Rub the scuff marks with a pencil eraser. Use a large hand-held pink eraser instead of the end of a pencil for larger scuffs. Erase the scuff marks gently until they disappear, then brush away the residual eraser dust. Use this method for light scuff marks.
Squeeze some non-gel, old-fashioned white toothpaste onto a soft cleaning cloth and rub slightly darkeer scuffs out. Use a circular motion without pressing too hard to take advantage of the naturally mild abrasive in the toothpaste. Rub the scuff away, then rub the remainder of the toothpaste away with a clean cloth. Use a bit of water if needed.
Clean more stubborn scuffs with a foam cleaning eraser designed to get rid of scratches and scuffs on surfaces. Wet the cleaning sponge and rub the scuff marks until they disappear.
