Due to its strength, longevity, and corrosion resistance, stainless steel is a common material choice for faucets. It is not entirely resistant to rusting, though.
Exposure to strong chemicals, such as chlorine, is one reason why stainless steel faucets rust. Stainless steel can develop surface pitting from chlorine, which increases corrosion potential. Because of this, it is not advised to use bleach or other abrasive cleansers on surfaces made of stainless steel.
The presence of saltwater or settings with high humidity are other causes of rusting in stainless steel faucets. As a result, the steel may lose its coating of chromium oxide protection, making it more susceptible to rusting. Marine-grade stainless steel, which has greater amounts of nickel and molybdenum, should be used to make stainless steel faucets in order to prevent rusting in saltwater settings.
Rusting in stainless steel faucets can also result from improper installation or repair. Incorrect installation of the faucet can put stress on the metal, resulting in corrosion and cracks. Similar to this, improper faucet repair can allow water to leak into cracks and cause rusting.
In conclusion, even though stainless steel faucets are made to be rust-resistant, they are not fully impervious to corrosion. Rusting can be caused by exposure to strong chemicals, saltwater, or settings with high humidity, as well as by incorrect installation or repair. Use mild cleaning agents sparingly, stay out of harsh situations, and make sure your stainless steel faucets are installed and repaired properly to avoid rusting.
