[TenTec] OT - Desk Microphone Switch Issue

[Rick - DJ0IP / NJ0IP]

On this side of the pond we have different brand names but most likely the
same stuff.

Our "Kontakt" cleaner is probably similar to De-Oxit.
Ours should never be used alone.
We spray it onto a switch contact, activate the switch several times, then
let it sit for 10 minutes.
THEN using a second spray called "WL", which is just a cleanser, we clean
the Kontakt spray off of the contact.

After it's clean, and if it's a relay, then we use the burnishing tool -
then rinse with WL again.

BTW James... on your clock - you're a lucky many.
WD-40 = Wait Delay 40 years.
You only had to wait 30.
Maybe it was sprayed with WD-30!  ;-)

OK... Yeah, I only use WD-40 to loosen stuck stuff.  I use oils and other
lubricants to lube stuff.  WD-40 will lacquer in time and gunk up the
process.

I have some RadioShack contact cleaner (which I believe is re-branded
De-Oxit) and my worry is that it will damage the little brown "wafers" 
which separate the switch elements or make them conductive in any way.

This is my worry:

I am a rookie, but I know phenolic surfaces may absorb fluids depending on
how porous they are. So I would not want to apply any polar
(conductive) stuff on them,  such as a solvent that has alcohol in it. 
The alcohol could be absorbed into the phenolic wafer, and not completely
evaporate, making it conductive, causing the switch to short.

I figure... The DeoxIT D5 (flushing, slow drying version) or DN5 (quick
drying, non-drip version) should be OK on the CONTACT AREAS of the switch,
but maybe not if I get too much on the di-electric insulator wafers in the
switch mechanism.

SO... maybe I try a little contact cleaner, USING A COTTON SWAB to keep it
on the metal contact area, and keep it off the wafer material as best I can.

Does this compute???
