Looking for a brake dust remover

Ive got a set of wheels I need to paint and the backs are pretty heavily loaded with brake dust. I`ve used some brake parts cleaner and a maroon scuff pad to remove most of it but there is still some there. I`m actually planning on blasting the wheels so I may be wasting my time anyway. Just wanted to get off as much as possible before blasting.

Iron-X paste works well.

I think I’d just blast them? Probably would save money and time . Griot’s iron and fallout remover is an excellent wheel cleaner.
