When exposed to solutions containing alcohol, some dyes bleed or change color. Hair sprays, deodorants and perfumes must be allowed to dry before dressing. Remove spills (blot, don’t rub) from beverages as soon as possible. Some dyes especially blues and greens on silk, are sensitive to alkalis. Many facial soaps, shampoos, detergents, and even toothpastes alkaline is enough to cause color loss or change. Many times, these changes will not show up until after the dry cleaning process is complete. Many bright colors used on these fabrics can fade from exposure to sunlight and artificial light. Store garments in closets away from any lights or windows.
