The brass coating of brass coated stainless steel doors may fade due to oxidation or environmental factors. Here are some methods to extend the service life of brass plating:

1. Cleaning and maintenance

-Regularly remove dust with a soft dry cloth to avoid dust accumulation and oxidation.

-When cleaning, use warm water and neutral cleaning agents, and avoid using acidic or alkaline chemicals to prevent corrosion of the coating.

2. Anti oxidation treatment

-Apply anti oxidant or copper wax on the surface of brass plating to form a protective film to prevent oxidation and corrosion.

-Regularly perform passivation treatment to enhance the corrosion resistance of the coating.

3. Environmental control

-Avoid long-term exposure of brass plating to humid or high salinity environments to prevent accelerated oxidation.

-Keep dry during storage and avoid contact with sulfur-containing materials such as rubber and PVC.

4. Regular maintenance

-Regularly inspect the brass plating for any damage or signs of oxidation, and promptly repair it.

-If there is slight oxidation on the coating, copper polishing agent can be used for polishing treatment to restore luster.

Through the above methods, the service life of brass plating can be effectively extended, maintaining its bright appearance and functionality.
