It is important to understand the fiber and construction type you are dealing with in order to prescribe the proper cleaning method, and to avoid problems for you and your customer.
The most important part of fiber identification for upholstery is to determine if you are cleaning “natural” or “synthetic” fibers. As a general rule, natural fibers have to be cleaned with a lot more care. Upholstery fabrics often come in blends. When this occurs, be sure to clean the fabric as if it were completely made from the most sensitive fiber (usually natural). The most practical way of identifying fibers is to use the Burn Test procedure.
