As you all probably know the brake dust on BMW's is both plentiful and damaging on the wheels of these cars.
I've somewhat recently come across bunches of little black specks on the surface of my wheels. If you rub your finger across them they will feel elevated and rough.
Long story short, I've tried pretty much everything to remove them: Sonax Full Effect Wheel Cleaner, P21S, Lighter Fluid, Clay (mild-type), Bug & Tar Remover, scrubbing it with a toothbrush, etc. Nothing budges the specks.
I've heard a couple of people have used this product called Prosoco 600 with great results for this exact problem. The only issue with this is that this is a masonry and brick cleaner and contains hydrochloric acid, which I'm sure is not the greatest thing for wheels. I also have on hand an alkaline masonry and brick cleaner made by Zep, but that would probably ruin the wheels as well.
What can I do?
