Pot Cleaning Cap

About This Item

The easiest way to clean noisy control pots, without extracting them from a guitar, amp, or stomp-box!

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.

We recommend DeoxIT Pot & Switch Cleaner.

TIP: Aerosol contact cleaners can spray cold, and can potentially crack a guitar's finish. Always protect the finish with a cloth when cleaning pots and switches.

Bought a 1960 ES. Those old pots were scratchy. This cap and a can of CR was all she needed.

Doesn't fit them all

By

Verified Buyer


This worked perfectly for my Gibson ES-335, the pot is 100% normal, static free, silent. Amazingly simple. I removed the hex nut fastener on the pot.

This was a disaster on an Ibanez Universe. Threads are not proper fit, Deoxit wicked under the clear pickguard. Emergency string removal, pick guard removal, and pot removal for cleanup. No matter where I sprayed, this pot is still scratchy.

Cover everything, Deoxit will get everywhere. This is a messy operation and the Mrs was no less impressed. There was no problem with the red deoxit tube fitting the feed hole, perfect fit. But it blows out the top, and if the threads are a misfit, it will get all over the guitar.

Good times...

Hole is too small to accept tube from DeOxit

The diameter of the tube on the DeOxit is too large to fit in the Pot Cleaning Cap. I found an adapter that solves the problem.

Doesn't work anymore

As I wrote earlier the straw on the Deoxit has been changed so that it no longer fits in the cleaning cap. After I mentioned this to Stewmac they refunded my money for both items(thanks Stewmac). They said the change was made without notifying them and they're working on a solution. I hope this can be sorted out since I like the idea.

Worked Well on ES-335

By

Verified Buyer


Used with DeoxIT on an ES-335. Some have mentioned trouble getting the straw to fit through the side hole in the cap. I found the hole large enough, but once inside the straw bumps up against the shaft of the pot. Still, enough of the straw gets through to dispense the DeoxIT inside the cap.

StewMac pot cleaning cap - functional but messy

By

Verified Buyer


I used the StewMac pot cleaning cap to clean noisy scratchy pots on several amps. The cap works as described and is easier than taking apart the amp to get to the pots. The pots are nice and quiet now. However, the cleaning cap is very messy. Even with the shortest burst from the Deoxit can, fluid sprays back from the hole in the cap and from underneath the cap (where it makes contact with the pot.) I wrapped a rag around the pot stem and cleaning cap which helped keep the mess minimized and the spray out of my face - recommend you wear safety glasses when using the cleaning cap.

Hmmm.

Well this is a great idea in theory. However as one reviewer wrote the tube for the DeToxit is too large to fit the cleaning cap. I tried this process on an old Hagstrom Swede that I bought a couple of years ago and with mixed success. the De Toxit is great stuff but so is any contact cleaner. The cap is specific to one thread and therefore useless on any others. Make sure of your thread size before ordering or you may have a useless piece of metal. Perhaps Stewmac could offer a kit of common post sizes with appropriate threads and then this would be the bomb! Also a matching tube on the DeToxit is an oversight that needs correcting.

Not working for me.

I see rave reviews here so am I doing something wrong? The cap fit on my pots but the straw on the Deoxit is twice as big as the hole in the cap. The picture shows the straw going into the cap which is not possible. Spray goes all over with much wasted.

Pot Cleaning Cap

This item did exactly what it should do for unsealed pots. I have a vintage Fender Dual Showman of 60's vintage. I thought I was going to have to replace the pots but this gizmo did the job. Well done designer of said gizmo. Make sure to use the DeoxitD5 with the pot cleaning cap. it is the best! Very smart and resourceful design.

Works great ( for pots with 3/8 bushings)

By

Verified Buyer


Works great for any pots with 3/8 thread bushings so if you try this on any guitar with the cheaper pots it won't work. Wish they would make one of these for the metric pots.
