How to deal with rust spots on stainless steel

1. Chemical method: pickling the rusted parts to re passivate them to form chromium oxide film and restore the corrosion resistance. After pickling, in order to remove all pollutants and acid residues, proper washing with clean water is very important. After all processing, use polishing equipment to polish again, and then seal with polishing wax. For those with slight rust spots locally, you can also use a 1:1 mixture of gasoline and engine oil to wipe the rust spots with a clean rag.

2. Mechanical method: shot blasting of glass or ceramic particles. 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 under dry conditions. Using mechanical method can only clean its 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.
