How to Remove Rust Spots on Stainless Steel Pipes?

Stainless steel pipes are popular for its beautiful appearance, corrosion resistance characteristics, and not easily damaged. But when brown rust spots appear on the surface of stainless steel pipes, people will be wondering: Why does "stainless steel" rust? In fact, this is a wrong points of stainless steel, because stainless steel will rust under certain conditions. So how to clean the rust spots on the steel pipe?

1. Chemical methods

Use pickling paste or spray to assist the re-passivation of the rusted parts to form a chromium oxide film to restore corrosion resistance. In order to remove all contaminants and acid residues, it is very important to rinse with clean water. After all treatments after pickling, re-polishing with polishing equipment and sealing with polishing wax. For the slight rust spots, you can use 1:1 gasoline and engine oil mixture to wipe off the rust spots with a clean cloth.

2. Mechanical method

Sandblasting, blasting with glass or ceramic particles, annihilation, brushing and polishing. It is possible to use mechanical methods to wipe off the contamination caused by the previously removed materials, polishing materials or oblique 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 cleaned in dry conditions. The use of mechanical methods only clean the surface, and cannot change the corrosion resistance of the material. Therefore, it is recommended to re-polish with polishing equipment after mechanical cleaning and seal with polishing wax.
