Question By: A brand-new sink can rust for several reasons, often linked to material quality, improper care, or environmental factors. Stainless steel sinks, while resistant to rust, are not completely immune. If the sink's protective chromium oxide layer is damaged or compromised, rust can form. Scratches from abrasive cleaners or tools can create vulnerabilities where moisture and air interact with the underlying metal.
Additionally, leftover manufacturing residues, such as oil, dirt, or metal filings, can accelerate rusting if not cleaned thoroughly before use. Environmental factors, such as high humidity or exposure to hard water, can also contribute. Hard water contains minerals like iron and calcium, which can leave deposits on the sink's surface. When these deposits dry, they can form rust-like stains that mimic actual rust.
Improper cleaning habits, such as leaving wet sponges, metal utensils, or acidic substances on the sink surface, can also lead to rust. For example, a cast iron skillet left in a damp sink can transfer rust particles, creating discoloration. Learn more https://calahanbath.com/why-is-my-brand-new-sink-rusting/.
