STAINLESS STEEL PREP
PRE-CLEAN
PASSIVATION
CLEANING AND SANITIZING
Prior to first time use, thoroughly wash all surfaces of the Ss Brew Kettle, including all valves and
fittings, with Tri-Sodium Phosphate (TSP) in hot water, mixed to the manufacturer’s recommendations.
Scrub with a soft terry cloth, and after the initial TSP wash, rinse thoroughly and dry all surfaces.
It’s good practice to periodically passivate all stainless steel equipment with an acid based solution to
establish a uniform passive oxide layer that will maximize corrosion resistance. Following the pre-clean
step, fill the Ss Brew Kettle BME with Star San at a concentration of 1 ounce per gallon at 70- 80°F for
30 minutes. Moving forward, for best stainless performance, passivation should be performed at least
once a year or anytime you believe you may have inadvertently scratched the surface. ***Save this Star
San solution to perform the pressure testing step covered later in this guide.
As part of a regular cleaning regimen, both pre and post-fermentation, wash the interior surfaces of your
Ss Brew Kettle with an alkali cleaner such as PBW at a ratio of 0.75 ounce per gallon. Then sanitize
with Star San or another acid based sanitizer per the manufacturer’s recommendations.
