Pot Cleaner Cap - Set of 3 caps for cleaning guitars and amp controls

Description

Pot Cleaning Cap - Set of 3 sizes for Guitars and Amps
This set of pot cleaning caps includes US 3/8", metric 8mm and metric 7mm caps.   If you just need one, single cleaning caps are available in my other listings.
They are available in stainless steel, brass or aluminum.
The 3/8" one is threaded to fit US pots like CTS that have a 3/8" by 32 TPI thread.   The nuts on these pots use a 1/2" wrench.  The 8mm by 0.75 size fits large (24mm) imported pots and some Bourns pots. 8mm pots use an 11mm wrench.  The 7mm fits Alpha and other metric pots that use a 7mm by 0.75 thread.   The nuts on this style pot use a 10mm wrench.
The adapters have a small hole for the tube from your favorite pot cleaning product (I like Caig DeoxIT).
Here's the process:
Pull the knob
Slip an o-ring on the shaft if there's room
Thread on the cleaning cap
Put the product tube in the little hole
Wrap a rag around the bottom (just in case)
Cover the open end with your finger
Spray
The cleaning solution is directed to the shaft of the pot where it can seep in.   You can turn split shaft pots with a screwdriver through the open end to work in the cleaner.
