How to clean Outdoor LED screen?

1. Luckily, the first thing that needs to be done is to have the LED module semi-finished products cleaned.

We say luckily because the manufacturer will be the one doing it and not you. What happens is when the LED module is only a semi-finished product without a shell, it has to be cleaned with special washing water.

The manufacturer will have to stain it with some washing water and then brush it to accelerate the dissolution of the rosin and the flux detachment. This will then remove dust and impurities.

2. The second step is where your part starts.

The LED electronic display should be cleaned after the installation. After installation, there will naturally be dust and impurities that will accumulate.

That’s why you need to clean the surface of the LED display with clean water to remove different types of dirt. The surface can be cleaned but you have to be extra careful. You can use a cleaning agent if you have one.

3. You need to make sure you have a steady supply or access to cleaning materials. The cleaning agent and special equipment required for outdoor LED display cleaning are as follows:

LED display cleaning solution: It protects the LED screen against dust and will not cause screen damage. It is the best choice to replace chemical cleaners.

LED display repair agent: This product has several purposes. It serves as the glazing agent that makes the LED display bright just like when it is out of the box.

At the same time, it has anti-static, dust-proof and anti-corrosion functions that will get rid of dust easily. It usually has a  PH value of 7.5, so that it won’t cause damage to the LED display screen.

Special tools: spraying machine, pneumatic brush, cleaning brush, etc.

Cleaning platform: You can either choose to build a scaffolding, steel frame or hanging basket. Aerial work vehicles can also be used.

4. Outdoor LED display cleaning steps:

Dust removal. The direction of where the dust is blown should be the same, from left to right or right to left. You can use a professional electric brush to clean dust or dirt from the surface of the display module.

Cleaning: You have to spray the special cleaning solution onto the surface of the module for preliminary cleaning.

Secondary dust removal: You need to use a professional electric brush to clean the dust off the LED display module again.

Keep in mind that the brush needs to be replaced for this cleaning. You can reuse the brushes but they must be cleaned to avoid recontamination.

Secondary cleaning: Spray the special cleaning liquid onto the surface of the module. This is done to remove the dust left by the secondary dust removal.

If there isn’t much dirt, it can be sprayed with clean water. Just make sure to maintain the direction from top to bottom or right to left.

Blow dry: If you can’t dry it naturally, the surface of the display screen needs to be blown dry. Just make sure you blow dryer isn’t very hot because it might damage the screen.

Use the sprayer to spray the special repair liquid evenly to the surface of the display.

Air drying: You can let it dry naturally if the conditions are suitable. In the case of high temperature and humidity, it can be blown dry with an air gun. Just make sure the air pressure is below 3 kg.
