Overview
- Place two to five tablespoons in a small open dish or jar and set it under the bed, in closets, kitchens or bathrooms.
- In bathrooms or very humid rooms, replace every 10–15 days or weekly if odors persist, while bedrooms can range from one to two weeks to about 30 days depending on conditions.
- The compound is slightly hygroscopic and neutralizes odor‑causing molecules rather than masking smells or releasing fragrances.
- Some outlets suggest mixing baking soda with uncooked rice or adding a few drops of essential oil for scent, though these are household tips with limited corroboration.
- Reporters caution that this method complements ventilation and cleaning and does not resolve structural damp or mold that may require a dehumidifier or professional remediation.
