Board Cleaning Opinions Wanted - test-drb@ccmp.vtda.org

12 May 1999

When I had cleaned out my TRS-80 (was sitting on floor in basement when
septic tank backed up), I used a 40lb paint sprayer (air), with a cleaning
nozzle on it.  I put the suction tube into a bottle of Windex, and it worked
great.  I rinsed them by swishing them in a tub of warm water.

To dry the board, a dish rack and old hairdryer (hood type)with the heat
off, work wonders.

Good question!  The only circuit cards that I would have any hesitation
about would be those with pots/trimpots and perhaps variable capacitors
installed.  The possible problem there being getting them really dry.

   had a swim in
salt water (hint salt eats boards!).

  I'll leave the corestacks alone (well,
I'll use a soft brush to
 remove the dust from the *outside* of the 'sandwich'). 
 The core stacks themselves if there were even a hint of something nasty
 on them they'd get washed carefully, it's the fine wire I worry about.
 Generally the sense and driver boards are ok to machine wash.
