Yup, turning the knob with no cleaner init can’t do anything but grind the dirt in deeper and possibly damage thepot. Deoxit is definitely the gold standard for low residue cleaners. Last timeI looked, Radio Shack actually had a couple of Caig products, but they weretiny cans and were a lot more money than you would pay online. Unless you arein a big hurry and have a Radio Shack around the corner, shop around.

You can turn that knob back for forth thousands of times and itwon't fix it.
But deoxit will!http://www.caig.com/

(ex: most of the time) buy some "real" tuner cleaner, "without lube" like from EZstreet, or blue shower, any of the expensive ones that don't melt plastic components. Dont get the cheap Radio Shack versions, or any of those from the american hard ware stores. They will ruin your Poly-800 forever. Then just spray it in the little holes on the volume pot, turn it from OFF to FULL volume about a hundred times fairly quickly. If you cant get the tuner cleaner, you can sometimes get it to work for very short periods of time by just the hundred or so quick turns.
If you cant get inside, you can spray a little right on the metal post under the plastic volume knob , and it will seep down into the pot. takes awhile of doing it a few times to get enough to seep in. OR, your pot is bad, and its a goner! LOL!!! 90% of the time it a little bit of dirt... typical "mature" keyboard stuff.
