I'm new to the whole skeletonizing thing and Was wondering if anyone had and clues or ideas on what I could use to degrease a ribcage and keep all the cartilage in tact? My goal is to mount a few animals for educational purposes and would love it if the cartilage is still attached to the ribs. Also another question is what exactly is "BO"? I did a search on it and 144 pages came up where it detected every single word that has a bo in it. Any incite is greatly appreciated.
