1, the chemical method: with acid pickles or spray to help re-pass the corrosive parts of the formation of chromium oxide film to restore its corrosion resistance, pickling, in order to remove all the contaminants and acid residues, with water appropriate Flushing is very important.
After all the treatment with polishing equipment to re-polished, with a wax can be closed. On the local mild rust can also be used 1: 1 gasoline, oil mixture with a clean cloth wipe rust can be.
2, mechanical methods: sandblasting clean, with glass or ceramic particles shot peening, annihilation, scrubbing and polishing. It is possible to wipe away the contaminated material, the polishing material, or the annihilation material. All kinds of pollution, especially foreign iron particles, may become the source of corrosion, especially in humid environments.
Therefore, the mechanical cleaning of stainless steel surface should be the best dry conditions should be carried out under the clean-up. The use of mechanical methods can only clean up its surface, can not change the corrosion resistance of the material itself. It is therefore recommended that the machine be cleaned with a polishing device and then polished with a polished wax.
