Odor removal refers to the process of eliminating unpleasant smells from various environments, such as homes, cars, or commercial spaces. Common sources of odors include pets, smoke, food, and mold. Effective methods for odor removal can include cleaning, ventilation, and the use of specialized products like air purifiers or odor-neutralizing sprays. Techniques for odor removal vary based on the source and severity of the smell. For instance, baking soda can absorb odors in refrigerators, while activated charcoal is effective in absorbing moisture and smells in enclosed spaces. Regular cleaning and maintenance can also help prevent odors from developing.
