1. Use coffee grounds as fertilizer for plants
Coffee grounds are a very good organic fertilizer for plants. When decomposed, coffee grounds will provide many nutrients to help plants grow healthy and grow in the soil. This material also helps attract worms and reduce metal concentrations in the soil.
You can bury coffee grounds in the soil so that they decompose slowly, providing nutrients for plants.
2. Repel insects
Caffeine and diterpenes in coffee grounds are very effective in repelling insects. The aroma of coffee also scares these creatures. You can place coffee grounds in the house or burn dried coffee grounds to fumigate the house to help repel insects.
3. Prevent rust for metal objects
Coffee grounds contain a certain amount of essential oils that both prevent rust and help remove rust stains that have formed. You can dry coffee grounds and use them to polish utensils, especially copper utensils.
4. Use for skin beauty
Coffee grounds can be used to exfoliate, making the skin smoother. Applying coffee grounds to the skin and massaging will help remove dirt, remove dead skin cells, unclog pores, and make the skin smooth. In addition, caffeine in coffee grounds also has antioxidant properties, enhancing skin health under the effects of sunlight.
You can mix coffee grounds with coconut oil, olive oil and then apply to the skin to avoid skin irritation. Because coffee grounds are large in size, limit their use to exfoliate thin skin areas such as the face.
5. Deodorize
Coffee has a characteristic aroma that can eliminate unpleasant odors. You can place a few small cups of coffee grounds in the refrigerator to deodorize food, making the refrigerator cleaner and preserving food better. You can also mix coffee grounds with baking soda to increase the effectiveness of absorbing odors in the refrigerator.
In addition, when cutting onions and garlic and getting the smell of these foods, you can use coffee grounds to rub on your hands. This method will help remove the smell of onions and garlic very well.
