Whoops! Forgot about Mop N Glow. Don’t go home without it. It really works well on those antelope horns.
I do lots of euros, and a firm believer in Mop & Glow.
Skin & de-flesh head without cutting into/scratching the skull/SIMMER in water with Arm & Hammer liquid laundry detergent and Dawn dish soap. I bought the smallest/lowest pressure pressure washer I could find specifically for this. Simmer & wash/pick until ALL debris is removed, careful with the nose. Break the little round nodule on the back of the skull to pick out the brains with a wire hanger & wash. Once clean, change water and simmer with 40% liquid peroxide (can also add paste to the water, it'll dissolve) & protect bases of the horns from bleaching. When nice & white, I let it dry good for a day or two and then add a generous coating of Mop & Glow to the skull only. Works great. I have about 10 more heads in my freezers I need to get started on soon lol.
