I.Stainless steel sinkWhat are the possible causes of yellowing?
1、Stainless steel sinks turning yellow is usually due to rust. Stainless steel sinks are generally not prone to rusting. The appearance of rust stains is usually after renovation, as new homes often have iron filings and rusty water in the newly installed pipes. These impurities settle on the surface of the sink, forming rust stains.
2. Construction workers frequently pour chemical paints into sinks without cleaning them promptly, or frequently immerse heavy metal tools in them. This is also a cause of rust formation in the sinks.
3. Frequent use of the kitchen sink without proper maintenance can lead to the accumulation of organic substances such as lemon juice, vegetables, and soup on the stainless steel surface. In the presence of water and oxygen, these organic substances form organic acids, which can corrode the metal surface over time, resulting in rust spots. This is because the protective film on the stainless steel surface has been damaged.
