How to Reuse Your Leftover Coffee Grounds

Come to my house right now and you’ll probably find me with a cup of coffee in my hand or resting nearby. It’s not really surprising that I go through a ton of coffee grounds. My coffeemaker grinds the beans fresh for each cup of coffee and I have to clean out the filter with every cup. Instead of dumping out my coffee grounds into my compost container, I’ve discovered new and interesting ways to reuse your leftover coffee grounds. If you don’t grind your own coffee beans, you may be tempted to after reading these hacks!

Reuse Your Leftover Coffee Grounds

I found out recently that you can reuse coffee grounds to clean up vomit. I have to say that as a parent, I have an intimate relationship with both coffee and barf, so this little factoid intrigued me. A lot. I already knew that coffee grounds are a natural deodorizer but this was a new use I was not familiar with:

Using coffee grounds to clean up vomit

Step 1: dry coffee grounds in the oven, on a cookie sheet, and store them in a paper bag until the moment of truth.

Step 2: hold hands out, mouth open in a silent scream, watching but not able to reach in time the child who is projectile vomiting on the new rug.

Step 3: retrieve the bag of used but now dry coffee grounds. Sprinkle them liberally on the ‘puddle’. Let it sit. The grounds will a) soak up a lot of the liquid, making it easier to clean up and b) deodorize the carpet in the process.

Now, on to some less gross uses for your coffee grounds!

Do you compost?

Used coffee grounds sprinkled regularly into your compost heap or container will help to balance the pH levels in your compost. This helps to degrade the food waste more quickly. As a bonus, the grounds help with the smell. As an EXTRA bonus, coffee grounds will attract the worms that will also help in the composting process.

Other smells you could do without

The deodorizing effect of used coffee grounds can be used in a variety of other ‘high scent’ environments:

  • Your refrigerator – no need for baking soda. Just fill a cheese cloth with dry grounds and leave the bag in the refrigerator.
  • Your outdoor garbage can/dumpster – fill some old tights with dry grounds and hang them inside the cans: instant air freshener.
  • Cooking smells on your hands – when you cut up onions or garlic, there is little that can remove that powerful smell. Take some grounds, add a little water and rub it into your hands. Rinse with cool water and you’re back to smelling like you.
  • Stinky shoes – put dry grounds in a cheesecloth and place them in the shoes at night. By morning, you and your shoes should be ready to start the day.

Keep the plants, lose the pests

Do the neighbourhood cats like your garden? Sprinkle used coffee grounds liberally around your plants and flowers and most felines will step away. Apparently, ants and slugs aren’t fond of the smell or the texture either so up the amount in areas of your garden that see a lot of traffic from these pests.

Adding coffee grounds to your garden has the added benefit of being good fertilizer for all plants but in particular ones that are high in acids, like tomato plants, roses and hydrangeas.
