Thank you so much, I'll try it over the weekend when the De-Oxit arrives.
You need to pull the adjustment knobs off and then unscrew the thin nut that screws onto the threaded shaft so that the entire potentiometer will pull back freely. Spray De-Oxit in every opening you can find on the potentiometer body and turn the shaft back and forth vigorously many times to disperse the De-Oxit on the contact surfaces.
If you still need to remove a "faceplate" then prying it out very gently at multiple points around the perimeter would be the way to proceed but it could do permanent damage to the edges where you are prying.
