Black spots on stainless steel kettle bottom
I dare not say that you said this pot has no problem, first of all, from the bottom of the pot pot material, there is such a situation you said, may be due to manufacturing pot material containing other ingredients, is not entirely stainless steel;Secondly, there may be the heating part of the lake too close to the bottom of the kettle, heating due to high temperature, the cooling effect of water, the chemical properties of the pot is changed, if carefully polished with sandpaper, you can remove the black class,Although this problem occurs, but it will not affect the use of temporary, as long as the temperature of the water boiling, you can achieve the purpose of sterilization.Suggest buying a water dispenser, not expensive, but also convenient
Okay, you are like this, this is stainless iron, of course there will be black spots, then kill bacteria 100 degrees to kill, this you need not worry, boiled or can be placed to give the baby to drink. Don't worry about!
The black spot should be the oxide layer. This pot is fine. Bottled mineral water is treated by filtering, ultraviolet or ozone disinfectionThe body itself contains bacteria, which are more than a kilogram of bacteria in adultsSo LZ, don't be too nervousMaybe he used 304 stainless steel, the stainless steel is not magneticBut I think it is possible to use stainless steel No. 400 above. This stainless steel has magnetic, high temperature resistance and oxidation resistanceThe method of inspection shall be checked with stainless steel liquid or destroyed part of it because the mechanical properties of stainless steel more than 400 are not good
