We have a nice pair of "rubberised" binoculars, but the "rubber" has

Dunno if it always happens with age, or just to items handled by certain

my old mice wheels go that way if left for a year or two.

I've seen it plenty of times with rubber pinch rollers in tape drives,
but it seems quite random and independent of use, storage conditions etc.

Sadly I don't think there's a cure - once it's started going like that
it'll just get worse :-(

My old mobile phone had a rubber coating on the back. It became hard and
shiny and grubby looking so I cleaned in with IPA. Which worked but it
then went soft and sticky.
