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 cleanser, to sanitize the cleaned equipment. When diluted as instructed, Star San does not require rinsing, and will not stain. 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 one quart bottle of Star San will make up to 160 gallons of dilute working solution that does not need to be rinsed after use. Use by itself, or in conjunction with PBW powdered brewery cleaner (to remove deposits before the final rinse).
RESTRICTED SHIPPING: Ground shipment only to lower 48 states. No air shipments, and no postal shipments (no shipments to Zone C).

I don't want to be judging people, but if you need to read a customer review of Star San before buying it, I can't imagine how many melons you must handle before you pull the trigger and purchase one. It's Star San, man!
