Star San - Galvanized Steel - Oops...
« on: April 02, 2010, 04:02:30 PM »
had to sanitize some bottles for a batch today (god I forgot how much I hate bottling).

Not thinking, I used one of those steel tubs you get at Walmart/Home Depot for icing down beers.  

Anyway, I used that as my star san dunk bucket - did I just ruin everything?

Towards the end, the star san was a bit hazy.

I forget, what's the pH of StarSan? The FDA now says galvanized steel is safe for use with food if it's not too acidic, like  below 5.5 -- I'd have to look it up again.
It's such a fine line between stupid and clever.

The pH is lower than 5.5.  I believe its under 4.

For Star San you actually want the pH to be under 3. I'd rinse and re-sanitize - it seems like minimal effort for the peace of mind.

i don't think you understood - already bottled... :'(

i taste tested one of the CPF bottles I filled and it seems fine.

I can't imagine that the reaction would be all that significant in 1-2 hours time.  plus the bottles and equipment was let dry beforehand - not like I'm drinking the star san solution.

Galvanized = Zinc
Zinc is dissolved by acid and excessive Zinc is toxic. I wouldn't risk it.
Wikipedia has a pretty good write up. The toxicity part is about 2/3 of the way down.

agreed, but were talking about stuff I rinsed with, not drinking the stuff.

granted, the bottles weren't bone dry (some foam bubbles were still present) but they were pretty dry.

It might take the "metallic off flavor" to a new level ;D

well, I just took one of the bottles I CPFed against a sample right off the keg.

Tastes/Smells identical.

I think i'm worrying about nothing, though I won't ever use that tub again.

I'll go out on a limb; your ethyl alcohol consumption far outweighs a probably not detectable level of zinc consumption... ;D

LOL!

I'm thinking I'm fine.  Lesson learned.

I'm hoping so. Now, if someone with specific knowledge says don't drink 'em, I would heed that advice. Good luck!

First give a six-pack or so to some "friends", wait a week or so and then ask them how they're feeling.  :D
