Use Leftover Coffee Grounds as Fertilizer

Speaking of waste, those coffee grounds arenโ€™t trash; theyโ€™re treasure! Especially if you have acid-loving plants like azaleas or blueberries. Mixing them with soil not only nourishes the plants but also maintains the soil’s acidity. And if youโ€™re into composting, adding coffee grounds can enrich your compost mix.

Use Leftover Coffee as Skin Toner

Next time you sip your coffee, remember it’s not just waking you up; it could be rejuvenating your skin too. Grounds make for an excellent scrub, eliminating dead cells, while its caffeine content boosts circulation. Plus, that leftover liquid coffee? It can double up as a skin-toning agent1.

Clean with Leftover Coffee

Coffee isn’t just for your morning boost; it’s a versatile household helper, thanks to its natural abrasive and acidic qualities.

Here’s how you can put leftover liquid coffee and coffee grounds to good use:

  1. Natural Cleaning Agent: The inherent abrasiveness and acidity of coffee make it an effective cleaner for various surfaces, including kitchen countertops.
  2. Scrubbing Power: Coffee grounds are excellent for removing stubborn, baked-on gunk from your pots and pans.
  3. Odor Absorber: Place some grounds in your fridge, trash bin, or any area plagued by bad smells to neutralize the odors.
  4. Grease and Stain Remover: The acidic nature of coffee can help in unclogging drains, slicing through grease, and lifting stains.
  5. Odor Neutralization: Coffee grounds contain nitrogen, which can eliminate odors by reacting with airborne carbon molecules.
  6. Natural Pest Deterrent: Coffee can keep unwanted garden visitors like ants and mosquitoes at bay.
  7. Wood Furniture Care: Minor scratches on wooden furniture can be diminished with a bit of coffee grounds.

Leveraging coffee in these ways not only maximizes its use but also offers eco-friendly solutions for everyday problems.

Store it & Reheat It

If you just want your coffee reheated, thereโ€™s a science to that too. Refrigeration followed by reheating on the stovetop (not too hot!) ensures safety without compromising too much on flavor. But remember, like most good things, coffee tastes best when fresh.

Often I’ll throw my leftover coffee into a mason jar and throw it in the fridge. And I don’t necessarily follow the “use within 24 hours” rule.


Is it okay to use coffee grounds directly on plants?

Yes, especially for acid-loving plants. However, moderation is key. I wrote a full guide on which houseplants like coffee grounds. You can read it here.

Can I use coffee grounds as a daily scrub?

It’s abrasive, so itโ€™s better to use it occasionally to avoid over-exfoliation.

Does reheating coffee make it more acidic?

Extended heating can lead to a more bitter and acidic taste.

Are there plants that donโ€™t benefit from coffee grounds?

Yes, not all plants prefer acidic soil. It’s best to research individual plant needs. Read my full post here.

How long can I store brewed coffee for reheating?

For optimal flavor, consume within 30 minutes. If reheating, store it in an airtight container (for example, a mason jar) the refrigerator and consume within a few days


Whether it’s your kitchen, garden, or beauty regime, there’s always a place for leftover coffee. But while it’s fun finding new ways to use it, letโ€™s not forget the joy of sipping a freshly brewed cup.
