The stainless steel filter mesh has a rainbow pattern on the surface, which is caused by excessive use of scrubbing agent or oil. It can be washed away with warm water-based scrubbing agent when scrubbing. The rust caused by stainless steel surface dirt can be scrubbed with 10% nitric acid or abrasive scrubbing agent, or with special scrubbing chemicals.

　　As long as we use the correct method of maintenance, we can extend the service life of stainless steel, adhere to its clean, bright, magnificent gas volume, due to self-excited response, it forms a pitting corrosion response, generates small holes, and is close to chloride ions.

　　 constitutes a strong corrosive solution, accelerating the speed of corrosion response. The stainless steel filter and the intergranular corrosion cracking inside the stainless steel, all of which have a destructive effect on the passivation film of the stainless steel surface. Therefore, it is necessary for the stainless steel filter to stop the punctual cleaning and maintenance of the stainless steel surface.

　　 adheres to its magnificent appearance and extended life. When cleaning the surface of stainless steel, it is necessary to be careful not to scratch the surface, to prevent the use of bleaching ingredients and abrasives, scrubbing liquid, steel balls, abrasives, etc. In order to remove the scrubbing liquid, wash the surface with clean water after washing.
