Works for rotary switches and Gibson Varitone switches, too. The cap directs your cleaner right where it's needed, inside the pot housing on the contacts around the shaft. No mess!
"An absolute must for vintage F-hole instruments. Every guitar shop needs to have at least one."
—John Brown, Brown Guitar Factory
Simply remove the control knob, and screw the Pot Cleaning Cap on the shaft. An access hole guides your spray cleaner extension tube directly to the pot shaft. The cleaner flows down the shaft to where it's needed on the contacts inside the pot. A hole in the top of the cap lets you turn a split pot shaft with a screwdriver for thorough coverage.
Works with 3/8 x 32-thread, made in USA potentiometers: CTS, Allen-Bradley, Bourns, CentraLab, Clarostat, and others. It's not compatible with imported or metric-thread control pots (like Alpha).
Pot Cleaning Cap is made from precision machined stainless steel.
