Under normal use, stainless steel sink products will not rust. However, some customers' sinks will have "mold growth", "floating rust" or "white film" on the surface of the sink after a short period of use. What is going on? There are two reasons for this situation: 1. The water in the water pipes is rusty. As we all know, if the water pipes have not been used for a period of time or have just been renovated, a stream of yellow water will come out when the faucet is turned on. This is water containing impurities and rust. If the water is left in the basin and not rinsed in time, the impurities and rust will be deposited and adhere to the surface of the sink, causing rust, giving the illusion that the sink is rusty. 2. If the sink is not thoroughly cleaned after use, a lot of dirt of various ingredients adhering to the surface will also cause "mold growth", "floating rust" or "white film" and other phenomena. The above also tells us that stainless steel sinks also need maintenance, so we remind everyone to keep the water source clean and clean the sink in time after use to avoid the risk of mold and rust. If rust and mildew have already occurred, don’t worry. One can be cleaned with toothpaste, and the other can be scrubbed with talcum powder and water. This will definitely give you a brand new and beautiful sink. Generally, this problem will disappear after two months of use!
