[R-390] Cleaning modules

[Barry Hauser]

Simple Green, like Formula 409, Fantastic, etc. is an ionizing cleaner -- it
can leave behind salt compounds.

There have been reports of the stuff saturating phenolic and ceramic
insulators -- as in rotary switches and tube sockets -- and turning them
conductive enough to arc.  At least, that's what I read a few years ago.
May well be that those who apply Simple Green liberally - then maybe flush
with distilled water - are lucky most of the time.  And maybe it depends on
the specific insulators involved.  Most ceramic tube sockets and switch
parts are glazed -- but not all surfaces.  The flat sides of phenolic wafers
are glossy -- but not the die cut edges.

Probably depends....

Anybody ever try one of those steam cleaners?
