I have boiled it and sometimes just leave it soak in salt/water overnight to remove the final bit of meat/hair. I will soak it in a bleach/water solution overnight and then let it dry(just keep the antlers out of the bleach) for skull cap mount. You really don't need a bleached white cap if covering it with a mounting kit or fabric, just have to make sure the hide and meat is removed so it won't rot and smell over time.

Congrats on your first buck!!
