There are several reasons to clean and preserve an animal's skull.

Steps

Part 1 of 2: Removing the Meat

Preserve the Skull Step 1

Step 1. Take precautions to avoid zoonoses

Animals can transmit many diseases to humans, such as rabies; they are called zoonoses and can remain active and transmissible even after the animal's death. It is of paramount importance to beware of such illnesses.

  • Wear gloves and wash your hands, arms and any part of the body that comes in contact with the animal's carcass very well.
  • It is highly recommended to wear a surgical mask during the skin removal process.

Step 2. Macerate the skull

Maceration is the technique of removing flesh from both the inside and outside of the skull by submerging it in water with an enzymatic laundry soap. There are several methods of doing this.

  • Cold water maceration takes time. The skull should be soaked in water at room temperature with a little soap for washing clothes specifically for cold water. These products have enzymes that break down organic matter and this is the safest method of cleaning the skull while leaving it intact. It can take days and even weeks to complete the process, depending on the size of the skull.
  • Hot water maceration consists of leaving the skull submerged in boiling water – without boiling – with an enzymatic detergent. You can use the stove to do this; the important thing is to pay attention to the skull, as leaving it too long or boiling it can cause the fat present to penetrate the bone and this will damage it.
  • Another way to remove the skin from the bone is to leave it on an anthill, taking care that other animals don't take it away – using a cage is a good idea. The ants will clean any and all of the flesh but leave the structure intact.

Step 3. Get rid of the fat

Remove it by soaking the skull for a few days in a mixture of water and a little degreasing dish detergent. This part is important, as the grease will start to give off an unpleasant smell and accumulate dirt on the surface.

  • Wear latex gloves to handle the raw material.
  • Change the water daily or whenever it becomes cloudy.
  • If after a full day the water remains clean, this step will no longer be necessary.

Most skulls used for preservation are from carnivorous animals, which have canine teeth and these teeth are usually smaller than the cavity in which they are located.
