I'm assuming spraying down the shaft with a cleaner/ lub and work it
is the best way to do this?
Some pots have openings in the body also and is this a better option?
Cheers!

Better to shoot cleaner in the opening when possible. Sealed pots
shouldn't be sprayed.

Sealed pots are only sealed to prevent contamination from external sources.
They still go bad, and still benefit from cleaning, if one can gain access
to do so. This applies to deposited carbon potentiometers. Many modern
volume controls are actually rotary encoders, and cleaning them is a
crap-shoot. Those must be taken apart and tarnish cleaned from the internal
workings, and since the controls are cheap, better just to replace them when
possible.
