V4 PCB component repair/updating

Is it possible to use Deoxit for the rocker switches? I get a bit of scratchiness when using the Treble rocker in the highest/right position.

I would recommend using a cleaning agent that doesn't leave an oily residue like deoxit does. big bath is great stuff (just dont let it get on your black plastic knobs... it will discolor them)

alternately, you can take the switch apart and clean it manually (99% alcohol on a q-tip would work fine in that case)
