The surface of stainless steel elements must be cleaned to maintain its aesthetic appearance and corrosion resistance. The corrosion resistance of stainless steel results from a phenomenon called “self-passivation.” The accumulation of contaminants on the surface caused by lack of or improper surface care can lead to a sudden increase in the concentration of chemical compounds that ultimately damage the passive layer. Cleaning stainless steel is therefore necessary to maintain the steel’s self-healing mechanism, which prevents the buildup of maximum concentrations of contaminants such as sulfur dioxide, chlorides, and iron contamination. Type 304 stainless steel requires maintenance with products designed for cleaning stainless steel, such as those from M3 or Wurth.
