Preventing fingerprints from appearing on plastic or metal components is extremely difficult. The grease that is secreted from the eccrine glands that are present in the epidermal ridges of finger tips simply smears when you try to clean it. A detergent of some sort is needed to lift the grease.
But what if you could wipe off the fingerprint with just a soft cloth and no detergent or cleaner? Then there would be a financial, time and environmental benefit.
