Every time you sit on or touch your couch or other upholstered furniture, the fibers come in contact with body oils, sweat, odors, dirt and particles from humans and pets which then gets mixed in with dust and stays on the fibers. This combination will make upholstered furniture dirty and can cause discoloration.
Regular upholstery cleaning will prolong the lifetime of your furniture, help retain the original color, keep your air cleaner, and make your upholstery clean and sanitary.
