You guys sure seem to make this process a lot hard than it should be. Put the head in a pot of water, bring to boil, add a little dish soap, adjust heat so it just simmers and doesn't boil over. After about an hour take the head out pressure wash the hell out of it. If still not quite clean, boil for a little longer and wash again. Process works the best on a fresh kill, if the skin/periosteum dries onto the skull, then cleanup takes more time and makes more work out of it. Best to pull the skin off the head same time you pull the skin off the critter, only takes 5 mins longer. Pull bottom jaw, take out eyeballs, and start boiling. Should be able to have a skull cleaned and in your bleaching agent of choice within about 2 hours. Maceration looks like a lot more work and smell but to each their own.
