Recommended way to clean a sticky pot

[TrueNorthStrong]

There’s plenty of info online, but given that this is on a very nice looking Monitor 100 I’d like to get a second opinion untainted by AI before I go about it.

The contrast adjustment was stuck fast on it at first. I removed the PCB from the housing, sprayed in some contact cleaner, and carefully applied force until it freed. Wiped it around, applied again, wiped, put back together and it was fine. Until this morning, it was stuck again and required a fair bit of effort to unstick.

I have Deoxit available and was thinking that might be a good next step. Open to suggestions!

Thank you.

This is usually caused by the shaft grease solidifying. I've used a couple of methods/ chemicals to fix this depending on how bad it is and the type of potentiometer. You need to take the pot apart to clean it properly. Sometimes, a q-tip or pipe cleaner and isopropyl is enough. Sometimes, I add heat, and sometimes I use a degreaser (super clean works well for me). You can also use an ultrasonic cleaner for the housing if you have one.. When done, you can re-appy some shaft grease and put it all back together. Make sure to use the correct deoxit for carbon track potentiometers if you plan to use it (fader deoxit / the green one)
