10 Brilliant Uses for Used Coffee Grounds in the Home

Coffee grounds often go straight from the coffee maker into the bin, but they can actually be incredibly useful in many areas around the home. From gardening to cleaning and even beauty, used coffee grounds can be repurposed in eco-friendly and practical ways. Here are ten fantastic uses for used coffee grounds that help you save money and reduce waste.

Our coffee expert, Aimee at Adams & Russell Coffee Roasters said

“Used coffee grounds are one of the most versatile household materials. They offer excellent natural properties for gardening, deodorising, and even beauty treatments. Plus, they’re an easy way to reduce waste.” 

 1. Nourishing Garden Fertiliser

Coffee grounds are rich in nitrogen, phosphorus, potassium, and other minerals that benefit plants. When added to compost or sprinkled directly into the soil, coffee grounds can help plants grow more robustly. They also attract earthworms, which aerate the soil and boost its health, creating an ideal environment for plants to flourish.

 2. Natural Pest Repellent

Garden pests, particularly slugs and snails, tend to avoid coffee grounds due to their texture and smell. Spread a thin layer of grounds around plants to create a barrier against these unwanted visitors. The strong scent of coffee also helps deter ants and even cats from disturbing your garden beds.

 3. Deodoriser for the Fridge and Freezer

Similar to baking soda, used coffee grounds can absorb odours in the fridge and freezer. Simply place a small bowl of dried coffee grounds on a shelf, and let them neutralise strong smells from foods like onions or fish. Replace the grounds every couple of weeks to maintain freshness.

 4. Natural Scouring Scrub

Coffee grounds have an abrasive texture, making them ideal for scrubbing stubborn stains off pots, pans, and kitchen surfaces. Mixed with a small amount of dish soap, coffee grounds can act as a natural scrub to help remove grime without leaving scratches on your cookware.

 5. Eco-Friendly Drain Cleane

Coffee grounds can help keep your drains clear when used sparingly. Sprinkle a small amount of used grounds followed by hot water into your kitchen sink drain to help remove grease and reduce odours. However, be careful not to use too much as an excessive amount could clog your pipes.

 6. DIY Coffee Candle

For a cosy, coffee-scented candle, place dry coffee grounds at the bottom of a candle container, then pour melted wax over the top. As the candle burns, the coffee grounds will release a pleasant aroma. This is a great way to add a warm, earthy scent to your home while also upcycling coffee remnants.

 7. Natural Exfoliating Body Scrub

Coffee grounds are a popular ingredient in homemade beauty products, especially body scrubs. The gentle exfoliating properties help remove dead skin cells, leaving your skin soft and refreshed. Simply mix coffee grounds with coconut oil or olive oil and a dash of sugar for a natural, spa-quality scrub.

 8. Repel Fleas from Pets

A surprising but effective trick is to use coffee grounds as a flea repellent for pets. After shampooing, rub coffee grounds through your pet’s fur, then rinse thoroughly. This can help keep fleas at bay, but always check with your vet first, as not all animals may tolerate coffee grounds well.

 9. Odour Control in Shoes and Gym Bags

Used coffee grounds are an excellent solution for absorbing odours in shoes, gym bags, or any other closed container where unpleasant smells can accumulate. Place dried coffee grounds in a small cloth or paper sachet and insert it into the item. Replace it every couple of weeks for consistent odour control.

 10. Furniture Scratch Repair

If you have dark wooden furniture, coffee grounds can be used to mask small scratches and imperfections. Mix grounds with a small amount of water to create a thick paste, then rub it into scratches using a cotton bud or soft cloth. Let it sit for a few minutes before wiping off excess grounds, leaving your furniture looking refreshed.

Used coffee grounds are a simple but versatile resource, offering a host of benefits in everyday life. From enhancing your garden to making a difference in beauty routines, these small changes can contribute to a more sustainable and creative household. Next time you finish a cup, think twice before throwing away the grounds—you might just find a practical use right at home.
