The only thing that has worked on a 40k mi audi
Brake dust was bonded to the paint on the inside of the wheel, like pitting of IRON on these wheels.
No cleaner (even WB at full strength) could 'easily' get it off. Basically the only way I was able to do it, was get some adams grey clay, some WB 1/2 and a stiff bristle brush and the hose.
Apply WB, scrub for 2-3 minutes a small section.
Hose off with water.
Clay the shit out of it with a used piece of clay.
Apply WB again, scrub with brush, hose off.
Repeat until section is clean (probably about 5-10 minutes) move onto 'next section'.
They key is to not scrub the clay with the WB on the wheel. It will begin to eat the clay and breakdown the abrasiveness. (bad) This process was used for the inner side of the rims, not the outside.
Just my process for wheels spawned and baked in hell,
