I found the same problem with the Auto Glym spary tyre dressing, I still use iut, however have changed the way I finish the cleaning process, after washing the car when cleaning the wheels and tyres I wash off the brake dust, then dress the tyres before wax finishing the alloys, I find that the wax on the alloys which I apply with a cloth (standard car wax) adds a protective coating which means that most of the brake dust comes off straight away and leaves the wheels looking great. I may stiull move the the green stuff pads and disks however after the suggestions earlier
