Standard glass bead blast media is fine. . . but . . .make sure you change
it out for cleanliness, don't build parts too hot, and keep the air pressure
just right. You want the pressure high enough to remove all the powder, but
not so high that you can "burn" the part. If you do discolor, you can
wet-sand the part and get most of it off, then re-blast it.
