Skull was cleaned by the fly and maggot method in 2 garbage bags. horns were removed after about 3 weeks and came of easily and cleanly. I pressure washed the skull then used peroxide cream from a beauty supply to bleach. Skull is perfect albiet feels slightyl greasy. However my problem is with the horns. There is a definate hairy like outer covering attched to the inner core of the horn. Most of this just pulled off but where it was attched to the inner core has left a rough almost wire brush texture. some of it scraped off but not wanting to damage the hard core I quit trying with those methods to get it off and went to this forum as I was advised to do for help with this problem.Thanks for your answer and perhaps my explanation will help with the horn problem. I will look further into the foum to see if I can find an appropriate degreasing agent. Again thanks.
Got it "white" with peroxide 40% horns are off and came off easily. It is the Exterior of the horn that has the hairlike covering. As I said most of it came off just by a little pulling and scraping but still has bristle like areas that I am having the problem with. Again it is the loose horns exterior that I wish to clean properly and remove this hairy/bristly stuff.
