Wool and Cashmere
Wool and cashmere fibers are made of protein and will dissolve in chlorine bleach. Even dilute solutions of chlorine bleach will cause permanent yellowing, color loss, stiffening and weakening of wool. All stain removal products should be tested in an inconspicuous spot. Professional cleaning is often recommended for wool garments. Home dry cleaning kits can be used by following all product instructions.
Extremely high temperatures when ironing can scorch silk, wool and other hair fibers. The scorching or yellowing occurs as the fibers begin to burn. Burned fibers cannot be revived.
