Does Stainless Steel Corrode or Rust?

Stainless steel does not stain, corrode, or rust as easily as ordinary steel. However, it is susceptible to rust staining by other objects found in the kitchen (ex. cast iron pan left in the kitchen sink will stain the sink).

Stainless steel contains additional elements such as chromium or nickel that form a protective layer on the exterior of the kitchen sink. Improper maintenance, abrasive cleaners, excessive scrubbing, and hard water build-up can all damage the protective layer, making the sink susceptible to rusting.
