1. Chemical method: Use pickling paste or spray to help repassivate the rusted parts and form a chromium oxide film to restore their corrosion resistance. After pickling, it is very important to rinse properly with water in order to remove all contaminants and acid residues. After all the processing is complete, repolish with polishing equipment and seal with polishing wax. For minor rust spots, you can use a 1:1 mixture of gasoline and engine oil to wipe them away with a clean cloth.

2. Mechanical methods: Sandblasting, shot peening with glass or ceramic particles, burr removal, brushing, and polishing. Mechanical methods may be used to remove contaminants caused by previously removed, polished, or buried materials. All kinds of contaminants, especially foreign iron particles, can become sources of corrosion, particularly in humid environments. Therefore, mechanical cleaning of surfaces should ideally be performed under dry conditions. Mechanical methods can only clean the surface and cannot change the material's inherent corrosion resistance. Therefore, it is recommended to repolish with polishing equipment after mechanical cleaning and seal with polishing wax.
