A rolling boil causes this corrosion how?

The boil only lasted for a minute or so. There was no salt in the water. The inside is supposedly a stainless steel.

No idea.

Return for full refund/replacement.






Oh, and: you now have cancer.

Guess what wasn't actually stainless steel. :p
Actually normal steel or iron would have been fine to.
Seriously it should take years to reach that point.

Well, it's some sort of stainless steel, and it didn't have any molybdenum in it to resist pitting, that's for sure.

I suppose I can polish it out and re-passivate with citric acid, but I don't know how deep those pits are. Damn it.

That's just calcium carbonate or so, weak acid should take it, try vinegar.


(unless im blind and those are pits, not residue).

Scale isn't yellow. The centers of these pits are yellow. I'm fairly certain these are corrosion pits.

Boil some distilled water and see if you get the same results.
One possible cause is chloramine in the water, I despise the stuff, leaves spots on glasses , etc.

Doesn't look like pitting to me, just some sort of residue... but I'm looking at a picture, not at the cookware.
Have you tried any kind of cleaning agents since boiling the water?

put some balm on it

You put the balm on? Who told you to put the balm on? I didn't tell you to put the balm on. Why'd you put the balm on? You haven't even been to see the doctor. If your gonna put a balm on, let a doctor put a balm on.

It's just a pot. You put cold food in, and hot food comes out. If it still does that, I wouldn't worry about it.

Look at the spots to the right. They have reddish centers, which could be iron oxide.
Seems unlikely, this soon, if the pot is actually stainless steel. Does it say what alloy?

Definitely looks like hard water spots to me. Scrub with some vinegar and see what happens.
