@DWFII, much agreed. Hostility is completely unnecessary. However, if you are going to discuss scientific tenets, I think accuracy in language is extremely important.
@traverscao, on your points: I don't think all manufacturers or all designers wanted to be very careful about the cleaning products they use, create, or recommend. There are many that still sell saddle soap as a cleaner, even if it is a terrible product. I also understand what you meant by "buffer zone", but that term is simply not used to refer to what you're referring it to and could be confusing to people reading this thread. I certainly had no idea what you were referring to.
On the subject, I'd actually agree with @patrickBOOTH, that you want a product that is slightly acidic, not a neutral product. Even pH balanced (neutral) soaps are drying to the skin. They are also probably not the best choice for leather, but they are certainly better than something alkaline.
Thanks for getting it, Monotovs. Feel free to converse as per needed.
