"Stainless steel does not rust, and rust is not stainless steel. It may be a problem with the steel." In fact, this is a one-sided misconception about the lack of understanding of stainless steel. Stainless steel can also rust under certain conditions, so how should we deal with rust spots on stainless steel?
Chemical method: Use pickling paste or spray to assist the re-passivation of the rusted parts to form a chromium oxide film to restore the corrosion resistance. After pickling, in order to remove all the contaminants and acid residues, it is necessary to rinse properly with clean water. important. After all treatments, re-polishing with polishing equipment and sealing with polishing wax. For those with slight rust spots, you can use a 1:1 gasoline and engine oil mixture to wipe off the rust spots with a clean cloth.
Mechanical methods: sandblasting, shot blasting with glass or ceramic particles, annihilation, brushing and polishing. It is possible to use mechanical methods to wipe off the contamination caused by previously removed materials, polishing materials or oblivious materials. All kinds of pollution, especially foreign iron particles, can become a source of corrosion, especially in humid environments. Therefore, mechanically cleaned surfaces should be properly cleaned 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.
