How to deal with rust in stainless steel?

1, chemical methods
      The use of a pickling paste or spray to assist the re-passivation of the corroded part to form a chromium oxide film restores its resistance to corrosion. After pickling, it is important to flush properly with water in order to remove all contaminants and acid residues. After everything is processed, it is polished again with a polishing device and closed with a polishing wax. For those with slight rust on the spot, a 1:1 mixture of petrol and oil can be used to wipe off rust with a clean rag.

2, mechanical method
      Blast cleaning, shot blasting with glass or ceramic particles, annihilation, brushing and polishing. Using mechanical methods it is possible to wipe off the contamination caused by previously removed materials, polishing materials or annihilation materials. All kinds of pollution, especially foreign iron particles, can be a source of corrosion, especially in humid environments. Therefore, the mechanical cleaning surface should preferably be cleaned in a dry condition. The mechanical method can only clean the surface and cannot change the corrosion resistance of the material itself. It is therefore recommended to re-polish with a polishing machine after mechanical cleaning and close it with a polishing wax.
