If you talk about break dust the Brake dust is produced as the brake pads in your car wear out as it rubs against the brake discs (or rotors, if you have drum brakes). Most brake pads contain metallic compounds, and so you can think of brake dust as tiny metallic beads that cling on to the surface of your wheels. Because the brake dust can be abrasive when rubbed against the surface of your wheels, you want to take extra caution while cleaning your wheels and you want to clean your wheels as often as possible.
First, you will need to wet your wheels with a spray of water. Remember to do this in the shade, as you want to keep the surface of the wheels wet through the entire process. Then, spray on the Wheel Cleaner on your wheels, remembering to get the inside of the wheels. Less is more, so don't over-do it. Move on to the next wheel and do the same. By this time (about a minute or two), you can go back to your first wheel and with the Boar's Hair brush (or other similar, non-scratching yet stiff brush) agitate the wet surface to lather up the cleaners and the brake dust should easy break loose. The trick is reaching the inside of the wheels, through the spokes. For this, I use the 3-finger mitt which allows me to reach through the spokes without getting my hands cut up on the disc brake covers and metal parts around the brakes. After all the brake dust is loose, a quick rinse with a stream of water will leave a nice, shiny wheel. It's really that simple!
