When the next bottling day comes up, I load all my clean (but not sanitized) bottles into my dishwasher. No detergent or anything, just precleaned bottles. Then I'll run a full heavy cycle. Heated rinse, heated dry. The bottles come out clean and dry, and HOT. That water gets close to boiling, so I'm not worried about anything surviving.
I used to do two cycles to be safe, but if the bottles are already clean I found it to be overkill. I've done about 10 batches this way so far and had no problems whatsoever. I also save money on star San.
You probably spend more on the electricity to run the dishwasher than you would spend on StarSan.
I found the vinator to be the best time saver ever. The night before I bottle I wash the bottles in the dishwasher then right before I bottle I sanitize em and use the dishwasher to hold them afterwards.
