Try some toothpaste if it just minor scratches and go in the same direction as the "grain". Nylon scuff pads can do the job but getting the right level of abrasive is the trick so if you can find a spot to test the abrasive pad to get the right "scratch" level try to find the right pad. Try and apply even pressure so you have and even "scuff"...finger tips don't apply even pressure across the contact area so use a small piece of wood to spread the pressure evenly. It can be tricky and takes some finesse but with patience and elbow grease it can be done.
