Fader carbon track restoration

[It hertz]

I used an electrical cleaning spray on some faders and it has broken one of them. Taking a look inside the fader it seems that the solvent disintegrated the most worn parts of the track at the top and bottom, so the fader just measures infinite resistance between pins, but the rest of the carbon track still works.

I couldn't find a replacement available on Digikey or Mouser annoyingly, even though it's not exactly a vintage part. The unit in question is an Alesis Multimix 12.

Is it possible to restore the carbon trace somehow?

Conductive Pens

Conductive pens dispense conductive paint pigmented with either carbon, nickel, or silver. Each pigment provides a different resistivity.

if its just at the ends that may be a good case for one of those pens? just to restore continuity

Interesting, possibly worth a shot but I wonder about the effectiveness of this under a wiper.

What do these sliders do? Tone controls, balance, volume? If they're balance or tone controls, how often do you really side them all the way up or down?
If the dissolved tracks are just very short sections at the ends it may not really be an issue using the pens. Volume control however would be a different story especially at the bottom of the track.

Did you already try Instrument Parts ?

Faders on a mixer are not used for tone or balance.

Operating faders at both extremes is routine.

Ya, I'm not sure a pen is the best thing to use then. I would think it would weae off pretty fast from the wiper moving across it.
Have you tried to contact the company that made it? They may at leased have info on what they used when it was produced.

Pictures of the faders themselves might elicit more useful suggestions
