I havent done a lot with leather in the past, but I have used that product before. It is a fairly thick cream. To me, it seems to be more geared towards protecting than cleaning. It could be something that you would use once a month. But, if you needed to do some serious work to leather, this wouldnt cut it.
In my opinion... id rater have a dedicated cleaning solution of some intensity, and then another solution that is only geared towards protection. That way you would only use how much of each thing you really need.
