Some scorch marks from an iron are removable using hydrogen peroxide and ammonia. Once the stain is saturated, keep it wet for up to an hour. Rinse away the peroxide solution, and launder using oxygen bleach. The overall process requires approximately three hours. Heavy scorch marks or shiny marks due to an iron are impossible to remove. Even if you are successful in removing the stain, the excess heat weakens the fibers of the garment, so it wears more quickly than unburned materials regardless of the stain removal method.Continue Reading
Hydrogen peroxide bleaches some dark colors. Test in an inconspicuous spot to see if this approach is appropriate. If the hydrogen peroxide causes fading, attempt to remove the stain using another approach.
Apply the hydrogen peroxide to the stain using an eyedropper. After wetting the stain, apply two drops of household ammonia. Continue to add more hydrogen peroxide and ammonia to keep the fabric wet for an hour or until the stain fades. Cover the wet area with plastic wrap to reduce evaporation. Rinse away the solutions using clear water.
Wash the affected garment using laundry detergent and oxygen bleach. Dry, and check the mark.
