Im working on a Large hog skull. After using the maceration process, and letting it sit in 90 degree water (Im in Florida) for a week and a half, with 1 water change, all of the meat, etc have come right off. I rinsed the skull well, and used a wire brush lightly, as it really wasnt needed, to get all the small remaining bits of meat off. I then cleaned off the container, refilled it with fresh water, and proceeded to dump 1/2 a container of Dawn dishwashing liquid into the fresh water. I soaked the skull for an additional 2 days in this degreasing solution. After 2 days, I took the skull out and put it in the sun to dry. After 3 days of drying, I notice the top skull to be very white and nearly ready for bleaching with peroxide, but the LOWER jaw has large grease stains, in several places, and actually has left a large 5" diameter grease spot on the concrete where it was sitting.
Will this grease on the lower jaw eventually be dissolved by the sun? Can I do something to help it go away so I can continue to the bleaching stage? Any advise would be greatly appreciated.
