Scorch marks occur when your iron is too hot for your fabric, or when you leave the iron in one place on the fabric too long. If the scorch is not too bad, there are a couple of things you can do to try to get it out. Light scorch marks can be treated with 1 part water and 1 part hydrogen peroxide dabbed gently on the mark. Also you can try a borax solution (1/4 cup borax to 1 quart of water) on the scorch. And if the fabric permits, it can be soaked in a bleach solution. Be sure to rinse throughly and wash as usual after treatments. On the down side, if the scorch is heave and dark, there may be nothing you can do to remove it. You may, however, be able to "decorate" over it, depending on where it is on the garment. You may be able to add a pocket or add an embroidery decoration over the scorch.
