Craft Meister Alkaline Brewery Wash gets the results of professional caustic without burning your skin or hands. Dissolving rapidly in both hot and cold water, Alkaline Brewery Wash works quickly to break down heavy soils and removes even the most stubborn bottle labels. Great for an overnight soak, but not suggested for use on aluminum.,The biggest difference between this and an Oxygen based cleaner, is the length of time the cleaner will work. With oxygen based cleaners, as soon as that active oxygen degrades, you are just soaking in dirty water again. The Alkaline however, will continue to work long after Oxygen based cleaners stop. If you normally leave a dirty carboy or keg overnight with PBW or OxiClean, the Alkaline Brewery Wash will do that job better.,,,Alkaline wash cleans brew kettles, corny kegs, fermenters, fittings, tubing and bottles,,,Use on glass, plastic and stainless steel,,,Works in hot or cold water and rinses freely,,,No chalky build-up,Directions:,Fermenters, Fittings, Bottles and Tubing: use 1 oz (2 scoops) per gallon of water.
