I take it this is dirt and dust collecting between the plates.

Yes, most likely dirt, although it may also be worn out. TV tuner
cleaning spray can be tried. It comes in a spray can and usually has a
plastic "straw" that attaches to the spray head so you can direct it
into any small opening in the potentiometer (the volume control). Spray
a bit in there and rotate the volume knob several times over the full
range of the control.
