Review (5/5): Great for whitening animal skulls/bones
I'm a naturalist and I preserve and articulate various animal skeletons for educational purposes. This product can be used after maceration to whiten bones. There are several tutorials online that will explain the process, but I can tell you that this works on both aged skeletons where the bones have been left in nature as a result of decomposition, and "fresher" skeletons that have not been exposed to the elements. It's highly effective and works for what I intended. Amazon offers a reasonable price compared to other resources.
