> I use a shop vacuum in reverse (warning)

That warning is correct!! My simple advice, after 20+ yrs of exp. in
maintaining and repairing, about cleaning anything with an IC or the like:
ONLY USE:
1) To blow out dust:
  a) A hand-bellows with or without a brush of elect.-neutral hairs,  or
  b) A special lab-compressor, producing abs. dry and elect.-neutral air.
2) To vacuumclean:
  a) Such a one-hand Mini Vacuum Cleaner. Less than € 10 or US$ 12.50 in the
      usual stores,  or
  b) A lab-vc, driven by 1) b.
Well 1) a and 2) a are the only safe and low-cost solutions for the normal
users and the b's will be for the more prof. users.

Sorry, but this will be a very wrong suggestion!! FOR: 98% of, or even
probably ALL, compressed air cans will produce condensations which can be
fatal!! ONLY use compressed air cans for empty cases etc. but NEVER with any
elect.'s in the surroundings!!
Just 2 days ago, one of my clients blew to hell his Nikon LS-2000
slide-scanner by using a compressed air can!! A complete short-circuit on
the board! Cost of repair will be higher as the scanner is worth.
