How to Repurpose Used Coffee Grounds into Natural Deodorant

I have always been interested in reducing waste and finding new uses for items that would otherwise be discarded. Used coffee grounds seem to be an item that many people don’t think twice about throwing away. However, with a bit of creativity, these grounds can be repurposed into a variety of useful products – including natural deodorant.

In this article, I will provide an in-depth look at how to transform used coffee grounds into an effective, all-natural deodorant. Below are the key topics I will cover:

Why Repurpose Coffee Grounds?

There are several great reasons to find new uses for spent coffee grounds rather than sending them to the landfill:

  • Reduces waste – Coffee grounds are one of the most common kitchen scraps that get thrown away daily. Repurposing them keeps them out of landfills.

  • Saves money – Making your own deodorant at home costs a fraction of what you’d pay for brand-name antiperspirant at the store. Reusing free grounds cuts the cost even more.

  • Avoids chemicals – Store-bought deodorants and antiperspirants often contain concerning ingredients like aluminum, parabens, and phthalates. Using all-natural ingredients allows you to avoid these.

  • Soft exfoliation – The coarse texture of used grounds makes them perfect for gently exfoliating skin. This can help eliminate odor-causing bacteria.

How to Make Natural Deodorant with Used Coffee Grounds

Making homemade deodorant with spent coffee grounds is a simple project with huge payoff. Here is an overview of the easy process:

Ingredients Needed

  • Used coffee grounds
  • Baking soda
  • Coconut oil
  • Essential oils (optional)
  • Glass jar or tin for storage

Step-by-Step Instructions

  1. Gather 1/4 cup of used coffee grounds. Dry them fully by spreading out on a baking sheet and baking at 300°F for 10 minutes if needed.

  2. Add the baked grounds and 3 tablespoons of baking soda to a small bowl. Stir well with a fork to combine.

  3. Melt 1/4 cup of coconut oil in a small pan or glass bowl. Add 2-3 drops of your favorite essential oil(s) like lavender or lemon if desired.

  4. Pour the melted coconut oil over the coffee ground mixture. Use the fork to continue mixing everything together until a thick paste forms.

  5. Scoop the finished deodorant into a glass jar or tin for storage. Allow it to fully cool and solidify before use. It will keep for several months.

  6. To use, simply swipe a fingertip amount onto clean underarms whenever needed for all-day odor protection.

And that’s it! Whipping up this frugal and eco-friendly deodorant takes just a few minutes.


There are endless options when it comes to customizing homemade deodorant:

  • Add more coconut oil for a smoother texture
  • Use arrowroot powder instead of baking soda for sensitive skin
  • Play with essential oil blends like citrus, floral, herbal
  • Mix in activated charcoal to help absorb wetness
  • Replace grounds with used black tea leaves

Benefits of Using This Natural Deodorant

Switching from conventional antiperspirants to this homemade coffee ground deodorant offers some great advantages:

  • No harsh chemicals – Store-bought deodorants often contain concerning ingredients, while this recipe uses only natural antimicrobial ingredients.

  • Gentle exfoliation – The used coffee grounds provide light physical exfoliation to help eliminate odor-causing bacteria when applied.

  • Long-lasting odor control – The baking soda reduces underarm pH to combat bacterial growth for all-day protection against unwanted smells.

  • Softened skin – The coconut oil moisturizes and smooths skin under the arms.

  • Economical – Making your own costs a fraction of high-end natural deodorants but works just as effectively.

  • Minimal waste – Repurposing used coffee grounds that would otherwise be tossed reduces waste being sent to landfills.

  • Customizable – You can tweak this recipe based on your own preferences and what works best for your body.

Storing Your Finished Deodorant

To get the longest shelf life out of your homemade coffee ground deodorant:

  • Store in an airtight container – This prevents the coconut oil from going rancid. Glass jars or tins with tight lids work best.

  • Keep in a cool, dry place – Heat and humidity can shorten the life of your deodorant, so stash it somewhere like a bathroom cupboard away from direct light.

  • Use a clean scoop – Never place dirty fingers into the jar, as bacteria will contaminate the product. Use a popsicle stick or small spoon instead.

  • Refrigerate in hot climates – If you live somewhere quite warm and humid, keeping the deodorant chilled can help it remain stable.

With proper storage methods, this simple deodorant should stay fresh for 2-3 months. If it becomesgrainy or separated, it’s time to whip up a new batch.

Troubleshooting Tips

Switching to natural deodorant can take some adjustment, but these tips can help you troubleshoot any issues:

  • Use less – Start with a very small amount and build up gradually. Too much can cause irritation.

  • Weather – More sweat in hot, humid weather may mean you need to reapply more frequently.

  • Detox – It takes the body time to purge built-up antiperspirant and normalize. Power through for a few weeks.

  • Shave less – Excessive shaving can worsen irritation. Try growing out underarm hair a bit.

  • Wash clothes – Kill odor-causing bacteria by washing shirts and dresses after just one wear.

Stick with this simple coffee ground deodorant for a few weeks, tweaking as needed, and soon you’ll wonder how you ever used anything else!

Final Thoughts

Whipping up natural deodorant at home using ingredients you likely already have on hand is a fun, empowering project. Finding ways to repurpose items like used coffee grounds reduces waste while saving money.
