Board Cleaning Opinions Wanted

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.
