Soak the part in solvent (kerosene should be fine) then blow it off with compressed air. Make sure to blow out all the passage ways. When you are absolutely sure its clean do it again.

Agreed. I had the impression that the solvents didn't dissolve the blast media but helped dissolve any little traces of oil or whatever that was causing blast media to stick to the aluminum. The solvent soak just helps free up that debris and hopefully give you a clean surface when finished. Blow off with compressed air and repeat the soak/blow-off cycle a few times to make sure there's no media still on the part.

That's interesting. A fine file had crossed my mind as well but I thought that would be very prone to leaving scratches behind. I guess it probably takes some experience and a fine touch to perfect. I'll keep that in mind. Thanks for the good info.
