Best way to clean bottles

Steps (assuming you have rinsed out the inside already):

1. Soak for 1 hour in hot water (washing machine works well for this)
2. Use a knife to scrape off as much label as possible
3. Use a copper pot-scrubber to get off the rest of the label and glue
4. Heat* in a 400deg oven for 1 hour to sterilize or use one-step to sanitize

* If you try to heat sterilize before removing all the label glue you will get an awful stink, for sure.
