The use of stainless steel has become more widespread with the development of the economy. People are closely related to stainless steel in daily life, but many people don't know much about the performance of stainless steel. The maintenance of stainless steel is known to a lesser extent. Many people think that stainless steel will never rust. In fact, stainless steel has good corrosion resistance because the surface forms a purified film. In nature, it exists in the form of a more stable oxide. That is to say, although the stainless steel is different in oxidation depending on the conditions of use, it is eventually oxidized. This phenomenon is usually called corrosion.


All metal surfaces exposed to corrosive environments are electrochemically or chemically reacted, and are uniformly corroded. The corrosion-resistant part of the purified film on the surface of stainless steel forms a pitting reaction due to self-excitation reaction, and generates small holes, plus The aerobic ions are close to each other, forming a strong corrosive solution that accelerates the rate of corrosion reaction. There is also intergranular corrosion cracking inside the stainless steel, all of which destroys the purified film on the stainless steel surface.

Therefore, the stainless steel surface must be regularly cleaned and maintained to maintain its gorgeous surface and extend its service life. When cleaning the stainless steel surface, care must be taken not to cause surface scratching. Avoid using bleaching ingredients and abrasive washing liquid, steel balls, grinding tools, etc., to remove the washing liquid, and rinse the surface with clean water at the end of washing.

The stainless steel surface is dusty and easy to remove dirt. It can be washed with a weak soap detergent. The binder component is scrubbed with alcohol or organic solvent (ether, benzene).

The grease on the surface of stainless steel is contaminated with oil and oil. After wiping with a soft cloth, it is washed with a neutral detergent or ammonia solution or with a special detergent. The surface of the stainless steel is bleached and various acids are attached. Rinse immediately with water, dip with ammonia solution or neutral carbonated soda solution, and wash with neutral detergent or warm water.

The stainless steel surface has a rainbow pattern, which is caused by excessive use of detergent or oil. It can be washed with warm water detergent when washing. The rust caused by dirt on the surface of stainless steel can be washed with 10% nitric acid or grinding detergent, or it can 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 keep it clean, bright and gorgeous.
