A safe alkaline cleaner for everything in your brewing setup!
PBW (Powdered Brewery Wash) is a favorite of small home breweries because it out-performs caustic chemicals without scrubbing. Just put your kettle, bottles, carboy, etc. in for a good long soak. It will not corrode soft metals.
Please be careful when you use PBW in enclosed equipment. When you mix hot water and PBW in an air or water-tight space, it will create pressure.
