If you use essential oils with any frequency, you’ve likely run into this predicament. No matter how much you shake and tap, the last few drops just won’t come out of the bottle. Here is a clever, frugal trick for using up the last few drops from your (almost) empty essential oil bottle. Make infused Epsom salt! (Or infused baking soda!)

For hundreds of years, folks have soaked in Epsom salt baths to ease aches, pains, and sore muscles. Epsom salt, or magnesium sulfate, is a natural mineral salt which breaks down into magnesium and sulfate in warm water, where it can then be absorbed through the skin. While it seems more hard science is needed to “prove” its effectiveness, generations of people claim relief from a number of ailments from headaches to insomnia to arthritis. And certainly, a warm bath is stress relieving (with or without Epsom salt.)

Infused Epsom salt takes your soak to the next level. If you’ve come to the end of the bottle of essential oil, it is no doubt a favorite scent of yours. All the aromatherapy benefits you crave + a relaxing warm bath? What’s not to love?!

How to Use (Nearly) Empty Essential Oil Bottles to Infuse Epsom Salt

First, collect a few nearly empty essential oil bottles and pop off the dropper tops. Fill a glass jar or container (preferably glass, but plastic will work, too) with a cup or so of Epsom salt. Next, place the bottles, lids, and plastic dropper pieces into the jar, secure the lid, and gently shake to cover and fill the bottles. Allow them to sit for a day or two to give the salt time to absorb all that oily goodness. Remove the bottles and parts from the salt and store the infused Epsom salt in an airtight container until ready to use.

You can now wash the bottles, lids, and droppers in warm soapy water. (A straw brush may help to really get them clean.) Reuse and repurpose these handy little bottles! Store your own custom oil blend, use them for travel containers, or check out some of these other ingenious ideas for reusing these adorable brown bottles.

How to Make an Infused Epsom Salt Bath

Run a very warm bath and pour in 1-2 cups of Epsom salt, swishing it around to dissolve. Soak for 15-20 minutes. Breathe deep. Relax.

Most people are able to enjoy an infused Epsom salt soak, but if you have any concerns about whether this may be right for you, always check with your healthcare provider! And, as always, make sure the essential oil you are using is appropriate for use on your skin, especially if you’re nursing or pregnant.

No Epsom Salt? No Problem! Make Infused Baking Soda

If baths aren’t your thing, this hack for using every last drop from your nearly empty essential oil bottles will also work with baking soda! Infused baking soda makes a great air freshener when placed in a loosely covered (or uncovered) jar. Or use your aromatic cleaning powerhouse as a gentle scrub. This works especially well with lemon or tea tree infused baking soda. Check out this post for more idea about how to clean with baking soda.
