A deodorizer is a product designed to eliminate or mask unpleasant odors in various environments. It works by neutralizing odor-causing substances or releasing pleasant fragrances. Deodorizers come in many forms, including sprays, gels, and solid blocks, and are commonly used in homes, cars, and public spaces. These products can be made from natural ingredients, such as essential oils, or synthetic compounds. Some deodorizers target specific odors, like those from pets or cooking, while others provide a general fresh scent. Popular brands include Febreze and Glade, which offer a range of options for different needs.
