I speak from experience, but if you do not wish to believe it, by all means do not. I know what I will and will not do again with PBW and am comfortable with my current procedure.
a simple google search will turn up many people who have ended up with something that looks like what you see on page 8 here.
The text under the photo says 'likely caused by' a high concentration of pbw for 8 hours.
I'm not going to argue that pbw can cause a problem but those are weasel words. They need to prove it causes problems. Why not work with 5 star since better bottles and pbw are a staple in just about every homebrewers garage?
Again, I'm not arguing with you or better bottle. I just would like clear evidence and not maybe it was caused by misuse of a cleaning product.
