The oily substance is just skin oil that has permeated the membrane over time.
Oil goes through dirt stays on the button sides. Can't stop it, it will happen over again. You just have to do it again...
It looks like silicon grease, dad used to give them to me to clean if anyone brought theirs to him for repair.
Bit like air getting out of cheap bicycle inner tubes, bought some this summer, things are flat in three weeks! No punctures, and the valves are good,
