i did my first buck and a bear skull for where i work....all i did was boil it til there was no meat left on it, then i took powdered bleach and peroxide , made a paste and waited..i reapplied it til all of the oils were out....used a blow dryer on it too, helped bring the oils to the surface.....you can use regular bleach, but my way is alot cleaner and you don' t have to worry about it getting on your antlers....
