I have just started to restore a HQ-145. The external cabinet is 9.7+ and is

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?

I use some stuff called "Hood Cleaner" made by RubaChem Inc. Computer
maintenance division, PO Box 9841, Englewood, NJ 07631,
1-800-548-3285.
This is a foaming type cleaner. You spray it on and let it sit for a
while. It will loosen up the cooked on dirt etc. Seems to be real safe
on plastics etc. I would not use it on silk screen labels, especially
on dials that type. Avoid spraying on components that can absorm
moisture. Spray it on a cloth and wipe around sensitive components or
areas.
It really works wonders on cigarette smoked up plastic. Hope this
helps.
