Leather Care..what am I doing wrong?

I used the Leatherique 2 bottle kit exactly as described. The rejuvinator oil that was supposed to "lift away the dirt". then the conditioner. I was not overwhelmed with the results, either by the cleaning process, or by the supposed suppleness. I then repeated two additional times, used a soft bristle brush assuming that would make a difference. left the car indirectly in sun with windows closed to heat up the process. I am still not thrilled. Am I better off with a cream or different product? ...am I doing something wrong? This is a 1997 S420 with 72,000 miles.
