Before you empty those used coffee grounds into the trash, consider these clever household uses for them:
Uses For Used Coffee Grounds
- 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 lid. Work into wet skin, and rinse.
- 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.
- Neutralize refrigerator odors. Placing coffee grounds 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.
- Natural de-icer. Sprinkle leftover coffee 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.
- Dye Easter eggs or paper crafts. Soaking with coffee grounds can be used to give an “antique” sepia appearance to watercolor paper or easter eggs.
- Blind bake a pie shell. Believe it or not, you can even use coffee grounds 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 the coffee grounds don’t come into actual contact with the pie crust.
- Scour pots and pans. The gentle abrasive of coffee grounds can help in the kitchen to remove stubborn caked-on food from your pots and pans.
- Snail, slug, and cat repellent. In the garden, just mound up a barrier of coffee grounds around the plants which slugs and cats are attracted to. It will help keep them at bay.
- 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 the grounds in around the immature shoots.
- 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 daily.
