I've read it's supposed to be quackery... usually I just pour 3% hydrogen peroxide in mine every once in a while... a throwback to having an double ear infection for a summer at 13 from the water park... doctor after doctor saw me, prescribing various otic solutions until finally one East Indian doctor took a look in my ears, told me to put peroxide in them for a week and it'd be gone.

Dag gummit... if he wasn't right... I've been keeping it up ever since... every once in a while.
