Five Star Chemicals has been producing cleansers for commercial breweries for some time, and has now packaged their cleaning technology into home brewing sized packages. Their approach is twofold; the brewer first uses Powdered Brewery Cleaner to remove deposits from equipment, and then uses Star San, a professional grade soaking sanitizer, to sanitize the cleaned equipment. Both PBW and Star San are safe for limited contact use with stainless steel, plastic, copper, brass, and ceramics, and are safe for septic systems.
This 50 lb. pail of PBW will make up to 800 gallons of dilute scrubbing cleanser (should be used in combination with Star San, a non-rinsing Sanitizer).
NOTE: This item weighs about 54 lbs. total, and actual Fedex Ground shipping based on your delivery zip code will be charged at checkout.
