Let’s face it: If you have carpet in your home, chances are you’ve used carpet powders from the store, such as Arm & Hammer’s Carpet Odor Eliminator, which contains sodium bicarbonate (baking soda), hydrated silica, polyoxyethylene tallow, ethylmonium ethosulfate, and fragrances.
As someone who suspects Multiple Chemical Sensitivity (MCS), these ingredients are a hard pass for me in my home.
While MCS is not considered an “illness” by the American Medical Academy, it is a collection of noteworthy symptoms triggered by chemicals such as the 3,100 or so stock chemical ingredients used by the fragrance industry (1). MCS is a very real issue for many people (2). Some professionals refer to it as Sick Building Syndrome (3). MCS symptoms include:
- Burning eyes
- Breathing problems
- Cough
- Changes to heart rhythm
- Chest pain
- Confusion
- Congestion and other sinus trouble
- Diarrhea, bloating, and/or gas
- Digestive problems
- Dizziness
- Fatigue
- Headache
- Itching
- Memory problems
- Mood changes
- Muscle and joint pain
- Nausea
- Poor concentration
- Rash
- Sensitivity to light and noise
- Sleep issues
- Sneezing
- Sore throat
- Trouble concentrating
This is a long list of undesirable symptoms. Clearly, caution is warranted with the products we allow in our homes. So, what can we do to improve carpet odor?
That’s when an all-natural, toxin-free carpet powder comes into play. This DIY is a straightforward and inexpensive swap that anyone can do. You only need a shaker bottle, basic pantry staples, and optional essential oils for cleaning. I like eucalyptus globulus, lemon, and sweet orange because they’re safe for dogs, kids, pregnancy, and breastfeeding. Looking for more dog-friendly essential oils?

You may have noticed I didn’t specify using aluminum-free baking soda. Not to worry; all baking soda is free from aluminum (it’s baking powder that has aluminum). Now, let’s get to the odor-banishing recipe that’s guaranteed to freshen up your carpets.
EQUIPMENT
- 16-ounce shaker bottle (I used a vintage glass spice jar similar to these)
MATERIALS
- 1 – 2 cups baking soda (if using cornstarch or arrowroot powder, only use 1 cup)
- 1 cup cornstarch or arrowroot powder (optional, for moisture absorption)
- 20 – 40 drops of essential oils for cleaning (optional, for scent, cleansing, or both)
INSTRUCTIONS
- Fill the shaker bottle with baking soda and, if using, cornstarch or arrowroot powder.
- Add 20 – 40 drops of essential oils and shake well to incorporate.
- To use: Sprinkle generously on your carpet, let sit for 20 – 30 minutes (the longer, the better), and vacuum thoroughly.
NOTES
- Some online information claims that using baking soda with vacuum cleaners can void the warranty. I recommend checking your vacuum’s warranty information before making or using this DIY carpet powder recipe.
