I have a MIDI controller keyboard that I have cleaned in the past with disinfectant alcohol wipes, which I know is a bad idea because it degrades the rubber over time.

Well, the rubber on the pitch bend and modulation wheels has indeed degraded, and the surfaces texture is awful, uneven and sticky now. My fault... I know.

So does anyone know of any way to fix, or even improve, this kind of nasty rubber surface degradation once it occurs? Sanding? Applying oils? Is there any way I can even slightly restore these controls back to their original soft-touch rubbery glory?

I recently saw somewhere that gasoline can help. Might be total bullshit, or depend on the exact material. Might be worth trying on a very small area of the rubber surface. Outside in the shade. Gas fumes are bad.
