Scrubbing the surface with steel wool or wire brush: When this process is used to clean stainless steel, particles are embedded onto the surface. Rust can form when these particles are exposed to humid air or moisture. For example, chemicals that are used for cleaning concrete or windows can land on the stainless steel surface and react with the air to form rust.
Due to the chromium oxide layer stainless steel can be self-healing, but maintenance is required. Wash the surface and rinse with fresh water and a clean cloth, then dry completely. Another alternative is to purchase a special cleaning kit or have the products refinished. Our experts are here to help. We can recommend what type of stainless steel is right for your environment and budget, as well as provide cleaning and repair tips.

Because the film forms so readily and tightly, even only a few atomic layers reduce the rate of corrosion to very low levels. The fact that the film is much thinner than the wavelength of light makes it difficult to see without the aid of modern instruments. Thus, although the steel is corroded on the atomic level, it appears stainless.
As such, this film, otherwise known as rust, achieves sufficient thickness to make it easily observable soon after exposure to water and air. In summary, stainless steel does not rust because it is sufficiently reactive to protect itself from further attack by forming a passive corrosion product layer. Other important metals such as titanium and aluminum also rely on passive film formation for their corrosion resistance.
Because of its durability and aesthetic appeal, stainless steel is used in a wide variety of products, ranging from eating utensils to bank vaults to kitchen sinks.
