Why does stainless steel rust? When a brown rust (spot) appears on the surface of a stainless steel tube, people are surprised: "The stainless steel is not rusted, rust is not stainless steel, and there may be a problem with the steel." In fact, this is a one-sided misconception about the lack of understanding of stainless steel. Stainless steel will rust under certain conditions.
Stainless steel has the ability to resist atmospheric oxidation - that is, stainless, but also has the ability to corrode in media containing acid, alkali, and salt - that is, corrosion resistance. However, the corrosion resistance of the steel varies with the chemical composition of the steel itself, the interaction state, the conditions of use, and the type of environmental media.

In order to extend the service life of the water tank, customers should pay attention to the correct use and maintenance of the water tank after purchasing the water tank. The following suggestions are recommended:
☆ When decorating a house, do not pour the waste water after the decoration materials or flushing the decoration materials in the sink, so as to avoid oxidation of the surface of the sink due to the iron or corrosive elements contained in the decoration materials, thus causing the sink to rust.
☆ In order to protect newly purchased sinks from being seriously corroded during the renovation process, a layer of animal or vegetable oil may be applied to the surface of the sink to isolate the surface of the sink from corrosive substances.
☆ Do not pour acid, alkali or other corrosive liquids into the sink when using the sink. If you accidentally drop the photographic drug or solder melt in the sink, rinse it with clean water immediately.
☆The sink should be cleaned regularly. Please use sponge or cotton cloth to clean the sink. When cleaning with a detergent, use a mild detergent and gently scrub.
☆ After the water tank is used, it should be cleaned and wiped with clean water. Do not allow water droplets to remain on the surface. High iron content water may cause brownish red water marks on the surface of the water tank.
☆ The retention of moisture will lead to the occurrence of mineral deposition. In this case, a low concentration of vinegar solution can be used to remove this deposition, and it is finally completely cleaned with fresh water.
☆ Do not scrub the sink with a steel wire ball. Scrubbing the steel wire ball will leave scratches on the surface of the sink and cause metal particles to adhere to the wall of the sink, resulting in rust spots.
☆ Clean the sink to avoid the use of rough brushes, so as not to scratch the surface of the sink.
☆ Do not use a rubber pad in the sink because the dirt under the rubber pad is difficult to clean.
☆ If there is water spot in stainless steel sink, it can be scrubbed with neutral detergent powder or cleaning agent.
