Regular cleaning of stainless steel is necessary to maintain its corrosion resistance. Dirt, grime, and other contaminants can interfere with the formation of the chromium oxide layer, reducing the material’s corrosion resistance. Cleaning stainless steel regularly helps to remove these contaminants and ensure that the chromium oxide layer can form properly. This is especially important in harsh environments, such as cooling towers, closed circuit coolers, or evaporative condensers, where corrosion can occur more quickly.
