Odors can be caused by pets, mold
, fungus, mildew, cigarettes, and cooking. An odor removal service should be called in to remove odors. Odor removal service experts are trained in using specialized chemicals for this purpose. You can't eliminate odors by shampooing, and spraying a deodorizer. Many odors are caused by micro-organisms such as bacteria, mold, and mildew. Not only does shampooing not eradicate these odors, it spreads them over a much wider area! An odor removal service will kill odor-causing organisms with specialized chemicals, ozone machines, and sometimes fogging.
