Stainless steel comes from a family of materials that resist corrosion and oxidation. This gives it the ability to resist rust and unsightly blotches. 

When exposed to oxygen and moisture, stainless steel produces a thin oxide film that coats the metal. It essentially repairs itself.

Yet despite its name and resistant nature, stainless isn’t impossible to stain. The protective film will break down over time, leading to pitting and corrosion.

To maintain stainless steel, you must regularly clean its surface and ensure the steel has an adequate supply of oxygen.
