7. Fertilize Your Garden
Before using eggshells as fertilizer, be sure to rinse and remove the clear inner membrane of the eggshells and set them out to dry. Place the dry eggshells in a large and secure container. After filling the container with plenty of eggshells, mash them into fine bits with either a steel or wooden spoon. Once spring temperatures have softened the soil in your garden, sprinkle the ground eggshells into the soil; this will add a healthy dose of calcium carbonate.
6. Create a Non-Toxic Abrasive Cleaner
Say goodbye to chemical-based household cleaners that are tough on your hands and rough on your nose. There is a non-toxic compromise that involves, yeah, you guessed it, eggshells! Gather a dozen or so eggshells and place them on a baking sheet. You can either naturally dry the eggshells outside with sunlight, or put them in the oven for a few minutes on low heat. Using a mortar and pestle, coffee grinder or high-speed blender, blend the eggshells until they turn into a fine powder. In a mason jar, add three cups of baking soda, the cup of eggshell powder and mix them with vinegar or water. This formula works great on various surfaces, from pots and pans to shower doors and toilet bowl rings.
