to get the remainder off. Good luck and let us know what method you try.
