My friend sent me all his African skulls. What is the best way to get the horns off? Also there's a water Buffalo I know you can't get the horns off of that so how do I decrease it? My guess is it's not OK to put horns in the degreesing tank. I'm guessing to whiten the skull use the paste peroxide? There's a hippo in there and I know it will take months in the degreasing tank but does anybody have any pointers for me? And what on Earth would I charge for that?
