Prior to becoming a Krazy Coupon Lady, if anyone had told me that I would be saving eggshells—I would’ve told them they were crazy! But for every coupon I use and every dollar I save—I’m still constantly on the lookout for even more ways to recycle and reinvent (in order to save, of course!). Every time I use at least two or three eggs, I bake them for about 20 minutes at 250 degrees to get rid of any bacteria so that I can recycle the eggshells for other applications. Here are 10 alternative uses for eggshells that will stretch your dollar even further!

1. Enhance your dog’s diet

Did you know that eggshells are known for their calcium benefit? Grind the eggshells with a rolling pin into a fine powder and add them to your dog’s food to provide needed calcium for their teeth and bones.

2. Boost your houseplant’s health

The calcium in eggshells also helps to boost plant nutrition. Crush the shells, add them to a glass of water, and then water your plants. Plant food is expensive, so give this a try!

3. Scrub your pots and pans

Eggshells are great abrasive agents. Crush them and use them to scrub burnt and stuck food from your pots. I’d much rather use a natural abrasive than have to purchase special (and expensive) cleaners for specific items.

4. Make a facial mask

Eggshells contain healthy nutrients for your skin. Crush your eggshells into a fine powder and mix with the egg white using a whisk. Apply the mixture to your face and allow it to dry. Rinse for a healthy, skin-tightening alternative to a spa treatment!

5. Remove splinters

No matter how little opportunity there is for it, my kids always end up with splinters in their fingers a couple of times every year. Instead of dealing with the fuss of an upset child over the pain of removing a splinter—ease their fears by applying some of the egg membrane to the splinter area and the membrane will draw the splinter out. No pain (and no fighting with squirmy kids).

6. Sharpen your kitchen equipment

Freeze your eggshells, and when the blades of your blender or food processor get dull, add those eggshells with water and then run the equipment. This will sharpen the blades (for free).

7. Remove coffee and tea stains

Have a favorite cup or pitcher that’s stained from coffee or tea? Remove the stains by mixing eggshells and water, and then let it sit in the cup or pitcher for a few hours. The eggshells absorb the stain!

8. Treat minor skin irritations

Place an eggshell in a small container of apple cider vinegar and let it soak for several days. Rub the mixture over the irritated or itchy skin (it’s a great alternative to bug bite ointment!).

9. Cat deterrent for your garden

My neighbor’s cat loves to use my flower garden as a litter box. If you’re in a situation like me then you should try spreading eggshells around your precious plants to keep the cats away. They won’t like to step on the shells and will find somewhere else to go.

10. Remove the bitter taste in coffee

Place crushed eggshells in your ground coffee before brewing it to remove the bitter taste. Then recycle the eggshells and coffee grounds in your compost heap!
