Ear wax, or [cerumen," is present in the ear on purpose. For the vast majority of people, wax removal is completely unnecessary. (Yes, you should pay attention to the warning on the Q-tips® box.)
The ears are designed to self-clean. They should almost always function normally by sloughing off ear wax as necessary, discarding it outside the ear. Sometimes people experience a hardening of ear wax.
