The maintenance methods of outdoor LED screen sheet metal cabinet mainly include the following aspects:
1. Waterproof and moisture-proof:
Keep the use environment dry and avoid anything with moisture properties from entering the LED display cabinet.

2. Dustproof Cleaning:
It is easy to be dirty when exposed to wind, sun, and dust in the outdoor environment for a long time, and it needs to be cleaned regularly to prevent dust from wrapping the surface for a long time and affecting the viewing effect.
When cleaning, the power supply should be disconnected and the surface of the screen should be wiped with a soft, fiber-free cloth. If the stain is difficult to remove, it can be cleaned with a mild detergent. But be careful not to wipe the screen with an overly wet cloth to avoid moisture seeping into the inside of the screen and causing damage.
The composition of the cleaning solution generally includes electrolyte, high-purity distilled water, antistatic liquid, etc., which can effectively clean dust and other stains on the LED screen.
