For degraded rubberized surfaces on computer peripherals (I’m looking at you, Logitech) I now use WD40.
I soak pretty much the entire device in it and leave it overnight in the open. Most of the WD40 will have evaporated, leaving behind a film of dissolved degraded rubber and other gunk. You then use alcohol-free wet wipes to rub all that off and leave the device to dry.
I found that this approach requires less rubbing and scrubbing, useful for bigger batches. Don’t worry about the smell, it airs out in a couple of days.
