i know this isnt a recording website but i thought id post just incase anyone knew the answer to this question. Can one clean faders. I have really nice faders on my console, DDA, i beleive their alps faders. 90% of them work like they should, smoother than a babys bottom, but a few are a little gritty. Can i take them apart and clean them up to make them smoother, and if so how would i go about doing that?
