I just picked up my new 09 GMC Sierra SLT with leather seats and while reading the thick owners manual I came across the "Care" section and in it, it said not to use any type of leather cleaners/conditioners as they can contain harmful ingredients that can damage/stain the factory leather surfaces?

It said to used a mild soap/water mix and clean terry cloths or something similar?
I was quite surprised at this as I figured it would state the opposite?
I also take it, not all car interior leather is the same? Are some manu's seats/leather better quality than others? Should I just do as the book says and only clean it peridocially and never condition it afterwards?
I plan on keeping this truck for many years to come so I want it to last. Thanks..........Irv
