Ear wax
May I suggest you try ear candles, the Chinese have been using them for hundreds of years, my own experience began with a new roommate, he asked me to aid him in using an ear candle for his ears, we made a small hole in a paper plate and stuck the bottom of the candle about 1 inch through the plate, he laid down on the floor, the candle tip placed in the ear canal and the paper plate protecting from ashes falling, we lit the candle, as it burned down it was circulating warm air through the ear, about 2 inches from the plate we pulled it out, the ear wax had drawn up into the candle, massive amounts, now I do both ears about every six months, works great.
