Burn markings should never be rubbed or scrubbed at. Dabbing methods also will rarely remove soot on burnt carpet. Carefully push the unaffected fibers away from the burned section. The burn will often be on the surface or top portion of each carpet fiber. In this case, use craft or cosmetic scissors to snip the burnt section of each carpet fiber away. Use a garment brush to overlap unaffected fibers around the snipped pieces.
