This, Not That, Thursday – 5 uses for used coffee grounds

Something that never felt right to me was throwing away used coffee grounds. Many people wake up in the morning looking forward to their cup of coffee and then habitually toss the grounds into the trash without a second thought.

As it turns out, there are many wonderful things you can do with these spent coffee grounds. Before you throw out those grounds after brewing up your morning beverage, give one of these ideas a try.

1. Coffee grounds are wonderful at exfoliating your hair. 

To exfoliate hair, use 1/4 cup to 1/2 cup used coffee grounds, depending on hair length. In the shower, wet hair thoroughly. Massage grounds through hair focusing on the scalp. It helps to part the hair and work in sections. Once you have covered the whole scalp, thoroughly wet the hair again. Don’t try to rinse the grounds out as it won’t work. Use your shampoo to work up a nice lather. Then you can rinse it all out. A second shampooing may be necessary. Finish with your normal conditioner or apple cider vinegar rinse.

2. 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. Tomatoes love acidic soil!

3. Neutralize refrigerator odors. 

Placing them 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.

4. Weigh Down Ashes for Fireplace Clean-up:

If you have a wood-burning stove or fireplace, those old coffee grounds will become your best friend. When it is time to clean out the ashes, cover them with a layer of wet coffee grounds to moisten and weigh them down. This will greatly reduce the amount of ash that will float up and coat your living room when you scoop them out.

5. Pest Repellent

Snail, slug, and cat repellent. In the garden, just mound up a barrier of used grounds around the plants which slugs and cats are attracted to. It will help keep them at bay.
