If the stainless steel surface contains dust of other metal elements or attachment of dissimilar metal particles. In humid air, the condensed water between the attached material and the stainless steel connects the two into a micro battery, triggering an electrochemical reaction. The protective film is destroyed, which is called electrochemical corrosion.The surface of the stainless steel adheres to the organic juice (such as melon, noodle soup, etc.), which will constitute an organic acid in the presence of water and oxygen, and the organic acid will corrode the metal surface.The surface of the stainless steel adheres to acid, alkali, and salt substances (such as splash of alkaline water and lime water), will cause local corrosion.In polluted air (such as the atmosphere containing a large amount of sulfide, carbon oxide, nitrogen oxide), sulfuric acid, nitric acid, acetic acid liquid spots will form in the condensed water, causing chemical corrosion.Please take care to avoid the damp environment and avoid washing with steel balls and bleaching agents or abrasives.Rinse with neutral cleaner. Dry them after washing.Please do not scratch the surface with hard material such as steel scrubber.Please store them in dry cool places and avoid direct sunlight.Avoid the production of acidic, alkaline foods.Please attention there is no bad stainless steel (except for fake and shoddy), only the unsuitable environment
