What fabrics must be dry cleaned, and what is the main advantage?
Unless the label indicates otherwise, the main fabrics that are recommended for “dry clean” only are: linen, rayon, silk, and wool. These fabrics may lose their shape, color, size or quality when washed in water. Dry cleaning uses a liquid solvent to clean while protecting the delicate structure of these items. If a tag on your favorite piece of clothing says “Dry Clean Only,” it’s best to leave it to the experts.
