Relatively new to the actual forums but not entirely to BAF. Just thought I would share my little discovery in the never ending quest to reduce sebum/ear funk/smelly cheese...whatever you may call it. I've found that a little tea tree oil massaged into the lobes while cleaning helps to keep things nice and bacteria free (which we all know is the actual source for the smelly part of sebum, bacteria eating those apparently delicious fat cells.) In my experience it has done away with the sebum issue almost entirely.
If you're the curious sort this is because tea tree oil is a natural antiseptic and has successfully been used as such for practically ever by the aboriginal peoples of Australia. And, imo, it smells really nice too!
Hope this helps some people and if anyone knows of a reason why this might not be such a great solution, please share...as far as the research I've done it seems to be a-okay but you never know.
