Closets often develop unpleasant musty odors that can affect your clothes and the entire room. Cleaning them can be challenging without a complete overhaul, which usually involves extensive washing and airing out. Finding a straightforward and efficient way to deodorize your closet can help maintain a fresh scent without the hassle of deep cleaning.

Baking soda is renowned for its cleaning capabilities, and it stands out as a powerful solution for musty smells. Keeping baking soda in your closet is a common practice among those who enjoy a pleasant fragrance in their spaces. By incorporating this simple baking soda method into your routine, you can ensure your closet smells fresh all year long.

This easy technique can turn a musty closet into a refreshing haven. Here's how to do it:

  • Begin with half a cup to a full cup of baking soda, adjusting the amount based on your closet size and odor intensity.
  • Add a few drops of essential oils to the baking soda for a lovely scent. Oils like tea tree, lavender, or eucalyptus not only enhance odor absorption but also leave a lasting fragrance.
  • Place several open containers filled with baking soda on different shelves or corners of your closet. You can also use fabric sachets or old socks filled with baking soda, as suggested by cleaning expert Karina Toner.
  • Ensure the containers are in a secure spot to prevent spills. You might use double-sided tape to hold them in place.
  • If a hamper in your closet is causing the smell, sprinkle baking soda at the bottom daily or as necessary. Any baking soda left on clothes will also help deodorize them during washing.
  • Allow the baking soda to sit in the closet for a night or a few days to absorb lingering odors.
  • Replace the baking soda every month or so, or when you notice its effectiveness decreasing.

  • Baking soda neutralizes pH levels, effectively addressing both acidic and basic odor molecules, as explained by Michael Golubev, founder of Mold Busters. This not only eliminates existing odors but prevents new ones from forming.
  • Contrary to many commercial air fresheners, baking soda is safe, non-toxic, and eco-friendly.
  • Its versatility makes it an essential part of your cleaning supplies—use it for shoes, drawers, and laundry baskets, too.
  • Baking soda helps reduce humidity, which often leads to musty odors in closets due to poor airflow and damp clothing.
  • It's also an affordable choice that can be purchased in bulk, making it a budget-friendly option for odor management.

In addition to baking soda, regularly opening your closet doors can promote airflow and help prevent odors from building up. For closets that are susceptible to moisture, consider using activated charcoal for even better odor absorption.
