Modern day potentiometers are marvels of durability. After asking a few very similar questions, my conclusion was that cleaning and lubricating provides little or no benefit. Erratic behavior is usually due to component wear or damage and can't be improved by simple cleaning. Years ago I did tend to lube and clean pots. I originally looked for something called tuner cleaner which would clean, lube and disperse moisture. But, the old TV shop owner in my town pointed out that WD40 did exactly that and it was what he used. I stuck with WD40 after that. The problem is the lube attracted dust and dirt which greatly accelerated wear. Now-a-days it's a loosing battle. I haven't touched a pot for a long time. Beware of conventional silicone adhesives. They will release a corrosive substance during curing which loves to destroy electrical components such as servo pots.
