I use Starsan, Iodophor and heat.
Starsan because it last for at least a week and doesn't stain. I don't mind the bubbles, but I don't like using it on carboy bungs because they simply pop out of the carboy.
Iodophor because it works great for the bungs, and is a bit cheaper than Starsan, but it doesn't last for more than a day, and stains. I nust admit, I do like emptying it in the sink after SHMBO has cleaned it, and pointing out the deep stains.
Heat for mason jars and water that are going to be used for yeast washing.
