I have polished aluminum Boyd Coddingtons and they seem to love taking on brake dust and getting corroded-looking. I've tried almost every type of brake dust remover, wheel cleaner and scrubbed them to death, but to no avail. Any suggestions? I haven't resorted to anything like a dremel polisher or scrubbing with steel wool for fear of really wrecking them, but I'm out of ideas...:shrug:
