Re-use coffee grounds
Coffee grounds are rich in antioxidants, potassium, phosphorus, nitrogen, copper, magnesium and nutrients. Before being wasted, they are a great resource.
Home use
Anti-odor
Place the dried coffee grounds in a container near the fireplace, in the car, or in the refrigerator to remove odors. Rub coffee grounds on your hands to remove odors like onion odors.
Anti-mosquitoes
Place coffee grounds on aluminum foil and set them on fire. Alternatively, scatter coffee grounds in stagnant water (mosquitos’ den). The smell of coffee will drive mosquitoes away from the area.
Cleaning
Rub the coffee grounds on your house surfaces to remove dirt or ashes from the chimney. A great solution for removing dirt from hands as well. Be careful with lighter-colored surfaces as they may stain.
Ants ward off
Spread the dried coffee grounds in places where you find ants to ward them off.
Dehumidifier
Place the dried coffee grounds in a container and place it in the most humid places like the bathroom, kitchen, and living room, as well as in the refrigerator and car.
Tincture
Boil the coffee grounds in water for about an hour. You will get a natural dye for coloring natural fabrics, watercolor painting, or restoring scratches on furniture.
Personal care
Scrub
Mix coffee grounds with olive or coconut oil and massage the mixture over your body for a scrub and anti-cellulite effect. Also good for softening your feet.
Face mask
Mix two tablespoons of coffee grounds with some honey, milk, or yogurt (also vegetables) to make a mask that can soften and brighten your skin. Leave it on for 10 minutes and rinse off. Repeat once a week maximum, because it can stain the skin.
Hair
Mix the coffee grounds with some water and apply the mixture to your hair and wait about ten minutes. Rinse to get shiny hair and revive the dye color. Recommended for dark hair.
Gardening
Plants and vegetable garden fertilizer
Spread the coffee grounds on the soil of plants or vegetable gardens to nourish the potting soil. Good for plants that like acidic soils, vegetables, and fruit trees, e.g., azaleas, hydrangeas, parsley, basil, tomatoes, carrots, and zucchini.
Pesticide and repellent
Ward off slugs, ants, and worms naturally. Pour a handful of coffee grounds forming a circle around the plant.
Grow mushrooms
Place a transparent plastic bag inside a fruit box and pour the mixture of coffee grounds alternating with the mushroom mycelium into it. Close the bag and store it in a dark and cool place for about 15-20 days. When you start smelling the mushrooms, cut the bag with a small knife and expose it to sunlight. Harvest the first mushrooms after three weeks.
