Default Milky Filmy Starsan? (Not just cloudy)

Hi all, I was wondering if any of you ever had your Starsan and water solution turn milky and filmy (not just cloudy) on you? In prep for a bottling day I soaked about 25 bottles in a spare 6 gallon bucket with 1oz of starsan and 5 gallons of water for approximately 24 hours (assuming I would re-use the solution with the remaining bottles the next day). Well, 24 hours later I pulled the lid off the bucket, and my bottles were extremely slippery to the touch and had a white milky/filmy haze on them. It took a bit a washing to get rid of the film, comparable to rinsing off Oxiclean/PBW/Sun. ...As a test-repeat type of thing, this has also happened to me once before.

Has anybody has a similar experience or know what might be causing this?

Never had this. I wonder what your tap water is like. My Starsan solution may cloud after several uses, but nothing milky....

I thought about it, but haven't tested it. Good call. The SWMBO and I recently moved to Tallahassee, FL a few months ago and the water here definitely has a more "beach"/salty type of taste to it (at least compared to MS and NJ). But I really don't know what implications a "salty" water would have. Any ideas?

Could be the sodium, but not sure.....

Hard water will make starsan leave a residue. I suspect that is what you are experiencing. You probably have a higher mineral concentration in your water than your previous location.

Well, that sucks. Do you have any idea whether it effects sanitization? The residue is just nasty, but if it stills works, then so be it I guess.

...Thanks guys.

BTW, I'll try to remember to take a picture next time (because I'm sure I'll do it again, mistake or not). It's definitely a clear white residue, but I understand it might be hard to diagnose without actually seeing it.

I have seen another thread about this exact problem somewhere else in the forum, but I do not remember exactly where. The poster spoke about soaking a batch of bottles in starsan overnight to find them coated with a very stubborn white coating. I believe the end result was that he had to soak the bottles in oxyclean and scrub to remove the residue. You may want to try searching the forums and see if you can find it... If I can find the thread, I will post a link.

OOPS, It looks like I may have it backwards... I found some posts where oxyclean left a residue, and starsan was used to remove it. I guess I am no help whatsoever.... Sorry about that!
