It's on there because of the frequency of patients who bust their ear drum 'cleaning out' the ear canal. You'd be surprised just how often that is. They go digging deep thinking they're doing something, then go too deep or get their arm jostled accidentally and its 'Oops! Look who won't hear anything out of their left ear for the rest of their life...'
If letting the shower water rinse out the inside isn't cutting it, buy an OTC inner ear wax immolient.
