Re: Cleaning Switch contacts and machanisms on HP239a Oscillator
I too have used Deoxit successfully. I've used it since 1986,
when I wrote an article about contact cleaners for EDN. Back then,
it was called Cramolin and came in blue and red. Still have some
of that. These days, I use Deoxit Gold. Just type "Deoxit" into
Amazon to see what's available.

I collect HP test equipment too… I use DeoxIt to clean such rotary switches. Good luck in your restoration!
