A contact is a contact, it doesn't really matter where it is, you KNOW it's
going to accumulate dirt, dust, debris and potatoe chips over time.
You think you're stupid, I've got 2 used scopes from EBay and they both
work. D'uh...
I'd be hesitant about spraying stuff in the innards as well. But I'm sure
that contact cleaner would do it some good, especially when the units might
have done some duty in dirty shops. then a blast of fresh air in there
would help get the grit out.
But best thing would be to replace the pots altogether. I've never opened
mine(s), but I would bet they are modular and you can remove a board for
service. They wouldn't provide those fancy-shmancy service schematics if
technicians couldn't get to the components.

Hi Guys,
...
The only thing I can think of is something I remember my father
doing years ago on a television set with a mechanical tuner. When
it wouldn't tune a channel, he would spray contact cleaner on the
tuner and life was good again. I am wondering if it is possible
that some of the quirks of this thing could be caused by dirty
contacts and such?
....
