Summary: Under normal conditions of use, we will not rust when we use stainless steel sinks, but if we use them incorrectly, it will cause the stainless steel sinks to rust, causing "mold growth" and "floating rust" on the surface. Is the stainless steel sink also rusting? Below, Xiaobian Archie will share with you the reasons and solutions for stainless steel sink rust.

      When brown rust spots (spots) appear on the surface of stainless steel pipes, people are greatly surprised: "Stainless steel does not rust, and if it rusts, it 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 also rust under certain conditions.

      Stainless steel has the ability to resist atmospheric oxidation—that is, rust resistance, and also has the ability to corrode in media containing acids, alkalis, and salts—that is, corrosion resistance. But the size of its anti-corrosion ability is changed with the chemical composition of its steel itself, the state of mutual addition, the conditions of use and the type of environmental media. For example, 304 steel pipe has excellent rust resistance in a dry and clean atmosphere, but if it is moved to the seaside area, it will rust soon in the sea fog containing a lot of salt; and 316 Steel pipes performed well. Therefore, it is not any kind of stainless steel that can resist corrosion and rust in any environment.

      Stainless steel is a very thin, firm, fine and stable chromium-rich oxide film (protective film) formed on its surface to prevent the continuous infiltration and oxidation of oxygen atoms, and obtain the ability to resist rust. Once the film is damaged continuously for some reason, oxygen atoms in the air or liquid will continuously infiltrate or iron atoms in the metal will continue to separate out, forming loose iron oxide, and the metal surface will be continuously corroded. There are many forms of damage to this surface film, the most common in daily life are the following:

 1. On the surface of stainless steel, there are deposits of dust or heterogeneous metal particles containing other metal elements. In humid air, the condensed water between the deposits and the stainless steel connects the two into a micro-battery, which triggers an electrochemical reaction. , the protective film is damaged, called electrochemical corrosion.

       2. Organic juices (such as vegetables, noodle soup, sputum, etc.) adhere to the surface of stainless steel. In the presence of water and oxygen, organic acids are formed, and organic acids will corrode the metal surface for a long time.

       3. The surface of stainless steel adheres to substances containing acids, alkalis and salts (such as alkaline water and lime water splashing from the decoration walls), causing local corrosion.

       4. In polluted air (such as the atmosphere containing a large amount of sulfide, carbon oxide, nitrogen oxide), when encountering condensed water, it will form sulfuric acid, nitric acid, and acetic acid liquid points, causing chemical corrosion.

       The above conditions can cause damage to the protective film on the stainless steel surface and cause rust. Therefore, in order to ensure that the metal surface is as bright as possible and not rusted, we suggest that the decorative stainless steel surface must be cleaned and scrubbed frequently to remove attachments and eliminate external factors that cause modification.

Rust removal method for stainless steel sink

       Remove with molten steel; wet the rust of the steel basin with water; wipe off the rust with a cotton swab or cotton cloth and a little molten steel; Can be wiped dry;

1. Water containing heavy metals will cause discoloration or rust spots in the sink

      ① Dilute 4 times with stainless steel brightener (can remove surface stains and rust)

      ② Scrub repeatedly with a towel until the surface is rusted

      ③ Wash it with hot water, and after drying, spray with anti-rust water to keep the surface smooth and clean.

2. Mineral deposits, water spots

       Use low-concentration vinegar solution or decontamination powder to remove, and then completely clean with clean water. The lumpy rust caused by not washing in time after being stained with strong acid-base substances, or not being washed cleanly

      ①Rinse with water immediately

      ②Use ammonia solution or neutral carbonated soda solution vinegar, stainless steel treatment agent to wash molten steel, etc.

      ③ Wash with neutral detergent or warm water

3. Due to the house decoration and improper protection, the residual rust in the water pipe is a spot-like rust spot left on the stainless steel sink

      ①Scrub with toothpaste

      ②Rinse with cold water and dry with cotton cloth. Surface dust and easy-to-remove dirt can be washed with soap, weak detergent or warm water

4. Grease, oil and lubricating oil pollution on stainless steel surface

      ①Wipe clean with a soft cloth.

      ②Clean with neutral detergent or ammonia solution or special detergent. The stainless steel surface has rainbow patterns, which can be washed off with warm water or neutral detergent when washing

How to maintain stainless steel sink

      1. After the sink arrives, if the house is still being renovated, pay attention to always open the windows for ventilation, so as to avoid the corrosive gas emitted by the decoration materials from oxidizing the surface of the sink, thus causing the sink to rust.

      2. For newly renovated customers, you can apply a layer of oil on the surface of the sink, which will be less likely to rust than ordinary sinks; you can also use the same method when the sink is not used for a long time! And if there is rust, use Wipe the toothpaste at home, it can play a good rust removal effect.

      3. After using the sink, try to rinse it with clean water and dry it. Do not let water droplets remain on the surface of the sink. Water with high iron content may cause brown-red marks on the surface. That's it.

      4. If the water that has not been wiped dry has produced water stains that are difficult to remove, you can use a low-concentration vinegar solution to remove this deposit, and then wash it completely with water.

     5. To clean the sink frequently, only use sponge, cloth and neutral detergent
