Jeff Yeager, the author of The Ultimate Cheapskate, knows exactly what to do with all those eggshells.
Try these money saving eggshell uses:
1. Less Bitter Coffee
Add an eggshell to the coffee in the filter, and your morning coffee will be less bitter. The spent coffee grounds, eggshell and biodegradable filter are then conveniently ready for the compost pile.
2. Splendid Seedling Starters
Fill biodegradable eggshell halves with potting soil instead of using peat pots to start seedlings for the garden. And an egg carton on the windowsill is the perfect way to start a dozen tomato seedlings in shells before transplanting to the garden in the spring.
3. Eco-friendly Household Abrasive
Shake crushed eggshells and a little soapy water to scour hard-to-clean items like thermoses and vases. Crushed eggshells can also be used as a nontoxic abrasive on pots and pans.
4. Crafty Projects
“Blow out” the inside of a raw egg and paint/decorate the hollow shell to make your Faberge eggs or other craft projects. Pieces of eggshell (plain or dyed) are also used in mosaic art projects.
5. Natural Drain Cleaner
Keep a couple of crushed eggshells in your kitchen sink strainer at all times. They trap additional solids and they gradually break up and help to naturally clean your pipes on their way down the drain.
6. Egg on Your Face
Pulverize dried eggshells with a mortar and pestle, then whisk the powder in with an egg white and use for a healthful, skin-tightening facial. Allow the facemask to dry before rinsing it off.
7. The Fuel of Tomorrow?
Just when your brain was totally fried by all my ingenious reuses for eggshells, researchers at Ohio State University recently discovered that eggshells might be the key to producing affordable hydrogen fuel. I’ve heard of walking on eggshells, but maybe some day we’ll be driving on them too.
