First get a small vacuum they use on computers , the if that works stabilant 22
put on the pot ,I have had a similar problem with dust and this is a super conductor protectant and fixed many a oxidized component well worth trying and the stabilant 22 Is great for all low powered items like rca,speaker terminals used by hundreds of high tech
companies for years and makes everything sound a bit better once cleaned including vacuum tube pins and protects if not moved for a minimum of 12 years
if this works I would put some electrical tape around the exposed area to seal
it if possible. If you have to replace it buy a better one like a Khozmo attenuator
they use a resistor ladder and only 2 resistors on the output and is sealed
about $400 with nice remote if you have to do a repair make it better with a few mods.
