Tried and true method:

Remove all the tubes and anything else that can be taken off or out. Fill a
squirt bottle, preferably a nice big one with adjustable nozzle, with
denatured alcohol (about $12/gallon) and give the thing a shower. Keep
spraying in every nook and cranny until the runoff is clear. Warning - you
will go through a lot of alcohol so buy two gallons. The adjustable nozzle
helps a lot; some areas you will want a wide spray and others you will want
a thin strong stream. After the runoff is clear, keep spraying some more.
Then some more. Keep bathing the thing until you run out of alcohol or your
hand starts to get cramps. Another warning - do this outside - the fumes
are strong although not particularly toxic.

Then let it dry for a few days. It will come out perfectly fine, with
absolutely no harmful affects. I would NOT use water, although I hear
people do it.

This is also the best way to remove cigarette smoke smell and tar from
electronics. The alcohol dissolves the brown gunk like nothing else; it's
amazing.

I have just started to restore a HQ-145. The external cabinet is 9.7+ and
is fine [for now]

The chassis needs a good mechanical clean up. What is a good 'stuff' to
remove hard cased surface dust and some minor staining/discoloration?

If the 'stuff' exists, is it commonly available?
