Fire Starter

Forget about using boring old kindling to start your campfire. Pack some used coffee grounds into a cardboard egg carton, place a charcoal briquette on top, and light it up. The grounds will catch fire, providing a spectacular caffeine-infused blaze that would make even a pyromaniac barista proud.

Facial Scrub

Forget about those expensive spa treatments! Rubbing used coffee grounds on your face not only exfoliates your skin but also leaves you smelling like a java-infused superhero. Just make sure to rinse thoroughly to avoid being mistaken for a walking cappuccino.

Whirl used coffee grounds in a blender. Use on your skin as a facial scrub. Make sure to use in the shower for easy rinse off!

Lip Scrub

Chapped lips getting you down? Whip up a quick coffee grounds lip scrub to exfoliate away the dry skin. Mix the grounds with a small amount of honey or coconut oil, then gently massage the mixture onto your lips. Rinse off the scrub, and your lips will feel as smooth and kissable as a freshly brewed espresso.

Scrub Pots and Pans

Speaking of good exfoliation, try using used coffee grounds to clean that stubborn grease from pots. Use the coffee filter, too!

Kitchen Sink Cleaner

Is your kitchen sink looking more like a science experiment than a place to wash dishes? Sprinkle coffee grounds in the sink and give it a good scrub. The gritty texture will scrub away grime, and the coffee aroma will make washing dishes feel like a gourmet coffee break.

Rust Remover

Rusty tools getting you down? Sprinkle some coffee grounds on the rusty spots and add a few drops of vinegar. Let the mixture sit for a while, then scrub away the rust with a brush. Your tools will not only be rust-free but also smell like they’ve been sipping espresso in an Italian café all day long.

Keep Cutting Worms at Bay

Leave a pile around tomato plants to help keep cutting worms at bay. They don’t like the acid, but the acid is good for your tomato plants.

Clean Your Garbage Disposal

Coffee is a natural deodorizer. (It’s the acid.) If your garbage disposal has a funky smell, don’t panic! Dump some coffee grounds down there and let their magical aroma-masking powers do their thing.

Shower Deodorizer

Also works in the shower.

Make a Candle

This will give the scent of coffee throughout the entire house.

Coffee grounds can be used as fertilizer when growing vegetables such as potatoes, tomatoes, cucumbers, peppers, carrots, radishes, and beans. Root vegetables need magnesium and potassium, while nitrogen is essential for green plants.

Sprinkle some around the base of your plants and gently “rub” into the dirt. Just be sure not to add too much, as nitrogen means more green leafy and less yummy veggie.

Between Stones

Sprinkle used coffee grounds in between stepping stones or bricks.

Wood Stain

As an all natural wood stain, use this wonderful recipe.

Do Coffee Grounds Keep Mosquitoes Away?

Coffee grounds have a pungent, overpowering odor that mosquitoes don’t want to go near. Mosquitoes are repelled by all types of coffee, whether fresh, used or burnt. The most effective way to use coffee grounds as a mosquito repellent is to burn coffee grounds … yes, this actually works! I also love to sprinkle coffee grounds arounds my lemon balm plants, which surround my deck.
