Depending on the bottles, too. I like giving new bottles and recycled bottles a wash in generic unscented oxyclean first. I fill my sink with oxyclean water and soak the bottles and scrub them out with a bottle brush if needed. This will clean out any dust or funk or dead yeast debris from the bottles. From there, they get a rinse in clean water on the other side of the sink and they sit until brew day. On brew day, I scrub out one side of my metal kitchen sink and hose it down with bleach water, then rinse it out well and add idophor. I dunk the bottles in idophor, shake once, drain them and rest the bottle on an idophor sanitized bottle tree. I do this right before I bottle my beers. Drying isn't necessary and they stay sanitary until needed. Caps also get a soak in idophor water.
Typically, i'll fill half a case of beer at a time, then stop, cap them and return to bottling the rest. It's just what I like to do.
