Slider / mini fader death. Previous tech wash out.

[rmoondoggy]

I have had good results with this:

CAIG Laboratories DeoxIT Fader F5 Fader Lubricant 5% Solution - 5-oz. Spray.​

It has extended fader life for me. But, in the end Ethan is right; new faders would be the fix.

The can says it is made for "conductive plastic faders", but it works very well on the carbon element faders and pots. It definitely does improve the feel and noise.
