I think it needs to be stressed that you NEVER directly combine bleach with vinegar. Always add them individually to the water. Also, sanitizing with bleach needs the vinegar to be effective. Lastly, don't use Clorox brand bleach, buy the cheapest bleach you can find as it works the best.

pH strips are the best method to tell when it's time to dump starsan.
For great info on sanitizers I strongly suggest listening to these Basic Brewing Radio podcasts. I listened to them the other day and learned a lot.
