Here are the top ten ways to use your leftover coffee grounds.

1. Energize Your Garden 

Coffee grounds are rich in nutrients that can benefit your garden or house plants. Incorporating coffee grounds into your compost pile or directly into the soil can enhance its fertility and provide essential minerals like nitrogen, potassium, and phosphorus. They can also help repel pests and ward off unwanted critters like slugs and snails. Additionally, coffee grounds can serve as an effective mulch, preventing weed growth and improving moisture retention in your garden beds.

Pro Tip: While coffee grounds are an effective fertilizer, we do not recommend using coffee to water your plants, as good old HO is still the better way to hydrate them!

2. Mix Your Own Natural Body Scrub

Coffee grounds possess exfoliating properties that can work wonders for your skin. Mix them with natural oils like coconut or olive oil to create a revitalizing body scrub (or try these five recipes to find your favorite). Gently massage the mixture onto your skin in circular motions to remove dead cells and reveal smoother, healthier-looking skin. The caffeine in coffee can also help stimulate blood circulation, leaving you feeling rejuvenated and refreshed.

3. Kill Odor

Coffee grounds have a natural ability to absorb and neutralize odors (which, on another note, is why storage of your coffee beans is so important!). Place a bowl of dried coffee grounds in your refrigerator, closet, or other areas with unpleasant smells, and let them work their magic. You'll notice that the coffee absorbs the unwanted odors, leaving behind a pleasant, earthy aroma. This simple trick can also be used to freshen up your car or remove lingering cooking smells from your hands.

4. Tackle Tough Stains the Natural Way

Coffee grounds can be a great addition to your cleaning arsenal. Their abrasive texture makes them ideal for getting to those tough stains and grime on pots, pans, and surfaces. Mix coffee grounds with a small amount of dish soap or baking soda to create a natural scrub. The grounds will help remove residue while leaving a delightful scent behind. Be cautious when using coffee grounds on porous or light-colored surfaces to avoid potential staining.

5. DIY Candle

If you're feeling crafty, coffee grounds can be incorporated into homemade candles to add a touch of warmth and aroma.

  • Mix dried coffee grounds with melted candle wax
  • Pour the mixture into a heat-resistant glass container with a wick
  • Let it set and trim the wick. As the candle burns, the fragrance of the coffee will gently infuse the air, creating a cozy ambiance.

These homemade coffee candles also make for thoughtful and unique gifts for your fellow coffee enthusiasts.


6. Repel Fleas from Pets

Coffee grounds can be a natural deterrent for fleas. Rubbing a small amount of coffee grounds onto your pet's fur can help repel these pesky insects. Ensure that the coffee is dry and be cautious with light-colored fur to avoid staining. However, it's important to note that while coffee grounds can provide temporary relief, they are not a substitute for proper flea prevention and treatment.

7. Bake Coffee-Inspired Treats

Extend your love for coffee to your culinary adventures! Used coffee grounds can add a delightful flavor and texture to various baked goods. From cookies and brownies to cakes and muffins, incorporating coffee grounds into your recipes can create a rich and aromatic experience. The grounds can be mixed directly into the batter or used as a sprinkle on top for an extra touch of coffee goodness.

 8. Enjoy Luscious Locks

Revitalize your hair with a DIY coffee hair mask. Mix coffee grounds with your favorite conditioner or natural oils to create a paste and apply it to damp hair. Leave the mask on for 15-20 minutes before rinsing thoroughly. The caffeine in coffee can help stimulate hair follicles, promoting hair growth and adding shine. It can also help darken and enhance the color of brown hair.

9. Boost Your Compost Heap

Coffee grounds are a fantastic addition to your compost pile. They contribute to the decomposition process by providing nitrogen, which helps balance the carbon-to-nitrogen ratio necessary for successful composting. However, it's crucial to avoid using coffee grounds in excess, as they can make the compost too acidic. Mix them with other organic materials like leaves, kitchen scraps, and grass clippings to create nutrient-rich compost for your plants.

10. Create Unique Art

Unleash your creativity by using coffee grounds as an artistic medium. Experiment with mixing coffee grounds with water or glue to create natural dyes or paint. The unique texture and earthy tones of coffee grounds can lend themselves to stunning artworks or illustrations. Whether you're an experienced artist or just exploring your artistic side, coffee ground art can be a fun and eco-friendly way to express yourself.
