Is there any way to restore sticky degraded rubber surfaces? (fedia.io)

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?

303 aerospace conditioner is what we use for raft rubber. Works for tires and a lot of plastics if they're not too far gone (needs original structure, can fix texture). To be clear though it's basically straight PFAS so if that is a concern I'd probably just try to fine a replacement part. A lot of electronics get broken cords so if you can find a busted one on eBay that's maybe the better choice.
