How to maintain stainless steel?

The use of stainless steel with the economic development has become more widespread, people in everyday life is closely related to stainless steel, but many people do not know much on the performance of stainless steel, stainless steel maintenance will know even less about it. Many people think that stainless steel is never rust, in fact, good corrosion resistance of stainless steel. The reason is a passivation film formed on the surface, it is in nature to form more stable oxides in other words, according to the conditions of use of stainless steel although the degree of oxidation is not the same, but have been oxidized, this phenomenon is commonly called eclipse.

Exposed to the corrosive environment of the metal surface of all electrochemical reactions occur, or chemical reaction, even subject to corrosion. Surface passivation film of stainless steel corrosion resistance among the weak portion, formed by the reaction due to self-excited pitting reaction holes, coupled with chloride ions close to form a strong caustic solution, accelerated corrosion reaction rate. There are stainless steel to intergranular corrosion cracking inside, all of them, the passive film on the stainless steel surface damaging effects occur.

Therefore, the stainless steel surface cleaning and maintenance must be carried out regularly in order to maintain its gorgeous surface and prolong life. Cleaning stainless steel surfaces must be careful not to scratch the surface of the phenomenon occurs, avoid the use of bleach ingredient and the washing liquid abrasives, steel balls, grinding tools, to remove the washing liquid, washing and then clean water rinse at the end surfaces. Stainless steel surface dust and dirt easily get rid of objects that can be used with soap, weak detergent or warm water wash. Stainless steel surface trademarks, foil, with warm, weak detergent to wash the binder composition, use of alcohol or an organic solvent (ether, benzene) scrub. Stainless steel surface of the grease, oil, lubricating oil pollution, wipe with a soft cloth, later with a neutral detergent or ammonia solution or with a special detergent.
