    Roger: Some pots have grease in them that dries. GC electronics make a
    cleaner called JifAction. It is cheap so you can flood the pots and not run
    up too big of a cleaner bill. Spray them. Let them sit a while and clean
    them again. Keep flooding them out. Might want to soak the mess up with
    rags while the unit is standing on its' side.

    If that doesn't work, as a last resort, use Brake rotor Cleaner from an auto
    parts store. This stuff eats plastic so be frugal. Blow the pots out with
    compressed air to dry the rotor cleaner out. I don't know if it eats the
    carbon or not. I have used it many times, it is very powerful. Vent the
    room good. It is degreaser for brake rotors.

    Afterward clean and lube with conventional control cleaner for electronics.
    JifAction works very well. Good Luck MH (top post)

    Only one choice: caig labs. D5 or Pro gold.
    Not cheap, but worth every penny,

    By an oversight and a serious lack of attention (happens to
    us all!), I acquired a used stereo equalizer some time ago.
    Predictably, darn it, the slider pots are either dirty or
    shot - the measured gain at the various centre frequencies
    jumps as various sliders are moved, and an ohmmeter also
    jumps on passive measurements.

    Slider replacement is out (parts too expensive.) So it's
    try to clean or throw out (perhaps cannibalize.) Does
    anyone have a recommendation for a potentiometer cleaner
    that won't actually dissolve whatever carbon is left on the
    tracks? I've tried "Power up" switch cleaner to little
    effect.

    Cheers,

    Roger
