As I have no knowledge of Paul's methods, I don't intend posting conflicting views, or opinions, other than to comment that I have NEVER " followed the book " in anything I've done in life, always feeling there might be better, methods, tools, products, etc, but with leather, caution is paramount.
I've been fortunate, or maybe just lucky, in never ruining a client's furniture, but I have come across many leather suites, which had been treated incorrectly and had the potential, to cause me a serious problem.
The most important thing about cleaning leather, is to be as certain as you can be, that you can clean it safely and without compromising your good name.
As there are only so many ways of " cracking an egg " I suspect we have come to much the same conclusions, but using different products.
Not surprisingly, the training providers are avoiding involvement in this thread, but they must be staining at the leash, desperate to post warnings of potential disaster.
I rarely use brushes myself, but use them occasionally.
Hope the day goes well and leads to greater cooperation in the future. It's good to talk !
