I recently got this.... and from reading a lot around, I settled with 5ml per cup (236ml) for 5-10min. The only exception would be smooth skin acros which people suggested a 2-3min dip.
That stuff creeps me out...I'm sure I works good, but gross stuff to say the least. Do people just pour it down the drain when they are done, or is there a better way to dispose of it?
