Most people dump their coffee grounds in the trash as soon as the pot is empty. Once the coffee has been brewed, it’s easy to assume the grounds have done their job and there’s nothing left to do with them.

But used coffee grounds can still come in handy.

From cleaning messy cookware to adding to the compost pile, those leftover grounds have quite a few uses around the house. Some people also keep them for garden projects or homemade scrubs. If you already make coffee every morning, saving the grounds costs nothing and can keep a little extra waste out of the trash.

They Make a Handy Scrub for Tough Messes

The coarse texture of coffee grounds makes them useful for scrubbing certain surfaces. They can help loosen grime from pots, pans, sinks, and other hard surfaces where a little extra scrubbing.

You can mix a small amount of used grounds with dish soap and use the mixture on appropriate surfaces. Since the grounds can be abrasive, it’s best to avoid using them on delicate finishes or anything that could be easily scratched.

It’s a simple way to get one more use out of something that would otherwise be thrown away.

They Can Help With Unpleasant Odors

Coffee grounds are also commonly used to help with lingering smells. Dried grounds can be placed in a small bowl or breathable container and kept in areas such as the refrigerator or pantry.

Some people also use them near trash cans, in mudrooms, or inside shoes and gym bags. They won’t eliminate every strong odor, but they can be a handy option for everyday smells.

Make sure the grounds are completely dry before storing them in an enclosed space. Wet grounds can grow mold surprisingly quickly.

Gardeners Often Find Uses for Them

Coffee grounds are a popular addition to home gardens, but they aren’t a magic fix for every soil problem. Used grounds contain organic material and small amounts of nutrients, making them useful as part of a larger composting or soil-care routine.

Instead of dumping a large amount directly around your plants, mix the grounds into compost or use them in moderation. Fresh coffee grounds are more acidic than used grounds and behave differently in the garden, so don’t assume the two can be used the same way.

If you grow blueberries or other plants that prefer acidic soil, it’s still a good idea to test your soil and meet the specific needs of the plant rather than relying on coffee grounds alone.

Add Them to Your Compost Pile

If you have a compost pile or bin, used coffee grounds can be a useful addition. They break down along with other kitchen scraps, adding organic material to the finished compost.

You can add the grounds along with vegetable scraps, fruit peels, and other suitable compost materials. Used paper coffee filters can also often go into the compost pile if they’re made from plain, unbleached paper and don’t contain other materials.

Instead of sending all those grounds to the trash, you can turn them into something useful for your garden.

They May Help Discourage Some Garden Pests

Coffee grounds are sometimes used by gardeners around plants to discourage slugs, snails, and other unwanted visitors. Results can vary, so they’re better viewed as one small part of garden pest control rather than a guaranteed solution.

If you want to try them, scatter a modest amount around the plants you’re trying to protect and keep an eye on what happens. You may find that it helps in your particular garden, or you may decide another method works better.

The nice part is that you’re using something you already have instead of buying another garden product just to test it.

They Can Be Used Around Outdoor Areas

You may have also heard of people using coffee grounds to keep mosquitoes away. One method involves drying the grounds and burning them in a fire-safe container to produce smoke.

There isn’t a guarantee that this will keep mosquitoes away, and burning coffee grounds produces smoke that can irritate your eyes or lungs. If you try this outdoors, use a proper fire-safe container, keep it away from anything flammable, and never leave burning material unattended.

For a backyard gathering, commercially tested mosquito-control methods are a more dependable choice.

Turn Them Into a DIY Body Scrub

Used coffee grounds can also be mixed with other ingredients to make a simple body scrub. A basic mixture might include coffee grounds and a little coconut oil or another suitable skin-safe ingredient.

The grounds provide the gritty texture that helps remove dead skin from areas such as the hands, feet, elbows, or legs. Keep the pressure light, as rough scrubbing can irritate the skin.

It’s also a good idea to avoid using coffee grounds on broken, irritated, or freshly shaved skin.

Add Them to Homemade Soap

If you make soap at home, used coffee grounds can give certain bars a slightly gritty texture. Some soap makers add them as an exfoliating ingredient, particularly in bars meant for hands or other areas where a little extra scrubbing is useful.

The grounds can also give homemade soap a speckled appearance. Just be mindful of how much you add, since too many grounds can make a bar feel rough on the skin.

Use Them to Get Rid of Strong Food Smells on Your Hands

Chopping garlic, onions, or other strong-smelling foods can leave your hands smelling long after dinner is over. Coffee grounds can be used as a quick scrub before washing your hands with soap and water.

Rub a small amount between your hands and around your fingers, then rinse thoroughly. The grounds can help with lingering smells while also giving your hands a little scrub.

This is especially handy if you already have some used grounds sitting next to the coffee maker.

Be Careful About Using Them on Your Hair and Scalp

Coffee grounds are sometimes used as a scalp scrub because their texture can help loosen some buildup and excess oil. If you try this, use a very small amount and massage gently rather than aggressively scrubbing your scalp.

The grounds can be messy and may be difficult to rinse out, especially if you have long or textured hair. They also aren’t necessary for keeping your scalp clean, so a regular shampoo may be a better choice for many people.

If you do use coffee grounds on your scalp, stop if you notice irritation or dryness.
