With the economic development, the use of stainless steel has become more widespread. People are closely related to stainless steel in their daily lives. However, many people don't know much about the performance of stainless steel, and they know less about the maintenance of stainless steel. Many people think that stainless steel will never rust. In fact, stainless steel has good corrosion resistance. The reason is that a passivation film is formed on the surface. In nature, it is in the form of a more stable oxide. That is to say, although stainless steel is oxidized according to different conditions of use, it is eventually oxidized. This phenomenon is usually It's called an eclipse.


All metal surfaces exposed in the corrosive environment undergo electrochemical or chemical reactions and are evenly corroded. In the passive film on the surface of the stainless steel, the corrosion resistance is weak, and the pitting reaction is formed due to the self-excited reaction, resulting in the formation of small holes. In addition, the chloride ion approaches, forming a strong corrosive solution and accelerating the corrosion reaction rate. There is also intergranular corrosion cracking inside the stainless steel, all of which have a destructive effect on the passive film on the surface of the stainless steel. Therefore, the stainless steel surface must be regularly cleaned and maintained to maintain its gorgeous surface and prolong its service life. When cleaning the stainless steel surface, care must be taken to avoid surface scratches. Avoid using bleaching ingredients and abrasive detergents, steel wire balls, abrasive tools, etc. To remove the detergent, rinse the surface with clean water after washing.


If there is dust and dirt on the surface of stainless steel, it can be washed with soap, weak detergent or warm water.


The trademark and film on the stainless steel surface should be washed with warm water and weak detergent, and the binder component should be scrubbed with alcohol or organic solvents (ether, benzene).


Grease, oil, lubricating oil pollution on the surface of stainless steel, wipe it with a soft cloth, and then clean it with neutral detergent or ammonia solution or special detergent.


There are bleaching agents and various acids attached to the surface of stainless steel. Rinse immediately with water, then soak with ammonia solution or neutral carbonated soda solution, and wash with neutral detergent or warm water.


The rainbow pattern on the surface of stainless steel is caused by excessive use of detergent or oil. It can be washed away with mild detergent in warm water.


Rust caused by dirt on the surface of stainless steel can be washed with 10% nitric acid or abrasive detergent, or with special detergents. As long as we use the correct maintenance method, we can extend the service life of stainless steel and maintain its clean, bright and gorgeous style.
