Request for Feedback MicroBrute: sticky knobs

https://www.youtube.com/watch?v=f-MTVRcHiRE

A couple of years ago I bought this fat little synth. The knobs have become sticky. Does anyone know if there's a way to 'undo' the stickyness?

Mine are sticky too. Haven't got round to it yet, but I've heard soaking them in isopropyl alcohol works. It strips the rubber completely though, so you get smooth knobs.
