Rub the leather gently with a soft shoe brush to take off any dust, dirt or grime that may be on the furniture.
Purchase a leather repair kit and fill the cracks with a specially formulated leather filler that is the same color as your furniture. Sand it down to a smooth finish with 240-grit sandpaper when it dries.
Rub in the scratched leather solution that comes with the repair kit. Let it dry overnight and do not touch the furniture until it dries completely.
Apply a leather furniture protector to the newly restored cracks. Leather protector oils the surface and keeps it from becoming dry and cracking. Reapply this oil every six months.
