Question: How often should upholstered office chairs be cleaned? Where in the IICRC reference material would I find this information?

Unknown to most commercial end users is the fact that commercial upholstery, unlike residential, experiences a lot more daily soiling and wear and tear. Commercial upholstery should be cleaned at least annually by a professional cleaning service that knows how to remove maximum soil, perhaps semi-annually in heavy use situations. The increased use life of the upholstery and the savings in productivity will pay for the cost of cleaning.
