OneStep got me at first, too. It "says" it's a sanitizer as well as a cleaner. I call bull****. It's expensive up front, but like COLO said, buy a small bottle of Star-San. Mix a very small amount with a quart of water and put it in a good quality spray bottle. Spray the mixture on frickin' everything which comes within 30' of the kettle and bucket! Make sure that you're sanitizing the insides of tubing, as well as racking canes, auto-siphons, and the bottling bucket valve.
