Ever since I bought my Z4 and now that I have the 135i, I have used various products for cleaning the brake dust off my wheels with good results. A few weeks ago I ran out prior to my usual weekly wash. I use a foam blaster for washing the car and decided to use it on the wheels. The brake dust dissolved quite well and after using the wheel brush the wheels and tires were completely clean. The next time I washed the car, most of the brake dust washed off with just the pressure of the hose with clear water. The remaining dust was completely gone after using the brush. I'm through with buying special wheel products and just using the car washon the wheels.
