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

To effectively use baking soda or baking powder to eliminate unwanted smells in your home, simply place an open container of either substance in the area where the odor is present. The baking soda or baking powder will help absorb and neutralize the smell over time. You can also sprinkle baking soda on carpets, upholstery, or other surfaces, let it sit for a few hours, and then vacuum it up to remove odors.
