Eggs are daily used in mostly all of the kitchens at home and we throw all the shells in garbage without realizing how beneficial they are for us. Here are the reasons that can make you stop throwing the shells.

Fertilize the Garden

Rinse and remove the clear inner membrane of eggshells. Store dry eggshells in a large, secure container.Mash them down to fine bits with a steel or wooden spoon. Then you can load up on eggshells again. Once the spring temperatures soften the soil, you can sprinkle and mix the ground eggshells you’ve been saving into your garden for a great source of calcium carbonate for the soil. An added bonus: they reduce soil acidity.

Create a Non-Toxic Abrasive Cleaner

Firstly, collect the eggshells of about a dozen eggs. Once you’re ready to prepare the cleaner, wash the eggshells and line them up on a baking sheet. Dry the shells outside in the sun or on low heat in the oven for a few minutes. Use a mortar and pestle, coffee grinder or high-speed blender to blend into a fine paste. You should have about 1 cup of powder. In a mason jar, add 3 cups baking soda to the eggshell powder. To clean, just mix the powder with vinegar (or water). Use this formula on pots and pans (with baked-on food), shower doors (with months of gunk), toilet bowl rings and grout.

Remove Stains From Thermos

If you use a metal thermos, you’ve totally experienced this problem: A brown film on the inside of your favorite beverage container. And no matter how hard you scrub, there’s no diminishing the patina. Here’s a solution…you guessed it: eggshells. Add a combination of warm or hot water and crushed eggshells about a third of the way. Close thermos and shake well for a few minutes. The mixture should help break down stains.

Make DIY Sidewalk Chalk

You can make home made chalks by crushing eggshells with flour and food coloring.

Feed the Birds

When you have enough eggshells to cover a baking tray, bake them at around 250 degrees until dry. They will be brittle enough to crush easily. Spread the mixture in a feeder or on the ground for birds to munch on. It’s a great source of calcium for the birds—especially for females during the spring, prime time for laying eggs.
