Cleaning Knob Panels

Does anyone have recommendations for cleaning knob panels on a Sub 37 or Matriarch? Mine have gotten pretty dusty. I was thinking maybe a vacuum cleaner with a brush nozzle.

On a related note, my Sub 37 pitch and mod wheels had gotten a little gummy over the years and so I was able to carefully clean them with a paper towel and rubbing alcohol while it was off. I was particularly careful not to put too much on the paper towel as to not drop inside but alcohol evaporates quickly so it wasn’t much of a problem.

Get a can of compressed air and a Swiffer. Works great, no liquid.
