that final sanding dust in the grain where it stays.

Two good suggestions (bristle brush and brass brush) have already
been made. Two more are tack cloth (yeah, it's old
fashioned, but it WORKS) and plastic erasers (I really like
Staedtler-Mars Plastic erasers). Both work
by adhesion to the dust, and neither leaves any residue.

If your ventilation is good, you can try compressed air, too.
A little sunlight (or a UV lamp) would be recommendable,
because the dust can take on electrostatic charge and
get REALLY stubborn, The brass brush should discharge it
without the UV assist, of course.
