Hello friends,

i am here shocked to ask for help......
Yesterday i decided to bottle my beer, so i started to clean the bottles (which only needed sanitation). I put 4 tablespoons of bleach in each bottle, filled them with water and let sit for 8 hours.
Every bottle's bottom was dirtless but i noticed that ALL bottles were stained!!!
Those stains look white and opaque, and are placed of course all over the inside part of the bottles; other bottles have little stains, like pin heads.

The main thing is: my bottles were clean, and now look really messy.....
I tried also to remove this stains but it's damn difficult, they seem to be sticked to the glass.....

What do you suggest? Muriatic acid???

HELP!!!


Don Armando

Well, as you probably know now, the bleach may have etched the glass. 4T / bottle is way too much bleach.

Pehaps it is only a mineral deposit that will come off w/ acid, but i kind of doubt it. Try a vinegar soak if you have that available.

IMO the bottles may be permanently etched, hopefully someone who paid more attention in Chem 101, and 102, can give you brighter news?

Get some Star San if it is avail. in Italy. If not, you could try idophor.

I'd just get rid of them and never ever ever ever ever ever ever use bleach for homebrewing EVER again! 4 tablespoons per BOTTLE?! Holy hell dude, you'd be better off using that much for 5 gallons of water!

Get iodophor, star-san.... I'd even pee in my bottles to sanitize them (or give it to BMC drinkers! They wouldn't know the difference) before I used bleach

Bleach is fine for cleaning or sanitizing, but you used way to much. You may have ruined the bottles by soaking them in that concentration.

I don't think bleach will etch glass, however, I am not at all sure about that. I do agree that four tablespoons is way, way to much. More like 1/4 cup in five gallons would be suitable for sanitizing.

Something else is going on here. The chlorine is possibly reacting with something in the water and leaving deposits on the glass. I'm with those who suggest rinsing them with white vinegar or Star San (acid solution).

You said that you had previously cleaned the bottles. What type of cleaner did you use. I think the deposits may have been there before the bleach soak, but were not visible while the bottles were wet. I've had Oxyclean leave deposits on my bottles after a long soak. These were easily removed with a white vinegar rinse in my case.

Yes it is, but in five gallons of water, not per bottle!

I'm thinking almost the same. While I'm not totally sure that bleach will/will not corrode glass it may just have brought some other growth to light after such a concentrated soak. He said that it wasn't impossible to get these stains off, but, d**n hard which in the case of corrosion ,the material would have been marred or removed. I'm thinking if he can after some effort get the spots off that it may not be corrosion, but some very tenacious mold or something that was not evident prior to the soak, and I feel he may benefit from at least trying your idea to soak them in vinegar or something before giving them the toss. Just a thought. Good luck!

The reason I don't think that bleach will etch glass is that long ago, Clorox was, at one time, sold in glass jugs. I've put full strength bleach in glass containers more than a few times without any visible etching occuring.
