Before you empty those used coffee grounds into the trash, consider these clever household uses for them:
Uses For Used Coffee Grounds
1 As an exfoliant. The rough texture of the coffee grounds can be used on your skin as a scrub. Coffee scrubs are all the rage. Just mix 1/2 cup coffee grounds and 1/2 cup sugar (any kind) with 1/4 cup coconut oil in a small jar with a lid. Work into wet skin, and rinse.
2. Soil aeration and nitrogen boost for houseplants. Adding coffee grounds to your houseplants helps the pH balance (toward acidity) as well as increasing nitrogen and aerating the soil. Tomatoes love acidic soil!
3. Neutralize refrigerator odors. Placing them in the refrigerator acts as a natural deodorizer. The only thing you need to watch for is mold if you use damp grounds. Replace immediately with fresher grounds if it turns into a science experiment.
4. Natural de-icer. Sprinkle used grounds on your freshly shoveled walk or driveway to help melt the ice—it’s a natural and environmentally friendly way to add more traction underfoot. Just wipe your feet well before coming indoors!
5. Dye Easter eggs or paper crafts. Soaking in a solution with water and used coffee grounds can be used to give an “antique” sepia appearance to watercolor paper or easter eggs.
6. Blind bake a pie shell. Believe it or not, you can even use thems as the weight when you blind bake a pie crust. Just be sure to use a large enough piece of parchment paper or foil so they don’t come into actual contact with the pie crust.
8. Snail, slug, and cat repellent. In the garden, just mound up a barrier of used grounds around the plants which slugs and cats are attracted to. It will help keep them at bay.
9. Steroids for your carrot crop. Carrots love coffee grounds! They will grow larger and sweeter and the plants will have a greater yield. Just trowel them in around the immature shoots.
10. Clean your garbage disposal. Coffee grounds can clean and deodorize your garbage disposal. Just put the damp grounds in, run the cold water, and turn on the disposal. Note: do this only on occasion to freshen the disposal. It’s not recommended to run coffee grounds through the disposal daily.
11. Bonus Extra – Fishing secret: Mix a cup of used coffee grounds in with your bait worms to keep them alive and wiggling longer. Plus, fish—especially trout and bass—are attracted to coffee-scented worms.
