100% correct. Because what keeps the leather supple is some sort of animal fat or related product - whether lanolin, neatsfoot oil, or the sweat off my grubby fingers.

And petroleum products dissolve animal fats, such as lanolin and neatsfoot oil, and whatever natural fatty elements were in the leather before - and are not good for my skin either!
