10 Uses For Coffee Grounds



Every coffee lover has an abundance of coffee grounds, but most of us just let them go to waste. Instead of tossing those grounds, did you know there’s a bunch of different uses for them?

Instead of tossing them in the garbage, consider reusing them! When you’re coffee’s done, simply spread the grounds out on a piece of parchment paper and allow them to dry, then place them in an airtight container and seal, storing them for later usage.

You’ll be able to use coffee grounds in cooking, cleaning, gardening, and more! Below are are our ten favorite ideas, so be sure to check them out!


In The Garden

When it comes to coffee grounds, they are perhaps the most well known for providing rich nitrates in garden soil. Adding used coffee grounds to a watering can can or applying directly to the soil can get this vital nutrient to your plants quickly and efficiently!

Did you know? Adding coffee to hydrangea plants can even color the blossoms a vibrant blue hue. The coffee grounds drastically reduce the pH in the soil, allowing the plant to create gorgeous blue flowers.

In Cooking

Another common use for coffee grounds is in cooking. Add a teaspoon or two of coffee grounds to chocolate cake mix to give it a richer taste, or add them into meat marinades in order to add a tenderizing factor.

A marinade of maple syrup, coffee grounds, and brown sugar creates a delicious sweet bacon, perfect for Sunday morning with eggs, or on a Friday night burger. Try adding some cooled coffee to a coffee cake, or mix it in to a cool cream cheese icing for a cake your friends and family won’t be able to get enough of.

With coffee and cooking, the most important thing is to experiment. You never know what flavors coffee might bring to the surface, so try it with everything!


To Kill Your Dog’s Fleas

Did you know? Some coffee grounds mixed into your dog’s shampoo, or used as a scrub after a bath and then thoroughly rinsed out, can kill any fleas your buddy may have picked up, and will help prevent them from coming back, too!

To Keep Your Cat From Using Your Garden Bed As A Litterbox

We work hard on those gardens gorgeous, and while our feline friends may think they’re helping us out by, uh, fertilizing them, it’s not so aesthetically pleasing to find a gift from your cat in with the hydrangeas. In order to keep this from happening, mix some coffee grounds with some dried citrus rind and sprinkle it in your flower bed.

These two things together should discourage kitty from using your prized garden bed as a litterbox, and keep your flowers looking and smelling fresh!


To Eliminate Odors In Your Fridge

We all forget to clean out the fridge here and there, and unfortunately, this can mean that the fridge can start smelling not-so-fresh. Fortunately, used coffee grinds can help you out there! Keeping dry, used coffee grounds in the fridge can have the same effect as a box of baking soda, absorbing bad smells and keeping things smelling clean and fresh in your fridge.

To Eliminate Odor From Your Hands

When cooking, we all end up having to interact with some smelly ingredients from time to time! Garlic, while one of the tastiest things you can put in a dish, leaves your hands smelling icky, even after washing with soap - and the same goes for onions!

While these smells are great in your food, they’re not so much on your hands, and you’ll want to get rid of them before dinner is served. To take care of this, keep a small bowl of dry coffee grounds underneath your sink, and quickly rub your hands with a small portion of them after handling stinky ingredients. Quickly rinse your hands and then wash with normal soap, and the scent will disappear!


To Scour Cast Iron

If you’ve ever had a cast iron pan, you’ll know that washing them with water is a big no-no. While traditionally scoured with salt, you can also scour them with dried, used coffee grounds.

Just add a cup or so of them into the pan, and scrib with a cast iron scrubber, wiping it clean afterwards, just as you’d do with salt!

To Clean Your Fireplace

If you have a wood-burning fireplace, you’ll know that cleaning wood ash can be entirely frustrating, as it’s so light that sometimes it just attempts to float away in clouds when you move it around.

To remedy this, cast some dried coffee grounds into the ash. This will weigh it down, and allow you to sweep it up much more easily.


To Naturally Repel Snails

Did you know? If your garden has a snail problem, you can use coffee grounds as a DIY snail repellent. Just scatter coffee grounds around the border of the area of ground you’re trying to protect, and the snails will stay away. This method can also be used for any slugs chomping on your garden vegetables, or even to control ant infestations.

To Naturally Discourage Mosquito Breeding

Mosquitos can be a big problem in hot, humid places. If you’d like to discourage mosquito breeding and you live near still water, fortunately, there’s something you can do about it. Take your used coffee grounds and cast them into the still water, and that will encourage the mosquitos to think twice before breeding there.


Whoa! Who knew there were so many things to do with coffee grounds? These ideas are some of our favorite, but they’re actually only a few of the possibilities that present themselves when looking to give second life to your favorite morning cup of joe.
