Ah crap, I didn't notice the crossposting until now, I won't keep this
thread going beyond this, I thought I was only replying to
sci.electronics.repair which is something that rarely requires air.

Not to sound trollish, but one of my pet peeves is the lack of compressed
air capability in electronics (and formerly computer) repair shops;
cleanliness is next to godliness in equipment maintenance and for shops
not to at least use compressed air to clean dirty customer gear is to me
unconscionable (when needed I would expect hot high-pressure non-ionic
detergent cleaning as well).

Static electricity and electronics don't mix, not to mention breaking
things. Using a compressor to blow out computers may do more harm
than good.

Our regional Tektronix repair depot _routinely_ hot-washed and baked
instruments that were brought in for repair.

Quite a different thing, though I wouldn't do this either, unless the
equipment was made for it.
Low pressure air is standard procedure for cleaning out computers that
are in normal dusty condition, and after fires and disasters,


130PSI @ 10CFM is not "low pressure". I see all sorts of "standard
procedures" go on by monkeys with screwdrivers.

computers were routinely cleaned with a type of "dishwasher" with a
speacial cleaner, then vacuum baked dry.


Routinely? Mine never have been. I know the Tek stuff mentioned
earlier is designed not to trap solvents and the gunk they leave
behind.

Today's computers ( and almost all consumer electronis) are cheap
enough that replacement is almost as low cost as salvaging.


I'll agree there. If it's going to get that dirty in a couple of
years, perhaps one ought to clean house a little more often. OTOH,
I learned not to put towers directly on the floor. They make good
cat-hair vacuums.

Indeed. I used to put my stuff on the floor in order to gain a
little extra desk space, but after seeing the air intakes turn black
and get clogged with whatever, they're now on my desktop and
breathing at about the same altitude as I am.

No matter how big my desk is (or how many) there is never enough
space on it[*]. I generally put the towers on a shelf beside the
desk. Even a foot off the ground is enough to keep them from
constantly vacuuming the floor.
[*] It seems seems to be a fundamental law of the universe that all
horizontal surfaces will be full of stuff.
