Cleaning Skulls

This is a pdf file I found from a university for cleaning skulls I used to have some different links for this that I think were a little better , but can not find them so this will work some terms are bleaching skulls means use peroxide not bleach, to degrease skulls is dish soap (dawn) some colored dish soap may stain. Skulls that are split down the middle is a good sign they were not cleaned properly you see this a lot on buffalo skulls, I've used baking soda and dawn to clean and degrease before if you introduce air into the container before it is ready it will stain also I have only done minor cleaning never a full meaty skull, but if one is going to paint skulls this information is critical you must have a clean skull to paint on
