There is a lot of truth to that. Unfortunately, it's sometimes the toughest question to answer, even by those who have been in the industry for many decades. There is such a shroud of secrecy around ingredients in shoe care products that it often comes down to anecdotal evidence and personal experience for what works best. It's frustrating to find the right answer. Also, a lot of it is about balance. One person may sparingly use a product that isn't as good as someone else who uses too much of a high quality product and end up with better results simply because they aren't over doing it. There are way to many variables to have one simple answer.
