The use of stainless steel has become more extensive with the development of the economy, and people are closely related to stainless steel in daily life, but many people do not 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, but in fact, stainless steel has good corrosion resistance. The reason is that a passivation film is formed on the surface, which exists in the form of a more stable oxide in nature. That is to say, although stainless steel has different degrees of oxidation according to different conditions of use, it is eventually oxidized. This phenomenon is usually called corrosion. All metal surfaces exposed in a corrosive environment undergo electrochemical or chemical reactions and are uniformly corroded. The parts with weak corrosion resistance in the passive film on the stainless steel surface will form a pitting reaction due to the self-excited reaction, forming small holes, coupled with the proximity of chloride ions, forming a strong corrosive solution and accelerating the speed of the corrosion reaction. There are also intergranular corrosion cracking inside the stainless steel, all of which destroy 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, you must pay attention to: no surface scratches will occur, avoid the use of bleaching ingredients and abrasive detergents, steel balls, grinding tools, etc. In order to remove the detergent, rinse the surface with clean water at the end of washing.
If the stainless steel surface has dust and dirt that is easy to remove, it can be washed with soap, weak detergent or warm water.
The grease, oil and lubricating oil pollution on the stainless steel surface should be cleaned with a soft cloth, and then cleaned with neutral detergent or ammonia solution or special detergent.
Bleach and various acids are attached to the stainless steel surface. Rinse with water immediately, then soak with ammonia solution or neutral carbonated soda water solution, and wash with neutral detergent or warm water.
The rainbow pattern on the stainless steel surface is caused by excessive use of detergent or oil. It can be washed off with warm water neutral detergent when washing.
The rust caused by the dirt on the stainless steel surface can be washed with stainless steel pickling passivation paste.
As long as we use the correct maintenance methods, we can prolong the service life of stainless steel and keep it clean, bright and gorgeous.
