...per the title, apparently I left a 3 liter camelbak about half full, for over a year. I didn't see anything growing inside the bladder and I have cleaned it with vinegar water. I turned the thing inside out and rinsed it well. What else should I do? I'm not afraid of bleach but would rather not muck about with it. What about dish soap?
Any ideas are welcome.
/note: it currently passes the sniff test and the visual test too.
