With the LP spinning, using very light pressure, hold the brush on a line from the spindle to the outside of the LP for a couple of rotations. Then, give it a light "flick" to remove the particles that don't cling to the brush. Do it again if you see any dust remaining.
I like to do the above both before and after playing (gets rid of anything before the LP goes back in the jacket.
