There are half a dozen different options on the market. The Chemical Guys variation of leather cleaner and conditioner is my first one to try The cleaner seems to work well. I'm not sure what is in it, as the ingredients are not listed. It did seem to clean up the soot from the cigarettes that were smoked in this car once upon a time. Got some grime and general dirt of the back seat from my little one climbing in and out. I think it does a decent job.
The conditioner certainly does soften the leather. It leaves a visible shine but, is not overly shiny. It leaves a nice polish on the leather if you will. The down side for me is that this stuff is leather scented. It does a good job of smelling like leather but, it is much too strong for my sensitive nose. If I do all the seats in the car, I have to leave the windows open to air out the smell. They do have an unscented version as well. Other than that, I have nothing to complain about for this product. I think it works well but, my knowledge of other leather conditioners is not good. I'd like to try another product once I use up what I have of this. I'll add a comparison of that later down the road.
I've got a few photos of before and after. I think it is hard to tell the difference personally. It is one of those, have to be there in person kind of things. This is not working any miracles on the old leather by any means but, it certainly does soften them and, leaves a nice sheen.

|After - there is that bit of shine|
