After spending forty years of my life as a horseman I have spent countless hours refurbishing leather saddles, riding boots and harness. I have also owned many cars with leather upholstery. I have found that it's a three step process. I first use saddle soap to get the dirt out of the leather. Secondly I would apply the right color of Kiwi shoe polish. Black for black, brown for brown etc.. Apply then buff of with a soft towel or fibre cloth. I then seal it with mink oil, neetsfoot oil or Belivior. Let it cure for 24-48 hours the buff again with clean dry cloth. Hope this works for you and GL.
