Specifically, what do most of use use for leather care? I just bought a reealy nice couch that I'm told will need treatments every six motnhs or so. i held off buying the store fed product for fear it might be a bit overpriced. They wanted to sell me a cleaning kit for $40 which I think included a 12 or 16 oz container of leather cleaner. How often do you all treat your couch? Is the couch "smelly" or somehow less "leather smelling like" after the treatment? The last thing I want to do is stink up my new couch. Michael.
