Ear wax is also called cerumen.
The ear canal cleans itself with a waxy secretion called cerumen. Sometimes, the wax builds up and causes symptoms, including mild deafness and a sensation of fullness inside the ear. Most of the time, this condition is harmless and the ear canal does not need to be cleaned. In some cases, the wax plug loosens and falls out by itself without the need for intervention.
However if excessive wax builds up, you are best leaving the job to a professional. There are reasons why we have been told since childhood "Do not put any thing bigger then your elbow down your ear"
