4. .Stainless steel maintenance
(1) Regular cleaning and maintenance
(2) Pay attention to prevent the occurrence of the phenomenon of surface scratches
(3) Use soap, weak detergent or warm water to remove surface dust, dirt
(4) In addition to the surface of the binder with alcohol or an organic solvent (ether, benzene)
(5) Use neutral detergent or ammonia solution in addition to surface oil
(6) With 10% nitric acid or abrasive detergent in addition to the surface of the embroider caused by the dirt.

5. Stainless steel products Finishes
NO.4
The productsachieved by grinding of No.2D surface with No.150~320 grinding belt. They have better glossiness and discontinuous coarse grain, but their grain is finer than No.3. They are used in elevator decoration, kitchen installation, inside and outside decoration of buildings, electrical appliance front panel, etc.
HL
The products achieved by continuous grinding of No.2D surface with polishing abrasive belt with appropriate grain size. They have relatively long continuous grinding stripe (further divided into No.150~320), and are mainly used in building decoration and elevator decoration, etc.
BA
Cold-rolled, bright annealed and skin passed products with extremely good surface glossiness and high reflectivity, are used in building decoration, home appliance product and kitchen installation, etc.
Dull finish
The products achieved by appropriate rolling of No.2D or No.2B surface with dull roll. They have matte finish and are used in building decoration and elevator decoration.
