i found a bottle of star san that i'm pretty sure is 8 years old. never been opened. do you think it's still ok?
does it look like starsan? if so I would say use it.
i think so, i have never actually used it. it's a light gold color. i use one step, all the time, but i am tired of having to make big batches every time, and i want to make the star san spray bottle thing.
I'm sure it's fine it's acid,
