Ed,
If it ain't broke, don't "fix" it. The most probable controls to wear
out are the AF gain and the RF gain, and if you use it a lot, the RIT
control. Wait until they get scratchy and then replace.
Rather than trying for a temporary fix with DeOxit or other compounds, I
suggest you simply replace the controls that are bad. What usually
happens is that the carbon trace that the wiper runs on becomes pitted
with use, and for that there is no good cure other than replacement.
Besides, the pots used are rather tightly sealed, and I don't think you
could get any spray inside where it would do any good. Unlike the old
unsealed pots of yesteryear.
Elecraft has replacement parts - I buy parts from them often, but then I
repair a lot of Elecraft gear - one or two each day is not unusual for me.

Greetings all....I just realized my K2 (# 3500+) is getting old, I can't
remember exactly when I bought the kit from Elecraft, but at least 12-13 years
ago.
So, as things begin to wear out, any suggestions on what to clean, as in
different front-panel POT controls that and suggestions what to use to clean
them? I have used Detoxit and it seems to work very well.......
Thanks all........73
