As chnace would have it, i'm painting my calipers before they're installed. This is going to take approximately 1 week so be patient.
Tools
Dremmel with Wire Brush attachment
Polishing Bit
So after some time removing oil residue and scrubbing with wire brush i hooked i the dremmel and results are good thus far. The brake dust is stubborn and will not come off even with really harsh degreaser. ~becareful not to use harsh liquids as they may damage piston rubber boots.~
