The Daily News, Nov. 15, 2006 By Sally Robinson and Keith Bly Earwax, also known as cerumen, is a thick, sticky liquid that has a very important job — to trap anything that flies, crawls or is blown into the ear canal, such as dirt, pollen, tiny insects and bacteria, and to keep it from going further into the ear, where it can cause damage. So what do you do about keeping your child’s ears clean and getting rid of earwax? In most children, you don’t have to do anything.
