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.

Good Idea

Thought this tool may save a lot of time in my workshop. So far, I've not found a pot that it will screw on. Yesterday, a wonderful Gibson 335 came in for a setup so I got out my pot cleaner cap out to try. Didn't even fit on the thread as their wasn't enough thread to bite. doh! I'm sure it will be useful, but only had it a couple of weeks and It doesn't fit alpha type pots. Good idea though. Will persevere with it...

Pot Cleaner Cap

I purchased the "Cap" to facilitate efforts to apply cleaner to the pots on my vintage guitar. It slipped right over the stems and made application of the cleaner simple and avoids making a mess from over spray. A good choice and nice tool to have available for maintenance of old pots.

Can't imagine spraying without it. Works perfect. Saves a big mess.

Excellent time saver for archtop guitars!!!

Wow....I really did not think this product would actually work but was willing to give it a try. I Always dread disassembling archtop components just to clean a pot or two. I used this to clean pots on a vintage 1960's Gibson and worked absolutely perfectly to clean scratchy pots. Turned a 1-2 hr job into 5 minutes!

Great for semihollows 'n more

Got this pot cleaning cap to do some maintenance on the guitars and old effects after spending a long time working on a 335 via F-holes. I should have ponied up for this piece a long time ago. If/when I lose this thing (about the size of a 1/4 socket), I'll replace it.

Good but...

I never noticed it doesn't fit Alpha pots (my fault) so ended-up making my own dowel, tube version. Still, worth having around for pots that will fit the tool.

Great Tool For A Common Problem!

Who hasn't heard a static crackle when turning the pots on an old guitar or amp, new ones too. Chances are, that it's a dirty pot that may only need a quick cleaning to function smoothly. The "Pot Cleaning Cap" is an essential tool that directs your DeOxit or other cleaner right where it's needed, inside the pot housing on the contacts around the shaft. The cap directs the cleaning solution cleanly, instead of spraying it uselessly all over the outside of your components. I used the cap immediately after receiving it and was able to clean up the sound of an old Teisco Amp that did nothing but crackle. Now volume change is smooth, and tone changes noiselessly. This is certainly an easy to use tool that any musician needs for a quick cleaning of their knobs.

I was mildly skeptical when I ordered this - because trying to get cleaner down the shaft of a pot never works! But this is fantastic! It works great for 3/8 x 32 pots but it works surprisingly well with other sizes as well (messier of course). I use it on every amp and effects pedal I service (put it somewhere safe though because it's easy to lose on a messy bench!).
