Stainless steel needs to be regularly cleaned to maintain its aesthetic appeal and to prevent corrosion. A corrosion protection film exists on the surface of stainless steel and is formed when oxygen from the atmosphere combines with the chromium in the stainless steel to form a passive chromium oxide film. Not regularly cleaning your stainless steel products can lead to corrosion as the product can become contaminated by dirt and other materials, which then become trapped against the surface creating corrosive agents and reducing the effectiveness of the corrosion protection film.
Stainless steel is easily cleaned and thrives with frequent cleaning. Unlike other, softer materials stainless steel cannot be worn out by excessive cleaning. The effects of surface or pattern roughness, grain or pattern orientation, and designs that allow for maximum rain cleaning should be considered.
