What are the methods of cleaning and maintenance of stainless steel plates

The main components of stainless steel material is iron chromium alloy and other trace elements. Because of the excellent performance of stainless steel materials, and the corrosion resistance is generally stronger than other metals, and is still more beautiful and durable.
However, although stainless steel materials have good corrosion resistance, they are not never rusty. In fact, the stainless steel plate has a layer of passivation film, which is a stable form of oxide.
If the stainless steel plate is exposed to the corrosive environment, the surface of the plate will produce electrochemical reaction or chemical reaction, that is, to withstand the corrosion evenly. Stainless steel plate passivation film, where the corrosion resistance is weak, will generate pitting reaction due to self-excited reaction, and produce small pores. If chlorine ions are encountered, there will be very strong corrosive solutions to accelerate the rate of corrosion reaction. In addition, there will be intercrystalline corrosion cracking in the stainless steel.
All kinds of corrosion will destroy the passivation film of the stainless steel plate. Therefore, in order to ensure the beautiful surface of the stainless steel plate products and prolong the service life, we must maintain regular maintenance.
In the use of stainless steel products, we need to pay attention to the following points. The first is the attention not to scratch the surface phenomenon must be in the stainless steel surface cleaning, do not use bleach containing abrasive and lotion, do not use a steel ball or a grinding tool, and to remove the washing liquid in the washing at the end to use clean water rinse stainless steel plate. If there is dirt on the surface of stainless steel and dirt that is easily removed, it can be washed with soap, weak detergent or warm water.
When removing the trademark and sticker of the stainless steel plate, we should use warm water and weak detergent to clean it, or use alcohol or organic solvent to scrub. If the stainless steel plate is contaminated with grease, oil and lubricating oil, it can be cleaned with soft cloth and then washed with neutral detergent or ammonia solution or special detergent.
If the stainless steel board with all kinds of acid bleaching agents such as adhesion, should immediately use water to wash, and then use the ammonia solution or neutral carbonated soda solution immersion, use neutral detergent or water washing etc..
If there is a rainbow grain on the stainless steel surface, it is in fact too much use of detergent or oil caused by the use of warm water neutral detergent in order to wash away. If it is the rust caused by the dirt, 10% nitric acid or abrasive detergent can be used to wash, and special washing drugs can be used for washing. As long as the correct maintenance method is adopted, the service life of the stainless steel material can be increased and the gorgeous surface effect can be maintained for a long time.
