Stainless steel is actually a corrosion-resistant steel. The corrosion of 304 stainless steel bar depends on the alloying elements in stainless steel bar. The reason why the stainless steel tube is resistant to corrosion is that the chromium inside it plays a big role. When the chromium content in the stainless steel bar reaches 1.2%, the chromium and the corrosive medium will form a film on the surface of the stainless steel bar in a chemical reaction. Prevent further corrosion of the internal matrix of the stainless steel bar.

Therefore, we must not destroy this layer of passivation film when cleaning the surface of the stainless steel bar, otherwise it will cause the stainless steel bar to be rusted. Therefore, when cleaning stainless steel bars, we must not scrub with a wire cleaning ball. We should use a detergent and a soft cloth to scrub.

If you find that the detergent and soft cloth can not remove the traces on the surface of the stainless steel bar, I hope you can consider using carrots.
