Fibers in garments each react differently when treated with stain removal products and during laundering. Always read hang tags and labels before attempting to remove a stain.
Silk
Silk fibers are made of protein and will dissolve in chlorine bleach. Even dilute solutions of chlorine bleach will cause permanent yellowing, color loss and weakening of silk. All stain removal products should be tested in an inconspicuous spot. Professional cleaning is usually recommended for most silk garments.
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.
