Homemade Natural Mouthwash Recipe

So I found this gorgeous decanter at an antique shop a couple of weeks ago. My mom had this great idea to fill it with homemade natural 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 natural 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.

Peppermint Oil, Homemade ACV, & Hydrogen Peroxide

Mouthwash Recipe Experiments

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.

And The Winner Is!

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!

  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?
