I would add caution to what the video offers for '80s era controls, most especially regarding more modern faders and potentiometers, made with often esoteric materials.
I have seen standard spray contact cleaner actually dissolve modern guts of faders, costing a lot to replace. Then looking up what to buy for replacement parts, you re-discover a warning to NOT use canned contact cleaners.

Just make sure what you spray into your controls is compatible with your equipment.
Often, a Q-tip with a dab of isopropyl alcohol will make quick work of oxydation build ups. Then, of course you must sometimes replace the lubricant that came from the factory when the item was new.
That can be tricky as well.
RTFM!
Not everything works the same as the '80s synth the guy was using as a test case.
Use caution.

Often, as JBz said, just moving them back and forth will often clean them sufficiently, except for the extremes of the adjustments, where all the stuff you just wiped off of the centers of the controls ends up.
