Is it ok to store Starsan in a SS kettle temporarily? I did so for a few days and noticed some brown “stuff” come off the kettle when I scrubbed it with a sponge. Could have been from an earlier brew, but just curious if it was degrading the metal somehow.
it’s not degrading the metal, just cleaning it a bit. a lot of folks store star san in a keg for long periods so I’m pretty sure it’s okay.
I believe starsan is ok for SS even if it hasnt been passivated:) If you feel unsure contact Five Star, their customer service is outstanding!
Cheers,
Jeff
That “stuff” is just a thin layer of beerstone. Instead of elbow grease and a BLUE scrubbie, I regularly just throw some spent starsan in the kettle to loosen that stuff up. Same effect as acid cleaner #5.
