the amount and consistency of earwax is genetically determined so there is really nothing you can do to limit what you make. earwax is not dirt. it is a very beneficial protective coating for the ear canal. when people attempt to remove it -- usually with frequent use of q-tips -- the body will just make even more since it is supposed to be there. q-tips are the most common cause of wax impaction since they tend to pack it deeper in the ear canal just like loading a civil war cannon. so if you use them (and i know you do). stop it. periodically if you do get an impaction you can safely flush out your ears with a gentle stream of warm water using an ear syringe.
what causes earwax build-up and what can i do about it?
