　　What to do if the stainless steel chain hoist rusts

　　1. Chemical methods

　　Use acid cleaning paste or spray to assist the rusted parts to passivate again to form chromium oxide film to restore their corrosion resistance. After acid cleaning, in order to remove all pollutants and acid residues, it is very important to properly rinse with clean water. After all processing, use polishing equipment to re polish and seal with polishing wax. For areas with slight rust spots, a 1:1 mixture of gasoline and engine oil can be used to wipe off the rust spots with a clean cloth.

　　2. Mechanical methods

　　Sandblasting, shot blasting with glass or ceramic particles, immersion, brushing, and polishing. It is possible to use mechanical methods to wipe away contamination caused by previously removed materials, polishing materials, or annihilated materials. Various types of pollution, especially foreign iron particles, can become sources of corrosion, especially in humid environments. Therefore, it is best to perform formal cleaning on mechanically cleaned surfaces under dry conditions. The use of mechanical methods can only clean the surface and cannot alter 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
