Dave Smith Instruments SYNTHESIZERS

Some knobs on my MED have started to misbehave, and I would like to clean them. There's a page on DSI website that describes cleaning knobs on a keyboard Evolver, but there's nothing about desktop Evolvers. Has anybody successfully cleaned the knobs an a MED? How did you do it, and what did you use? (DSI recommends Deoxit, but I wonder if a generic no-name-brand contact cleaner will do).

cheers,
Boris.
