Star San turned my bung brown...
« on: May 19, 2018, 10:14:08 PM »
So for the first time ever I was soaking my rubber stopper and starsan and within a couple of minutes it begin to turn Brown. Never had this before. It only seem to do it with a drilled bungs that I get for my Brew jacket. Anyone have any clues as to what might cause this?

That’s very LA of you.

To OP - did you have any metals in the solution too?

Now that you mention it, I did have the lid to my SS brew bucket in the same tub.

Stainless wouldn’t be an issue. I was thinking aluminum, copper or brass.

Still nice to know what caused it considering Star San is clear
