I use all three of the Craftmeister products, but I don't overnight soak anymore. I like the convenience of tossing a tablet in my homemade carboy cleaner (pump in a bucket with a copper pipe with holes in it to spray the surfaces and QDC lines for hooking up kegs) - a neighbor made it for me, but I will mix up a couple gallons at about 1/2 strength for use, also. I tend to rinse things out well when emptied and pile them up and then do an assembly line of cleaning multiple carboys, kegs and the like on one occasion, so the cleaner goes pretty far.
I like Craftmeister because it works really well cold or hot and unlike PBW, it doesn't become a hard rock in the container over time.
