Specialized Electronic Contact Cleaner
The vast majority of scratchy potentiometers are caused by surface oxidation or dust buildup on the internal resistive track. This chemical solution deoxidizes the metal wiper and flushes out contaminants without damaging the plastic housing, restoring a clean electrical path during rotation.

Replacement Gain Potentiometer
If the resistive carbon track has been physically scored or worn through due to high cycle counts, cleaning will not resolve the issue. Replacing the individual rotary potentiometer restores the mechanical and electrical integrity of the gain stage at the component level.
