How to remove black tar-like gunk from cat ears

This recurring dark, waxy buildup fills the crevices of the ear every couple of weeks. Trying to wipe it away with a Q-tip feels almost impossible because the debris clings like sticky tar. This leaves people unsure if the cat simply does not know how to clean their ears or if another issue is causing it.
