After a period of time, the appearance of your upholstered furniture pieces may be dulled by an accumulation of soil which is not readily removed even by frequent vacuuming. When this occurs, it may become necessary to clean your upholstery by using appropriate cleaning products and equipment. This booklet is designed as a guide for the care of upholstered furniture.
