Caring for Rubber in Vintage Devices, the Curators' Way

Not just vintage devices - MIDI controllers I've bought in the last 10 years from Ableton (Push 2) and Keith McMillen have that wretched rubber that starts sticky, gets goopier, and attracts every mote of dust & hair from the surrounding air. Disgusting and makes them harder to sell 2nd hand IMO.

I was hoping the linked article would provide meaningful solutions, "storing in open air or a bag with holes" - that's what I already do - and "don't clean it, that just makes it worse" are pretty useless coming from 'experts'...
