I would not pull a bottle that had been in storage for XX months out and just sanatize it and expect to be good to go.
I know that when I put an empty bottle into storage for the next batch, I rince them a few times, maybe add a bit of dish soap if I remember, rince, and throw them into the storage case. There's no way they stay clean throughout that whole period. So much can go wrong....mold, mildew, even soap residue from not rinsing completely.
So, when I pull that bottle out to use it for the next batch, just spraying with a bit of sanatizer isn't going to cut it. Mold, mildew, and and residual soap scum are likely to nto be visable, and while a few sprays of sanitizer may neutralize these factors, it isn't going to eliminate them.
On bottling day, I fill up the sink with warm water and oxyclean. I flood each bottle, shake the crap out of them rince with tap water, do a quick spot check for any nasties at the bottom, then put them upside down to dry. Once I finish, I go in reverse order and either spray with starsan or make a new sinkfull of starsan solution and flood each one again, and again store upside down to drip dry.
Takes me about 30-45 min or so to clean and sanatize a batch of bottles.
