Wolf Medicine....your advice on many paths is one that goes without saying but when it comes to skulls ASK any OFFICIAL Scorer the preferred method for cleaning your trophy. Call ANY Musuem or ask any Osteologist the preferred methods of cleaning bones with minimal damage. Yes, there are many methods...maggots, ants, bury carcasses, use various forms of chemical maceration, use crustacea, bury in marine tidal zone, place in screen enclosures and drop off a pier, enzymatic methods, bury in sand boxes, use large quantities of manure, use alternative dermestid species, use sow bugs, use meal worms,etc,etc..
Boiling is probably the most common but definately the most damaging....especially by the novice.
