Furnishings are upholstered with a variety of fabrics and paddings. It's important for a service professional to know what they're made of when it's time for cleaning.
Some fabrics cannot be cleaned with water and must be dry cleaned. Leather requires its own special treatment. Some silks can only be vacuumed.
Most reputable upholstery cleaners will want to come to your home to inspect your furnishings and give you a free estimate rather than guess how or if they can clean them for you.
