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

- yes, I'm a lazy CW operator!). Is there any cure for this - other than

close to the button body as possible and remove them from the board one
at a time.
