either way, unless something is serialized in a sterile environment, it's not going to stay sterile anyway. My kitchen table where I mix isn't sterile.... and neither are the bottles with the concentrates in, so as soon as I start mixing something it's not sterile.
so I think we are going off track a bit here ........ as long as the bottles are 'clean' that's all I care about.

... but I know nothing
But the manufacturers bottles most likely come from similar sources as our smaller bottles. So why would we assume theirs are clean and ours are manky?
That's why i clean em....just to be sure like....I also clean salad leaves from Tesco's...that are supposed to be clean....whatever your comfortable with...either way.
I think my 'fear' comes from buying attys and them arriving covered in machine oil..... I don't want anything like that in my bottles and it effecting the taste.
