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.

Not working for me.

By

Verified Buyer


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.

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.

Handy for those times you don't want to charge 180 bucks to spray pots.
Making friends is a good thing right .

Pot cleaning cap

By

Verified Buyer


I like the idea of this device. I had to remove the nuts from the pots to screw it on. The cleaner shot out of the opening of the top all over the guitar but it did clean the pots. I will have to remember to put a finger over the opening and wear goggles next time. You can also catch a spider and zap it with bug spray.

Useless

Doesn't work. Period. Hole is to big and lets all the lubricant spray back in your face. This is a sorry tool.

Response from StewMac


Thanks for your review. It sounds like this may have not been used on the correct 3/8 x 32-thread pot, causing the issue you have described. You are welcome to return this for a refund or exchange at any time.

Cleaned my pots

The key word here is, directs the cleaner onto the pot shaft for a better penetration. Use common sense and know that their is always a spill over so as they suggest have the finish covered. This is a major time saver, and gives me no excuse not to have all my pots in perfect quiet working order. Thanks for another great product.

Is it Worth $20? You bet it is!!!

I have a vintage Jim Kelley 80's Tube guitar amp that I have owned since 2000. It has always had noise. I just accepted it as the price for the awesome sound when the pots were set and hoped it did not crackle during a performance. After I used the Pot Cleaning Cap all of the pots now have no noise at all, ever and my baby has never been so quiet! Great Job!!

I ordered the Pot Cleaning Cap and the CAIG DeoxIT Pot & Switch Cleaner together, and the results are a beautiful thing.

Both performed as advertised. DeoxIT's improved cleaning, lubing and conducting properties were immediately apparent, and the Pot Cleaning Cap directed the spray where it was needed, and no waste puddles had a chance to collect on (or penetrate) any instrument's finish.

After years of buying assorted spray cleaners and achieving mixed results the answer arrived inDeoxIT. And without the usual waste thanks to the Pot Cleaning Cap the 5 oz can of cleaner should last a long time! (Which makes yours truly, Ol' Ebenezer Q Smallspender very happy, dontcha know)

Chalk one up for The STEW MAC DADDIES! (and Mommies, as the case may be)

Me? Lazy?

For those times when I just don't want to have to de-string/disassemble a guitar, this little gizmo is just the ticket. I have to be carefull to attach it properly AND have a rag handy to catch the overflow - but getting rid of "pot scratch" in only five minutes makes this tool a favorite.
