Rust-proof stainless steel?

Guess not!?!?

I left some stuff sanitizing (with small amount of bleech) in the kettle a day or two ago and returned today to see some rust in the kettle. And it appears where the water line reached, that the pot even corroded a little.

Note to self: kettle not for sanitizing from now on!

Gave it a vigorous scrub and MOST of the rust stains seem to be gone. Still looks like some of the metal was eaten away at the water line. ARGHHHH.

Do I need to throw this kettle out?

I may be wrong here, but I think bleach eats stainless steel for breakfast...or was that aluminum?

Someone is going to confirm or correct my comment...

It's ok to sanatize smooth surfaces with bleach but you must rinse immediately. If you've got unrinseable recesses or cracks, don't get bleach anywhere near it. It will corrode stainless if left in contact.

Your kettle is not ruined unless it's got a folded seam in it.

Folded Seam? Please expain.

Thing is, the kettle was BRAND NEW. Only brewed my FIRST batch of homebrew in it! No scrapes, no scratches. And now...

A little bleach and the pot goes to sh%t?

Wonder how good ebrew.com's return policy is?

They gave no guarantees, but I did pay nearly 40 bucks for a 12 quart pot.

Wouldn't care if I bought it from K-Mart. But being a brewing store, they should tell you their pots don't withstand bleach - the sanitizer they themselves recommend - right?

Oh, it's fun to blame someone else when you've been stupid.

But this strikes me as a case of dumb (ebrew) and dumber (caliKOng). But alas, who is the dumbest? Ain't the customer always right?

Yes, I'm guilty of one too many Ommegang Hennepin's! (Told ya I liked them heavy beers, homebrewer_99)

$40 is too high for a 12qt pot...see if you can return it. Most of the online HB stores have 20qt pots for about $40.

To answer your original question, I personally wouldn't cook with a SS pot with visible signs of corrosion.

bleach shouldn't be left over night in stainless steel. several homebrew shops even tell customers who buy used soda kegs for kegging not to let a bleach/water solution sit over night to sanitize because it will eat it up.
hate to hear the kettle got messed up.
from my HBS web page : CHLORINE BLEACH ATTACKS STAINLESS STEEL - DO NOT EXCEED AN OUNCE OF BLEACH PER GALLON OF WATER AND ESPECIALLY DO NOT LEAVE THIS SANITIZING SOLUTION IN THE KEG OVERNIGHT!!

This is a brew kettle correct? The temperatures of the brew kettle reach 212f which kills all of the bacteria. This is one of the reasons we boil the wort. If this were a fermenter I would be concerned that some little nook or cranny would evade a sanitizer and leave harmful bugs which could destroy a brew. For a brew pot, I would not be so concerned. For those of us who use modified kegs, do you really think that you get every thread of those welded on fittings cleaned? I don't personally think so. Even scratches in the stainless of a brew pot may be missed by sanitizers but the metal of the kettle which is in contact with the wort also reaches these sanitizing temperatures. Good soaking of a kettle or fermenter in a sanitizer will get into alot of cracks and crevices. IMO the worst condition exists in plastics where scratches are present. The maleability of the plastic can seal in 'bugs' and prevent the sanitizer from getting to them and the plastics are never heated to sanitizing temperatures.

If you have factual information on the contrary, please school us. I would hate to steer someone wrong based on my limited experiences and opinions.
caliKOng, unless you feel more comfortable getting a new kettle I would keep using this one myself. I would however, not use bleach in the future except as noted above (thorough rinsing immediately after use).

Chloride stress corrosion! Never use bleach with stainless. The chlorine causes very rapid etching in between the metal grains. You see it the most at the water line because the oxygen accelerates it.

If the pot isn't actually leaking you should be ok, but expect to have more trouble cleaning the pot in the future.
