Re: Cleaning "slow" encoders and replacement parts

I'm under the impression that the Behringer ones are pots, but with no end stops, so they can keep turning.
Clicky rotary encoders operate two or more switches, as you turn them. The controller software has to keep watching the switches change, to work out the position.
I'm sure I've seen a picture of one of the BCR2000 encoders dismantled, and it looked like a carbon track, like the insides of a pot.
The switch cleaner idea seems like the best approach to me - I'm not sure you'd find the right replacement easily.
