The use of different detergents in skeletal preparations

Skeletal preparation has become an integral component within the field of forensic anthropology. The aim of this study was to determine which commercial detergent was most effective and efficient for use in skeletal preparation. The hind limbs of 24 pigs (Sus scrofa) and five detergents with bleaching agents and enzymes (Surf and Ariel), only enzymes (OMO Auto and Sunlight powder) or only bleaching agents (Sunlight dishwashing liquid) were used. Specimens were skinned and immersed into a pre-heated 6 L detergent solution or tap water and macerated at either 45 °C, 50 °C, 55 °C and 60 °C. When maceration was deemed complete any remaining soft tissue was manually removed under running tap water and the remains left to dry. A scoring system was utilized to assess the effectiveness and efficiency of each detergent. OMO Auto specimens only required a single day to complete macerate regardless of the temperature and these specimens constantly scored better than the other detergents used, thus making it the most effective and efficient detergent tested.
