A mild detergent solution can effectively remove dirt without compromising the bone’s integrity. For tougher stains, a specialized bone degreasing solution can prove invaluable. Hydrogen peroxide, when used cautiously, can help whiten bones that have been discolored over time. Remember to follow the instructions for each solution carefully to avoid any potential harm.
Preparing Bones for Cleaning
1. Remove Soft Tissue
The first step in cleaning bones is to remove any remaining soft tissue. This includes skin, muscle, organs, and connective tissue. The most effective way to do this is to simmer the bones in a pot of water with a little bit of dish soap for several hours. The simmering water will help to loosen the soft tissue, making it easier to remove. Once the bones have simmered, use a pair of tweezers or a sharp knife to carefully pick off any remaining soft tissue. It is important to be gentle when removing the soft tissue, as you don’t want to damage the bones.
2. Defleshing
Once the soft tissue has been removed, the bones can be defleshed. This involves removing any remaining bits of muscle or skin that may be still attached to the bones. The best way to do this is to use a pair of sharp scissors or a scalpel. Carefully cut away any remaining flesh, being careful not to damage the bones.
3. Degreasing
The next step is to degrease the bones. This involves removing any remaining fat or grease from the bones. The best way to do this is to soak the bones in a solution of water and degreaser for several hours. A good degreaser to use is Dawn dish soap, which is effective at removing grease and grime. Once the bones have soaked in the degreaser solution, rinse them thoroughly with water and pat them dry.
4. Bleaching
The final step in preparing bones for cleaning is to bleach them. This involves soaking the bones in a solution of water and bleach for several hours. The bleach will help to whiten the bones and remove any remaining stains. Once the bones have bleached, rinse them thoroughly with water and pat them dry.
Removing Soft Tissue
Removing soft tissue from bones is a crucial step in the preservation process. The presence of soft tissue can attract pests, bacteria, and insects, leading to rapid decomposition. Proper removal ensures that the bones are clean, durable, and aesthetically pleasing.
Manual Removal
The most common method of soft tissue removal is manual dissection. Using a sharp knife or scalpel, carefully remove the soft tissue from the bone surface. This technique requires precision and attention to detail. Avoid damaging the bone during the process, and be patient to ensure thorough cleaning.
Chemical Removal
In certain cases, chemical agents can be used to assist in soft tissue removal. Enzymatic solutions or diluted bleach can effectively dissolve soft tissue. However, extreme caution is necessary when using chemicals. Follow the instructions carefully and wear appropriate protective gear. Prolonged exposure or improper application can damage the bone or result in hazardous waste.
Other Methods
Alternative methods for removing soft tissue include boiling, maceration, and dermestid beetles. Boiling involves submerging the bones in boiling water, which helps to loosen and remove soft tissue. Maceration involves soaking the bones in a water solution for an extended period, allowing the soft tissue to decompose naturally. Dermestid beetles are insects that specialize in consuming dried flesh, making them effective for removing small amounts of soft tissue from bones.
| Method | Advantage | Disadvantage |
| Manual Removal | Precision and control | Time-consuming |
| Chemical Removal | Effective and efficient | Potential for damage or hazardous waste |
| Boiling | Simple and inexpensive | Can damage delicate bones |
| Maceration | Gentle on bones | Time-consuming and requires controlled conditions |
| Dermestid Beetles | Effective for small amounts of tissue | Requires specialized equipment and handling |
Degreasing and Maceration
Degreasing is the process of removing the fat and grease from bones. This is important for two reasons: first, fat and grease can attract pests and bacteria, which can damage the bones; second, fat and grease can make the bones difficult to work with. There are several ways to degrease bones, but the most common method is to boil them in water with a degreasing agent. Degreasing agents can be purchased from most hardware stores.
Maceration is the process of removing the flesh from bones. This can be done by soaking the bones in water or by using a maceration solution. Maceration solutions are available from most scientific supply companies.
Maceration Solution
Maceration solutions are typically made with water, dish soap, and baking soda. The water helps to soften the flesh, the dish soap helps to break down the fats and proteins, and the baking soda helps to neutralize the acids. The bones should be soaked in the maceration solution for several days, or until the flesh has completely decomposed. Once the flesh has decomposed, the bones can be removed from the solution and rinsed with water.
The table below provides a summary of the different methods for degreasing and macerating bones:
| Method | Pros | Cons |
|---|---|---|
| Boiling | Fast and easy | Can damage bones |
| Simmering | Gentle and effective | Takes longer |
| Soaking | Prevents damage to bones | Takes longer |
| Maceration | Removes all flesh | Can take several days |
Bleaching Bones
Once degreased and dry, you are ready to optionally bleach your bones using hydrogen peroxide (H2O2). Make sure you wear gloves while working. Dilute the hydrogen peroxide 50/50 with water and submerge your bones in a sealed container to soak for 24 hours.
Caution
Hydrogen peroxide is an oxidizing agent that can cause skin and eye irritation, so it is crucial to handle it with care. If you come into contact with hydrogen peroxide, flush the affected area with water immediately.
