1. Mechanical removal: For rust spots on the surface, you can use tools such as sandpaper, wire brushes, or grinding wheels to remove them. Be careful not to over-grind to avoid damaging the stainless steel surface.

2. Chemical cleaning: You can use a special stainless steel cleaning agent for cleaning. Apply the cleaning agent to the rust spots, let it stand for a while, and then wipe it clean with a cloth. If the rust spots are heavy, you can heat the cleaning agent to a certain temperature to improve the cleaning effect.

3. Electrochemical rust removal: For more stubborn rust spots, you can use electrochemical rust removal. Connect the rust remover to the power supply, soak the rust spots in the rust removal liquid, and remove the rust spots after some time.

4. Polishing: For the stainless steel surface that has been rusted, you can polish it to restore its bright surface.

1. Chemical method
Use pickling paste or spray to assist the rusted parts to passivate again to form a chromium oxide film to restore its corrosion resistance. After pickling, it is very important to rinse with clean water properly to remove all pollutants and acid residues. After all treatments, re-polish with polishing equipment and seal with polishing wax. For local slight rust, you can also use a 1:1 gasoline and engine oil mixture with a clean rag to wipe off the rust.

2. Mechanical method
Sandblasting, cleaning with glass or ceramic particles, annihilation, brushing, and polishing. Mechanical methods may wipe off the pollution caused by previously removed materials, polishing materials, or annihilation materials. All kinds of pollution, especially foreign iron particles, may become a source of corrosion, especially in humid environments. Therefore, the mechanically cleaned surface should preferably be cleaned formally under dry conditions. The use of mechanical methods can only clean the surface and cannot change the corrosion resistance of the material itself. Therefore, it is recommended to re-polish with polishing equipment after mechanical cleaning and seal with polishing wax.
