Soap and water. Wheel cleaners generally clean better than soap and water for a reason. They are more aggressive on the stains...and the wheels. I've read too many horror stories about people who have used wheel cleaners and it damaging the wheels. Yes, I'm aware that many of those instances were because they weren't used properly, e.g. allowed to dry on the wheel prior to rinsing, etc. Many on this site have done other things to help with the dust including changing brake pads, ceramic coating etc. If you are going to use a wheel cleaner, avoid the junk you find at the auto stores or Walmart.
