I left my teapot on the stove for about 30 minutes by accident. By the time I noticed, all the water had boiled out. So, I turned off the stove and let it cool.

When I went to put water in it again, black flakes began to come off the bottom of the pot on the inside, but I could not scrub out all the flakey stuff easily.

I have a stainless steel teapot. Are these flakes hazardous? How do I clean my pot to make sure it's safe to drink from again?

  • Actually, leaving the kettle/teapot to boil dry and then immediately fill it from the cold water tap is a way to have the limestone break, so you can rinse it out. Don't overdo this though, that would be bad for the kettle. – user34961 Apr 17 '15 at 19:56
  • What counts as overdoing it? – Seth Apr 17 '15 at 19:58

It's probably just limescale stuck to the bottom of your pot that blackened. I don't think burnt limescale is harmful, but it shouldn't be too hard to remove. You can try cleaning it using standard means to remove scale from kettles, like using vinegar.

  • I would speculate that the black colour comes from dried tea components embedded in the limescale. With no impact on the safety aspect, though. – Matthias Brandl Jan 1 at 14:23
