You've looked at all the recipes you could find and are still confused, so I conclude you're not a scientist. IOW, like me, you're not particularly well qualified to DIY in this area.
Why not buy a product developed and tested by people who understand what they're doing?
In addition to the products mentioned above, AIVS makes a product called One-Step. It works pretty well. Not as well as their four-step process of course, but IME at least as well as the other products mentioned (all of which I've tried).
I still prefer a final rinse with AIVS's very pure water because cleaning without rinsing doesn't work for my brain or ears, but YMMV of course.
