After removing the dust in a way that won't cause any electrostatic
discharge to zap anything, and removing all of the boards and other
electrical components, take the cabinets, etc. outside on a warm sunny
day and give them a good blast from the garden hose. Then, let them
dry in the sun, which shouldn't take too long. Simple Green seems to
work wonders on dirty plastic cabinets.

It seems to me that soaking extremely dirty circuit boards with a
garden hose, as long as they have no stickers, or EPROM covers, on
them, whcih could come loose, and then letting them dry thoroughly on
a warm afternoon, should cause no problems. Any thoughts on this?

Note: you might want to be careful with the dust. I don't mean to
sound like an alarmist, but in a small percentage of collected
systems, dangers may lurk. Some dust and residue may cause no
problems other than to irritate allergies; however, carcinogens and
other biohazards may lurk in some dust.
