How to deal with rust spots on stainless steel plates?

　　"Stainless steel will not rust. If it gets rusty, it is not stainless steel. It may be a problem with the quality of the steel." In fact, this is a one-sided misconception due to lack of understanding of stainless steel plates. Stainless steel plates can also rust under certain conditions, so how should we deal with rust spots on stainless steel plates?

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

　　Mechanical methods: Sand blasting, shot blasting with glass or ceramic particles, obliteration, brushing and polishing. It is possible to mechanically remove contamination from previously removed material, polished material or buried material. All kinds of contamination, especially foreign iron particles, can be a source of corrosion, especially in humid environments. Therefore, mechanically cleaned surfaces should preferably be cleaned regularly 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-polishing with polishing equipment after mechanical cleaning and sealing with polishing wax.
