There is a circle of printing at the bottom of the electric kettle. Is it poisonous? Does it affect your health?
This is calcium oxide, no poison, the body proper absorption to the body is good, just looks bad, so sometimes people will be washed
No, not at all! If there is one, then it will not sell
Furring. Normal water quality is not good in the case, such as in some areas also use deep groundwater, it will naturally have scale. Not only a kettle, but even a thermos bottle. In addition, these scales can be removed using vinegar, does not recommend strong wipe. It's not good to rub badly. But as the kettle is made of metal, the right amount of vinegar will do. Not excessive. A dozen drops of vinegar, plus a little water, slowly flow in the surface of the scale, and gradually formed the reaction on the line, back and forth a few times. The effect is very good. Not only the bottom, I believe the inner wall also has, the method is same ~ life common sense pulls!
