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?

I try not to discuss my bung on the Internet.


...but I’ve never heard of this discoloration.

You can bleach your bung

Wouldn't that burn Jim?

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.

what is wrong with a brown bung? who cares what color it is as long as it functions correctly.

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