1. First, the surface of the sheet metal enclosures needs to be rinsed with water to remove the dirt from its surface. Then add soap, liquid detergent or water with 5% ammonia solution for wiping.

2. The sheet metal enclosures are carefully rinsed with water again, and then the water stains remaining on the surface of the sheet metal enclosure are wiped dry. In the process of wiping dry, we have to wipe in the same direction in order to wipe more cleanly, and after the wiping is completed, we let the surface of the chassis and cabinet sheet metal processing dry naturally.

3. Although it is irreversible for sheet metal enclosures to get old, we can slow down this "aging" by cleaning it frequently, and keeping them in a clean state is also good for its working condition.

4. If you find that the surface of the sheet metal enclosures has lost paint, you can paint them.

The above is how to maintain the appearance of sheet metal enclosures. Sheet metal enclosures can be used in many places, and there are good and poor environments for application, so the appearance of sheet metal enclosures should mainly be cleaned.
