The harmful components in the exhaust gas can also cause the stainless steel plate to rust. Construction sites and traffic vehicles are booming. The surface of stainless steel is easily contaminated by exhaust gas, and sometimes small spots appear on the surface. This is mainly caused by harmful components, such as sulfur contained in exhaust gas from automobiles, air conditioners or factories. First of all, when the pollution level is not great, it can be completely cleaned directly with a neutral detergent or soapy water.
However, in severe cases, the cleaning method should be the same as the previous method. Usually stainless steel in this environment is cleaned 2-3 times full-time regularly every year, and cleaned regularly at least once. Corrosion of stainless steel plates caused by salt adhesion. Stainless steel in coastal areas is easily attacked by sea breeze, while 304 stainless steel will produce red rust in a short period of time.
And the rust rate in these areas is faster, and the treatment method is the same as the previous paragraph 1. Therefore, when using stainless steel exterior walls in coastal areas, use 316 stainless steel with higher corrosion resistance. If you use 304 stainless steel for exterior decoration, please try to perform regular cleaning 3-4 times a year. If the rust caused by the attached cleaning solution cannot be removed with a neutral cleaning agent, the cleaning solution should be used to remove it.
Rust caused by hand stains or fingerprints. Generally, sponges, cloths, etc., and organic solvents such as alcohol are used. If it is not completely removed, please use a special stainless steel cleaner to remove it. However, it should be noted that after cleaning with the cleaning method, it is necessary to rinse with water again. Rust caused by the surface protective film of the stainless steel plate is usually used with a sponge with a water-soluble neutral detergent or alcohol.
