No I don't, I rely on about 20 minutes of contact. Bottles get washed with the bottle washer, which leaves the bottles wet and with some foam in them. They then get hung upside down on my bottle tree (which has also been starsanned) while I wash all my other bottles and get the rest of my gear ready.
Contact doesn't mean submerged in solution, it just means a wet surface.
I've been bottling like this since I started brewing and haven't had an infection yet. Also means I don't waste copious amounts water and starsan. It is fast easy and effective.
