I just cut the bottom off a 55 gal drum, put it on top of the old turkey/fish frier added some hydrigen peroxide and boiled for most of the day. Let cool and presure washed it off.
I wrapped some plastic around the antler bases and zip tied it before setting him in the water. then just kept the water at the top of his skull plate.
Sent the cape off and still have the antlers to look at untill the taxi is ready for them.
I could even just mount them to a board untill the cape is ready.
Turned out great, they could be bleached some more but, I was only cleaning them up for show and getting the smell under control!LOL
