I picked up a couple of glass carboys a while back on craigslist. One of them, I later realized, had some stains on the inside. I tried cleaning with a hot oxyclean soak, then with starsan, both to no avail. I'm now soaking with distilled white vinegar but I think these stains, or deposits, or whatever they might be, are permanent. I hate to throw the carboy away, but I don't want to introduce mystery nasties, chemical or otherwise, into my beer. So I'm here for the consensus. Does anyone have similar experiences, horror stories, or reassurance?
