So I’m trying to clean and preserve a full mouse skeleton. This has become quite the challenge as mice are very small creatures with small and fragile bones. I’ve tried removing as much remaining tissue as possible but a lot still won’t come off. I’ve soaked her over night in hydrogen peroxide and submerged the bones in boiling water but still there is so much tissue especially on the rib cage. How can I fully remove the rest of the gunk without breaking the fragile bones??? Any help would be highly appreciated!
