The first step: vacuuming. First suck and sweep away the dirt and dust on the surface of the LED advertising screen mask.
Step 2: Wet cleaning, pay attention not to spray the lotion directly on the screen, but spray a little cleaning liquid on the cleaning cloth, and then gently wipe in the same direction. You can also use the soft brush on the vacuum cleaner to scrub the lamp mask to clean the dirt.
The third step: drying. Use a vacuum cleaner to absorb the water marks left after wet washing to ensure that the LED advertising screen mask is clean and dust-free.
