Corten steel is a unique and durable weathering steel that develops a protective patina of rust over time that safeguards the base metal from corrosion. The steel arrives in its natural grey state and will build its patina over a period of weeks or months. If you want to speed up this weathering process, all you need are some common household items: salt, vinegar, and hydrogen peroxide.
