Best ways to remove velvet from antlers?

Yup. It's an old Indian chefs secret that he only tells when he's drinking..

I assume you are talking about taking velvet off a deceased bucks rack?

I play around with taxidermy part time. I have stripped velvet racks several times, however it's always when the velvet is really dry and about ready to rub off anyway ( sometimes a guy will shoot a buck in velvet, then later decides he prefers a clean rack and wants it removed) What I do is soak in a tub of water with a cup of Clorox bleach over night. The bleach softens up the velvet and removes most, or all the smell. If you are looking to remove velvet that was still pumping lots of blood ( like a buck that died in mid July) I believe there are some chemicals that can be ordered in my taxidermy books that help make it easier. I'll check into it. However if a buck dies in July, their racks are best preserved by freeze drying, if you strip the velvet the points will be very soft and porous and will break easily.

If you remove velvet from antler that are not "hard" or fully developed you will find the antler will dry very porous. For taxidermy purposes you will not get satisfactory results staining this antler. For hard antlers in late stages of velvet , soak antlers for several days in water with a box of borax mixed in for control of smell. 5 days is usually sufficient and then pressure wash without heat.

I've boiled mine with good success.  The same way you would boil a skull.

If they are full of blood its also easy to slice a little and peel like a bannana

I have used a power washer with good success on late season antlers that were covered in velvet.
