Scorch upon cotton and linen sometimes can be removed, if the fibers are not actually burned. Wool and silk are disintegrated at a lower temperature than cotton and linen and cannot be restored to their original condition after being scorched.
For removing slight scorch stains from cotton and linen, use one of the following agents:
1. Soap and water (ordinary laundering). This is sufficient to remove very slight stains.
2. Water and sunlight. Wet the spot with water, or soap and water, and expose to the sun for a day, or longer, if necessary. The scorch disappears much more slowly if the material is not moistened before exposure.
3. Bread crust. Very slight scorch on the surface of materials which are not especially delicate sometimes can be rubbed away with a bread crust.
