SKULL CLEANING Instead of using beetles, we clean and degrease our skulls using a multi-step simmering process. We do NOT boil skulls- only simmer them- to prevent any skull deterioration. Every skull is whitened with organic hydrogen peroxide and sealed for a beautiful white finish that lasts. Ask us about hydro-dipping! We are proud to work with Liquid Ink Hydrographics in Middleton, WI for our hydro-dipping needs. It is an art in itself and we are blessed to be nearby one of the best in the business.
