Today, many elevator hall doors and cars are made of mirrored stainless steel, which makes the elevator appear exceptionally bright. This mostly stainless steel is carefully made of iron-chromium alloy and other trace elements, which has good corrosion resistance. A passivation film forms on its surface, allowing it to exist in nature as a more stable oxide. However, despite its excellent corrosion resistance, stainless steel is still affected by oxidation over time, so regular maintenance is essential. 
So, how to maintain stainless steel?In addition to regularly allowing professional maintenance personnel to professionally wipe the stainless steel, we should also pay attention to the following points ourselves:
First of all, avoid using bleaching ingredients, abrasives, and tools such as steel wool balls when cleaning to avoid scratching the mirror.
Secondly, dust and dirt on the surface of stainless steel can be removed with soap, weak detergent, or warm water. For labels, films, etc., they need to be cleaned with warm water, mild detergent, or erased with alcohol or organic solvents.
In addition, contaminants such as grease and lubricating oil can be wiped clean with a soft cloth and then cleaned with a neutral detergent or ammonia solution. If rainbow streaks appear, they may be caused by overuse of detergents or oils, which can be removed with a warm neutral detergent. If rust is caused by dirt, it can be treated with nitric acid, abrasive detergents or special detergents.
As long as we follow the correct maintenance methods, we can effectively extend the service life of stainless steel and maintain its clean, bright and gorgeous appearance. In this way, not only our living environment is more beautiful, but also the value of stainless steel products has been fully reflected.
