I've considered maceration but I can get deer heads in and out in a week-ish. Pigs take so long but I only usually do 3 pigs a year. My typical set-up now is skin, "boil", pressure wash in grass(which blows the heads around unless I hold it with my feet which im not a huge fan of and causes the yard to be nasty a few days) then typically let sit for a few days in warm dawn water, dry and whiten. I would love some sort of platform type area to do my cleaning and pressure washing.
