Although stainless steel has good corrosion resistance, it will eventually be oxidized if exposed in a corrosive environment for a long time. Therefore, the stainless steel surface must be regularly cleaned and maintained to maintain its gorgeous surface and extend its service life. The grease, oil and lubricating oil on the surface of stainless steel should be cleaned with a soft cloth, and then cleaned with neutral detergent or ammonia solution or special detergent. Stainless steel surface with bleach and a variety of acids attached, immediately rinse with water, and then with ammonia solution or neutral carbonated soda aqueous solution immersion, wash with neutral detergent or warm water. The products made of stainless steel are loved by the masses because of their many excellent characteristics such as corrosion resistance and high temperature resistance. In People's Daily life, we have been inseparable from stainless steel products. In all major fields, it is indispensable. Such as construction, transportation, daily life, etc. However, stainless steel products are not impervious to corrosion. Under certain conditions, it will also corrode. Therefore, we need to clean and maintain it regularly in our daily life. (Stainless steel processing) Stainless steel polishing agent is an acidic emulsion liquid, used at room temperature in the polishing of stainless steel workpiece after hot beating, can remove the oxide on the surface of the workpiece, oil, etc., so that the stainless steel is bright and clean. It has the functions of short time and good cleaning effect.

Stainless steel surface has rainbow pattern, is caused by excessive use of detergent or oil, washing with warm water neutral detergent can be washed away. Rust caused by dirt on the surface of stainless steel can be washed with 10% nitric acid or abrasive detergent, and can also be washed with special washing drugs. 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.

All the metal surfaces exposed in the corrosive environment undergo electrochemical or chemical reactions and are uniformly corroded. The parts of the passivation film on the surface of stainless steel with weak corrosion resistance form 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 corrosion reaction. There are also intergranular corrosion cracking inside stainless steel, all of which destroy the passivation film on the surface of stainless steel. Therefore, the stainless steel surface must be regularly cleaned and maintained to maintain its gorgeous surface and extend its service life. When cleaning the surface of stainless steel, attention must be paid to no surface scratches, avoid the use of bleaching ingredients and abrasive detergent, steel balls, grinding tools, etc., in order to remove the washing liquid, wash the surface with clean water at the end of the washing.
