Over two-thirds of all Americans start their day with a cup of freshly brewed coffee, and the average American coffee fan drinks three cups of coffee a day. Each cup of coffee leaves behind used coffee grounds, and most of those grounds end up in the trash. But there is a better way to handle spent coffee grounds.

There are dozens of things you can do with spent coffee grounds from taking care of your home and garden to craft projects to personal care. Look through these ideas for coffee grounds uses to make the most of the waste from all those cups of coffee.

Personal Care Using Coffee Grounds

1. Coffee Scrub Skin Exfoliant

  • Let your used coffee grounds dry completely - do not use damp coffee grounds
  • Melt 1/2 cup coconut oil and let it cool slightly
  • Stir in 1 cup coffee grounds and 1 cup coarse salt
  • Add in cinnamon and vanilla extract as desired
  • Store in an airtight container.

This coffee scrubs mixture will exfoliate your skin and remove dead skin cells. The coconut oil acts as a pleasant moisturizer, leaving your skin smooth and soft and smelling fresh.

Your coffee grounds mixture is also a natural treatment for the dark circles under your eyes. Use a cotton swab or cotton ball, and be careful not to get coffee grounds in your eyes.

2. Coffee Bath Bombs

You can easily make fizzing bath bombs with your leftover coffee grounds. Simply mix together:

  • 1 cup baking soda
  • 1/2 cup citric acid
  • 1/2 cup corn starch
  • 1/4 cup Epsom salts
  • 3 tablespoons coffee grounds
  • 1 tablespoon almond oil
  • 1 tablespoon water

Press into a bath bomb mold and let dry for at least 24 hours. Store in an airtight container.

3. Coffee Soap

Since coffee grounds have great exfoliating properties, they make a great addition to homemade soap.

  • Start with glycerin soap base
  • Melt it as directed and add in dried used coffee grounds (You can add in other fragrances too)
  • Pour into a soap mold
  • Let cool completely before slicing into bars

4. Stimulate Hair Growth

This is one of the littler known uses for coffee grounds. Researchers have found that an excess of the hormone DHT can lead to hair loss. A study in the International Journal of Dermatology revealed that caffeine can block the effects of DHT and stimulate hair growth.

You can make a coffee rinse by steeping your used grounds in hot water for a few hours. Let it cool completely. Saturate your hair with this rinse and cover with a shower cap. Allow it to sit on your hair for 30 minutes and then rinse thoroughly with clean water.

5. Remove Odor from Hands

You know how difficult it can be to remove the smell of garlic or onions from your hands after chopping. Coffee grounds come to the rescue!

Rub the fresh grounds thoroughly on your hands until the odors are eliminated and then wash your hands with soap and water.

6. Cellulite Buster

The caffeine in coffee grounds can act as a skin tightener and reduce skin dimples. The American Society for Dermatologic Surgery suggests using massage to improve the appearance of cellulite, and a coffee scrub is a great to use for this. The combination of caffeine and massage can increase blood flow, improve lymphatic drainage, and tighten the skin.

7. Pots and Pans

Coffee grounds have a natural scouring ability. You can use them to get off caked on food and stains without having to use harsh chemicals or an abrasive cleaner like steel wool:

8. Deodorize Garbage Disposal

  • Combine used coffee grounds with Epsom salt and baking soda
  • Add white vinegar into the mixture

  • Use the frozen balls to run through your garbage disposal with cold water to eliminate odors from your kitchen sink

Dark wood furniture can look shabby with lots of scratches. You can eliminate scuffs and furniture scratches with coffee grounds:

Cleaning ashes out of a wood-burning fireplace can make a huge mess with dust flying everywhere. To keep the ash dust down, sprinkle cooled damp ground coffee over the pile of ashes. You can then scoop up the ashes without stirring up the dust.

11. Roach Bait

Use coffee grounds to make a roach trap to get rid of these pesky pests:

  • Fill a large glass mason jar halfway with water
  • Add a generous amount of used coffee grounds
  • Place the jars along your baseboards and walls

The roaches will climb up the jar attracted by the coffee smell and fall in. They are then unable to get out. Dump the jars each day and repeat until the roaches are gone.

12. Neutralize Odors

Dry used coffee grounds completely. Put them in an open bowl or jar in your refrigerator to absorb unsavory odors. It also works to eliminate chemical odors from new carpeting or furniture.

13. Slippery Sidewalks

Most people use salt on slippery surfaces to help it melt faster and provide some traction. Over time, salt can damage concrete and wood surfaces and is harmful for nearby plants. A gentler way to do this is with used coffee grounds.

  • Sprinkle them on your walk and driveway to provide traction and help the ice to melt

Coffee grounds work just like other organic plant material in your compost bin along with food scraps, kitchen waste, and grass clippings. They provide just the right amount of nitrogen, along with other nutrients including potassium and magnesium. Their coarse texture makes it easy to toss coffee grounds directly into your compost bins.

If you live in a coffee-loving household, you may find your own personal supply of coffee grounds can meet all your needs. But with all these great tips for using spent grounds, you’ll soon be looking for more.

Get Coffee Grounds from Work

Your workplace can be a great source of coffee grounds. Simply make it a habit to collect the used grounds from the communal coffee maker in your breakroom. If you make a new pot of coffee at the same time, you’ll also be rewarded with a fresh cup of coffee each time.

 

Local Coffee Shops

Ask at your local coffee shop or at a Starbucks near you. Many are happy to give out a bag or two of used coffee grounds to anyone who asks. And if that is still not enough, you can ask your neighbors or friends to store up their used coffee grounds for you.

Open Your Coffee Pods

If you use a Keurig or similar machine, you may find it challenging to salvage your used grounds. Figuring out how to extract the grounds not only gives you a steady supply, but also will allow you to recycle the plastic and aluminum components in each coffee pod. You can manually open up the pod, but there is a handy tool that makes the job easier. With a Recycle A Cup tool, you can separate the contents of the pod with a quick twist.
