Talked with McKenzie about preserving velvet on antlers. There taxidermist recommended there ult acid so i bought a quart. The directions don't say anything about neutralizing after they come out of the pickle. The velvet is hard on the antlers. Do I need to neutralize them after they come out of the pickle and do i need to do anything else to tan them? I don't have a lot of experience pickling due to using an auto tanner. My client does not want to spend the cash on getting the antlers freeze dried. Any help would be greatly appreciated.
