The procedure for cleaning mammalian skulls with ammonium- hydroxide is given. Suitable for medium-sized rodents and marsupial or small but robust skulls, the process involves soaking the skull in concentrated ammonium-hydroxide for 24 hours and then boiling it in concentrated ammonium-hydroxide for 1 to 4 hours. Soft parts may be washed away and other tissue may be mechanically removed. Screens are useful for collecting separated bones and teeth.
