Cleaning and disinfecting Ostrich eggs in preparation for your egg art.
Household baking soda
Household chlorine bleach
High Speed Drill or Dremel to make holes in the egg shell
Cleaning out the eggshell:
I like to use my high-speed hand piece to drill small circular openings on both the top and bottom of the shell. The holes allow the contents to be blown out. Make sure the openings are large enough that when you or your helper blows on the egg its contents easily flows out but not so large as to detract from what you may want to design on the shell.
Using yours or a helper’s lungs, blow out the contents. I liken this to blowing up large balloons. Hence this is why I engage a helper. I also save the egg contents into a clean bowl for other uses.
Disinfecting Ostrich Egg:
Once the eggs have been blown out, I wash out any of the remaining material in a stream of lukewarm water in the sink then let the eggshell sit in a bowl to drain the water from the shell.
Always use caution when using household bleach. Wear grubby clothing. Bleach will splatter and remove the color on your clothing.
Following the initial washing I then put the eggshell in to a large container filled with chlorine bleach making sure to fill the egg with the bleach and that the solution is covering the entire egg. Use latex gloves as not to bleach your hands. This is a disinfecting process that will kill bacteria. After about five to ten minutes remove the shell from the solution drain and rinse off the bleach with clean running water.
Place the egg in another container with a solution of baking soda and water. This is about a half a gallon to a tablespoon of baking soda. Make sure the shell is, again, filled and fully covered, let the shell rest in the solution for a few minutes then remove the shell from the solution and again rinse off the solution from the shell with clean running water. This baking soda solution neutralizes the bleach.
Place the eggshell in a bowl or egg carton to allow the remaining moisture to drain and air dry. Once this process has been completed the shell is ready for your egg art masterpiece.
