I know there are lots of threads on this common issue, but I've only read one where it was mentioned that you can take the pots apart.
While it looks like I can find these pots new, I wanted to see if I could fix mine properly and permanently.
I took some pictures just to show it can be done.
My procedure:
Take the back off the pots by carefully prying back the locking tabs.
One of the pots (500k ohm) can come completely apart, so it was easy to clean. Fortunately, this was the really gummed up one. I cleaned the shaft with 99% alcohol and used deoxit on the contact wiper. After drying and checking the resistance, I put it back together.
The other pot (500 ohm) was pressed together so I couldn't remove the shaft. However, by slowly working alcohol into it I am fairly certain that I've gotten most of the gummed up material. This took a while as I wanted to be sure.
I then reassembled the pots and put a tiny drop of Teflon dry lube on shafts. I worked this in a bit and both pots are totally free now.
I'll see how it is in a week or so, hopefully the stickiness doesn't return. I'll report back if there are any problems.
