Dampen a lint-free cloth with leather cleaner and conditioner. Alternatively, mix 2 parts neat's-foot oil with 1 part white vinegar in a bucket and use this homemade leather cleaner instead of commercial cleaners.
Hold one end of the lint-free cloth with one hand and grasp the other end of the cloth with your other hand. Start at the top of the leather and press the middle of the lint-free cloth against the leather. Begin moving the cloth in a vigorous back-and-forth motion across the leather.
Continue moving the cloth vigorously across the leather while slowly moving down. Add more cleaner and conditioner to the cloth when it becomes dry. Continue buffing until you have moved across the entire surface leather item.
Dampen a clean, lint-free cloth with olive oil. Buff the scratches off the leather in a circular motion. Let the leather dry completely.
