Stainless steel material appears rust spot how to deal with?

1. Chemical methods

Use pickling paste or spray to assist its rust parts to passivate and form chromium oxide film to restore its corrosion resistance. After pickling, in order to remove all pollutants and acid residues, it is very important to properly rinse with water. After all treatment, use polishing equipment to polish again, with polishing wax can be closed. On the local slight rust spot can also be used 1:1 gasoline, oil mixture with a clean cloth to wipe off the rust spot.

2. Mechanical methods

Sand blasting, shot peening with glass or ceramic particles, annihilation, scrubbing and polishing. It is possible to mechanically erase contamination caused by previously cleaned, polished or annihilated materials. All kinds of pollution, especially foreign iron particles, can be sources of corrosion, especially in humid environments. Therefore, the best mechanical cleaning surface should be regular cleaning under dry conditions.

The use of mechanical methods can only clean the surface, 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.
