Ha, so we do have a common past.
Actually we were Tektronix.
We had the exclusive distributorship for Germany for over 30 years.
We were treated just like TEK employees. Same training, etc.
In fact I am still a member of the Tektronix ham radio club which consists
of all hams that ever worked for Tektronix.

This brings back memories, as I used to repair and calibrate Tektronix
oscilloscopes in the '70s too. Our procedure was to rinse them (the whole
scope) with deionized water. Wash them with a solution of water and a
product called "Kelite." Some sort of detergent from Allied Chemical, rinse
them with DI water again, and put them in a drying oven for about a week.
When we got them out of the oven we carefully applied
WD40 to every switch contact and connector using a small paintbrush. We
absolutely did not spray WD40 on anything. It was applied carefully only to
the contacts and the positioning ball/spring thing in rotary switches, also
the wipers on potentiometers. I suspect that DeOxit or Cramolin would have
been better than WD40, but WD40 is what we used. I'm pretty sure we were
following Tektronix recommended procedures.

I suggest that a small paintbrush may be a better option than a Q-Tip.
The cotton fibers of a Q-Tip could catch on something and be left behind on
the contact. I think with a tiny paint brush you have less chance of leaving
a bristle behind.
