After the beetles have finished their work, usually 36 hours for a deer-sized skull, the skull is then degreased. This is necessary for a long-lasting quality skull. After degreasing the skull undergoes a whitening process. This process is superior to bleaching, which causes flaking. The end result is a clean, white, greaseless trophy skull. We will get your skull as white as possible, however, the degree of whiteness does vary depending on several factors, including the condition of the specimen, naturally occurring oils in the bone, and age of the animal.
