How do you remove scorch marks left by an iron on a carpet?
To remove light scorch stains from washable materials, sponge them promptly with cool water. Or soak them in cool water for 30 minutes, then work undiluted liquid laundry detergent into the stains and rinse. Light scorch stains on nonwashable materials can be removed by sponging the fabric with hydrogen peroxide (test first for colorfastness), then sponging with water. Scorch stains are almost impossible to remove from silk or wool. Brushing the spot on a thick wool carpet lightly with emery cloth or very fine sandpaper may improve its appearance, but the stain cannot be removed if the carpet fibers have been burned.
