leave an inch or so of water in the bottom for an hour or overnight, then shake, dump, and let drip dry.
In general, I'm always trying to use water responsibly:
After pouring bottles: Rinse, rinse/shake, rinse, drip-dry. With visible film remaining, soak w/ 1/2" of hot tap water overnight, and/or bottle brush - always drip-dry.
Extra dirty bottles and virgin (labeled) bottles get 1-2 hrs in Oxy. (in bulk: 25+, to re-use the 3-5 gal of water a few times). Then quick hot water sink rinse, then full immersion in warm rinse water. For this I reuse a narrow/tall Brita pitcher capable of immersing one 12oz/22oz bottle (let bottle fill up to sink, then soak for a minute so films/soap/oxy/etc can float up-and-out, then pour it back into the Brita). Finally an outer, then inner rinse/shake with hot tap water, visual inspection (backlit), and drip-dry. Sanitizer/spray inner + sanitizer neck-dip + 2 min drip on bottling day.
I'll rinse, rinse/shake, drip-
dry and store somewhat open (dry, upright, no lid or unsealed lid on bin) any bottles waiting for the Oxy-bath until I have enough to make efficient use of a bucket of water.
