Nothing in the above posts to fault. All procedures will work!
I can advise with 40 years of brewing (experienced but not a true expert) I have never had a bottle infection.
Two basic rules:
1) Your first use bottles need special attention, God know where you got them: soak, sanitise, inspect, dry & cover.
I have necessarily used at times really grotty bottles. To get the hardened bottom sediment out I use a half handful of course sand or fine gravel, add cold water, shake the shit out of the bottle & repeat until no more sediment is seen, then sanitise normally. It's tedious but there were times when that was my only option.
2) For repeat use bottles: It's crucial that the empty bottles are washed asap, no longer than overnight. Just get into the habit. Washing normally is a quick rinse & shake with hot tap-water, At least twice, normally 3 times, about 300 ml of hot tap-water per rinse, Drain on a bottle tree until dead dry, inspect & cover.
These days when I use bottles some of which are 10 years+ old, I just pick from my collection, without any further effort to clean; but you can only do this if you have used screw down tops, They are the means by which you effectively "cover". Tried other ways & once ended up with every bottle half full of ants making a home/city. Never again!
Note the simplicity of this routine which works. Back when I started, it was with the help of a couple of old time brewers (washing machine bowls for fermentors) covered with clean towels. They also never had bottle infections (or ants!) & used the above procedure. So it's well proven. I see now an almost fetishist attitude to bottle cleansing. Its just not necessary!
