I'm not a expert in any way on plastics but that looks like a stress fracture to me.
It's hard to imagine soaking in a cleaning agent could cause that kind of crack. My first thought when I saw the picture was that they must have had a problem in the mold that left a section weaker than normal or the part was abused in some way (not throwing stones, just thinking about it like a tech).
For their customers sake I hope there contract manufacturer figured out what was causing this to happen and fixed the build process. Not cool to blame your customers though.
That's what I was thinking too Paul. I just can't see how PBW would cause or accelerate a fracture like the one in the photo. Looks like a stress fracture or a manufacturing flaw to me.
