IICRC S300 provides a specific set of practical standards for all methods of dry and wet upholstery cleaning. It does not attempt to teach comprehensive upholstery cleaning procedures; rather, it provides the foundational principles for proper cleaning practice. There are numerous programs available in the industry to teach the specific details of upholstery cleaning.IICRC S300 is presented using a two-part format: the Standard itself, and a supplementary "Reference Guide." The procedural Standard is featured in the first section of S300. This Standard is supported by the Reference Guide in the second section. The intent is to use the information outlined in the Reference Guide as a tool to better understand and apply the Standard itself. However, the Reference Guide is not considered a part of the Standard.IICRC S300 is an essential document for all serious on-location cleaners to ensure compliance with state-of-the-art procedures and to limit liability for their company.
