I love star-san. Mix it up in distilled water and spray down everything involved in the process. It's cheap, effective, and for sanitizing carboys, it is the best. As the foam is displaced and comes out the top, even the foam is anti-bacterial. And it doesn't small bad, isn't bad for your skin, it's really excellent.
The one time I don't use Star-san is when bottling. Then a jet rinse with KMeta, since a tiny bit extra won't hurt anything.
