Although a 3 in one product or 2 in one product works, if you want the best results, get a leather cleaner and a separate conditioner. I prefer meguiars as I buy their products by the gallon, but most work. Something to note, you do NOT want your leather to be shiny. Shiny=bad, it will dry out and crack. Some conditioners contain silicones that make leather shiny, and those are terrible for leather, silicones cause the leather to dry out faster and crack. The cleaner will take out any body oils and dirt that will make the leather shiny, the conditioner will rehydrate the leather after cleaning it. A mistake many people make is applying too much conditioner. A little bit goes a long way.
