Pot Cleaner Cap - Set of 3/8" and 7mm caps for cleaning guitars and amp controls

Description

Guitar and Amp Pot Cleaning Cap 3/8" and 7mm - Stainless Steel, Brass or Aluminum
Pot Cleaning Caps
This set of pot cleaning caps includes both US 3/8" and metric 7mm adapters.   If you just need one kind or the other, 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 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).
NOTE - The adapters only fit the small red straws.  Caig has a newer yellow "Perfect Straw" that does not fit into these adapters.
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.
