I use this with a chemical guys brush and it's a great combo. It literally melts the brake dust away.

buy the low dust pads and swap them out. Thats what I'm running

 

I put menzerna power lock on the wheels. Going 2 months strong and my power washer will take off 95% of the brake dust no problem.

 

Yes, Sonax is good but with one bottle you get about 3 applications. But I coated my rims with CarPro CQuartz so it comes off easy, many times just water hose but some agitation with basic wheel cleaner and sponge will do the job
