From looking at a picture, it looks like the easiest way to clean them is
to remove the top cover and get in there with some dust off, or filtered
compressed air if you have it. This probably requires removal of the
dimmer pack from the rack, so you'll need to shut off power to it (which
you
would do anyways) and undo all of the connections if it has a terminal
strip instead of plugs.
Have run into fun times with dusty dimmers before. A Colortran rack I
used made all of the lights flicker because a temp sensor was being
effected in
the controller pack.
