What Parts of Your Home Hold Onto Smells?

Parts of your home that could be neglected and may smell without you realizing it include your walls (yes, you can clean your walls!), your carpet padding, inside your air conditioning ducts, and behind and around kitchen appliances and furniture. In addition, your couch or other upholstered furniture might be holding on to lingering odors. A professional carpet cleaning company will usually also be able to clean your upholstered furniture, and may even be able to add a protective coating that will repel liquids and smells.
