Wipe any dust or debris off the scuffed area of the sofa. You need a clean surface for applying the shoe polish.
Fold the second cloth and dip the corner into the wax shoe polish. Begin with only a small drop of polish, no bigger than a dime. Get more polish when the cloth feels dry. The polish must match the color of the sofa.
Rub the wax shoe polish into the scuff mark. Gently rub the scuff with the cloth to work the polish into the porous surface of the scratch. Allow the color to soak into the scuff and then give it time to dry completely.
Mist a light coat of Murphy's Oil Soap spray onto the surface of the leather. Wipe the spray off in a circular motion. If the leather has an obvious grain, wipe in the direction of the grain instead of using a circular motion.
