I grab bottles out of recycling bins. So they're filthy. Sometimes I rinse them, most of the time I don't. I dump them in a big plastic bin. 2 scoops of oxyclean and hose water to the top. Let soak for 24 hours. After that I rinse and sanitize with a couple squirts of star san which I have in a spray bottle. Let drain on the bottle tree.
Never once had an infection. Works like a charm. Been doing this for years now.
