    In the break room at work, there is a tea kettle that has some unappealing discoloration. I would like to use it, and lots of people do, but I find it terribly unappealing.

    I can't remove it with soap, and my fingernail has no effect. I can't even feel it, so it doesn't seem like buildup. What causes this, does it adversely affect health or water taste, and is there a way to remove it or improve this teakettle?

  • See this previous post that explains how to clean an electric kettle. The suggestions include boiling citric acid, vinegar, or descaling solution in the teapot.

    Presumably these are impurities from the water that have solidified on the plastic. It is possible that the lack of texture that you mention is because the impurities have bonded with the plastic.

  • using purified water will help. distilled or filtered. after you clean it with vinegar. otherwise it might be possible that someone is putting his or her tea bag (or other) in the pot and that can cause discoloration.

  • , it never works anymore. I found a few related questions here, but they don’t quite apply (they talk about different bowls, different temperatures, etc., but like I said, it used to work).

  • I love feta cheese, and I can't get enough of it, just like my family. But unlike them, I only eat it raw. I can't stand the grilled feta sandwiches my mother eats every morning for breakfast, and the reason is that, when the feta is grilled, it turns terribly salty and sharp. The reason can't be just melting, because I enjoy lots of dishes which are baked with feta in the filling, as long as it doesn't get any direct heat. What is the reason for this taste change? Can it be prevented?
