There is polishing powder in the newly bought pot, which improves the surface performance to enough smoothness and reduces the influence of uneven surface.

When in use, the polishing powder should be removed, and a proper amount of salt should be poured into the newly bought electric kettle to sterilize and remove stains. Next, pour a proper amount of white vinegar into the newly bought electric kettle. The acidity of white vinegar can decompose the scale at the bottom of the pot. Then pour the right amount of water into the newly bought electric kettle.
