[Amps] How to safely clean an amplifier?

[Harold Mandel]

Jack,

You know in your heart the only true method
is a total refurbishment: Yank every single
component out and reduce the unit to a bare
metal chassis and have it re-plated with
Iridium Class-III (conductive yellow).

Is this your only amp? Did you buy it just to
get a signal on the air or for a tinkering project?

Cheap and dirty involves setting it on a milk
crate in your driveway, removing however much
as you can, and using cans of tuner cleaner,
an air compressor and a stiff parts brush,
blow the crud out, wipe the metal and paint
down with Windex, let her dry up and 
slam it back together.

I would like suggestions for a suitable cleaner to
safely remove any deposits of dirt/crud that require
more aggressive cleaning.
