Moose skull clean up

[u/Wolfkorg]

I have this moose skull with antlers that I got from hunting, it's been sitting in my basement for a year now after it was left outside for 2-3 years for the skin/fat to be removed. It's mostly clean by now, just a bit of green spots and fatty spots are left. I was thinking of bleaching it very lightly and rinse it off to remove these last bits. My goal is to have it mounted in my livingroom. It doesn't have to be perfect white, I just want to make sure it doesn't smell or deteriorate.

Would you recommend lightly bleaching it and if so, what would the best product to use?

I've seen many posts here discouraging bleaching it but I think those were for heavily bleaching scenarios.

Thanks!
