Michelins Wheel and Tire Cleaner works for me. Of course, I don't let that brake dust accumulate and our driving doesn't require frequent brake application. Seventy one thousand miles on OEM brake pads which are fifty percent gone. That cleaner in the purple jug at Walmart works good on brake dust. Allowed to accumulate, brake dust sets up a chemical reaction with alloys that has a life all its own.
