It's not that difficult to use. Be gentle and have a little common sense and you'll be fine. Regarding your pH comment: I'm a scientist, and pH usually refers to how basic or acid a solution is, therefore an actual leather item (shoe, for example) would not have a designated pH. Atleast, there would be no way to measure it. Now, applying products to the shoe that are a neutral pH (around 7.0) would make sense for the care of the shoe.
