Is the small rust spot on the bottom of the Xiaomi Double Wall Electric Kettle a sign of rust?
The body (interior) of the Xiaomi Double Wall Electric Kettle is made of 022Cr17Ni12M02 (SUS316L), which has an excellent anti-rust effect and can fully meet the normal usage conditions for the electric kettle. Most of the time, the small spots on the electric kettle belong to the limescale. If you find yellow spots, pockmarks, rust spots, and so on, you can try to use citric acid or vinegar to soak and clean them. If the above cleaning method is not effective, you can try to wipe with sandpaper or dishcloth to deal with them. A small amount of rust is often accompanied by our life, and will not affect human health.
For your reference, please check the principle of rusting stainless steel:
Stainless steel is a crystal solid composed of similar atomic arrangements. In addition to the iron element, stainless steel also contains other metal elements, such as chromium, nickel, titanium, and so on. Among them, the elements of chromium and nickel have the function of rust prevention. They form a protective film (passive oxide layer) to prevent stainless steel from rusting.
The water quality varies in the different areas. Some water containing high levels of dissolved minerals will have impurities. After being heated, the impurities will form precipitates, which will destroy the protective film of stainless steel making it rusty.
