Simple & Easy Homemade Mouthwash Recipe

Easy Homemade Mouthwash Recipe

One of my all time favorite hobbies is antique and thrift shopping. While I was out hunting for secondhand finds recently, I found this gorgeous decanter at an antique shop a couple of weeks ago. My mom had this great idea to fill the decanter with mouthwash and store it in the bathroom. What a fun way to repurpose such a gorgeous find, right?! I’ve spent the weekend experimenting with various DIY easy homemade mouthwash recipes to find one that I really liked.

Why did I choose to make homemade mouthwash rather than purchasing store bought? Well, I’m trying my best to reduce waste in my home, and I figured the plastic mouthwash bottle is one less thing we could keep around the house. I haven’t seen natural mouthwash available in plastic free packaging at the grocery store unfortunately. The second, more important reason is because I’m trying to avoid the chemicals (Sodium Benzoate, Triclosan, SLS, Alcohol) often found in conventional store bought mouthwashes. I prefer to be able to pronounce all the ingredients in my household products, especially those going into my mouth! Another benefit of homemade mouthwash is that it’s dirt cheap to make.

UPDATE: This blog post was first written four years ago, and finally in 2021, I’ve been able to track down a plastic free mouthwash option. Georganics makes their plastic free mouthwash tablets from entirely natural and non-toxic ingredients. The Fluoride, Glycerin and SLS free formula helps to restore a healthy pH balance to your mouth, maintain good oral health and freshen your breath. Flavored with organic Spearmint oil or Orange oil (depending on which flavor you purchase), these eco-friendly tablets, that you add to water, are ideal for everyday use and travel. I adore their completely plastic free packaging! To use them, you simply dissolve a tablet in water and then swish for fresher breath.

Mouthwash Recipe Experiments

These are the three different easy homemade mouthwash recipes I tried. I thought I’d share all three in case you’d like to do some experimenting of your own and make them all!

Baking Soda Mouthwash: 1 cup distilled/purified water, 1 tsp baking soda, two drops of peppermint essential oil. The baking soda will eventually settle so you’ll need to shake it up a little before use.

Hydrogen Peroxide Mouthwash: 1 part hydrogen peroxide, 1 part distilled/purified water, and two drops of peppermint essential oil.

Apple Cider Vinegar Mouthwash: 1 cup distilled/purified water, 2 Tbsp. homemade ACV.

I chose the baking soda mouthwash to keep stored in my bathroom for regular use. I loved the saltiness of the baking soda mixed with the freshness of the peppermint oil. It also is the one of the three that is most similar in taste to conventional mouthwash. I also liked the ACV recipe, because it had a really mild flavor. However, I wasn’t a huge fan of the aftertaste of the ACV mouthwash. I didn’t dig the hydrogen peroxide mouthwash, but everybody’s taste buds are different so might be worth a try for you!

  1. I love this! Can’t wait to try it the baking soda recipe. Thank you!!!

    1. It’s so simple to make, we love it! Let me know how you like the recipe if you get a chance to try it out! 🙂

  2. Looking forward to trying these and testing them out. Will probably go with the baking soda recipe first. Thanks for sharing!

    1. Certainly! We love the baking soda recipe. It’s really refreshing!

  3. I need to try this, thanks for sharing! 🙂 I’d love to use less packaging and waste in our bathroom.

    1. Certainly! We’ve slowly been eliminating plastic and packaging in our house and I feel like the bathroom is such a good place to start! We use this homemade mouthwash, as well as compostable toothbrushes, zero waste tooth paste, soap bars, shampoo bars, and safety razors! 🙂

  4. Hi, could you please answer a question for me? In all the recipes it calls for distilled/purified water. Would just regular tap water work?

    1. Hi Andrea! The recipes call for distilled/purified water for a couple of reasons. Tap water often contains trace amounts of chemicals and metals like chlorine so using distilled water means you’ll have a mouthwash devoid of chemicals. Also, everyone’s tap water tastes a little different so using distilled water in the recipes is a way to make sure the recipes are always consistent and taste the same no matter where you make them!

  5. What is the shelf life for the baking soda mouthwash?

  6. It ultimately boils down to what you need to use an oral rinsing solution for. Saltwater rinse is often recommended for soothing oral pain as mentioned above and it is excellent at killing bacteria because the said bacteria cannot live in salt.
