How can I effectively use baking soda or baking powder to eliminate odors in my home?

To effectively use baking soda or baking powder to eliminate odors in your home, you can place an open container of either substance in areas where odors are present. The baking soda or baking powder will help absorb and neutralize the odors over time. You can also sprinkle baking soda on carpets, upholstery, or other surfaces, let it sit for a while, and then vacuum it up to remove odors.
