Will stainless steel rust? 
The answer is yes, so rusty stainless steel how to deal with it?

     First of all from the reasons for rusty stainless steel. When the stainless steel surface of the passive film corrosion resistance in the weak part of the formation of pitting due to self-induced reaction, and then the formation of small holes, slowly with chloride ions close to the final formation of a highly corrosive liquid, More speed up the corrosion rate of stainless steel. There is also a reason for the corrosion of cracks between the crystal within the stainless steel, which destroyed the stainless steel surface of the passivation film. Therefore, the surface of stainless steel must always be cleaned and maintained, so as to extend its service life. However, when cleaning the surface of stainless steel should pay attention to: stainless steel surface can not scratch the phenomenon; can not use with bleach ingredients and abrasive cleaning solution, if the use of washing liquid, must be used after the end of clean water rinse.
1.When the stainless steel surface is grease, oil pollution, you can use a soft cloth to wipe clean, and then use a neutral detergent or ammonia solution cleaning.
2.When the stainless steel surface appears rainbow pattern, because too much use of detergent or oil caused by washing with warm water neutral detergent can be cleaned.
3.When the stainless steel surface is dusty or easy to go out of the dirt, you can use soap, weak detergent or ask to rinse. Trademarks on the surface of stainless steel, when washed with warm water or weak detergents, the adhesive ingredients should be rinsed with alcohol or organic solvents.
4.When the stainless steel surface rust occurs, you can use 10% nitric acid or grinding detergent cleaning, you can also use a special detergent cleaning. Therefore, if you want to keep the bright stainless steel, clean the surface, while extending its life, the above must be done!
