After prolonged use, an advertising display’s screen inevitably collects fingerprints and dust, while its casing may appear dull. Wiping it directly with a tissue? Spraying some glass cleaner? Stop right there! These common actions can easily damage the delicate screen in no time.
Don’t worry—cleaning an advertising display isn’t that complicated. Keep the following key points in mind, and you’ll be able to handle it easily, leaving the machine sparkling and prolonging its lifespan.
Before Cleaning: Do This First—Safety First
There’s one step you absolutely cannot skip before starting:
👉 Be sure to power off the display and unplug it!
This isn’t just for your safety to prevent electric shock—it also protects the advertising display. Wiping the screen with a damp cloth while it’s powered on can easily cause a short circuit, leading to costly repairs.
Choose the Right Tools: Half the Battle
You’ll need to prepare:
Microfiber Cloths (2 are best):
The kind used for cleaning glasses or camera lenses. They are soft and lint-free, making them the perfect companion for screens. Avoid using tissues or old towels, as they can be abrasive and scratch the screen.Appropriate "Cleaning Solution":
First Choice: Specialized LCD screen cleaner.
Budget Alternative: Distilled water. Remember, don’t use tap water—the minerals in it can leave white, chalky residue when dried.
⚠️ 【Crucial Avoidance】These Should Never Be Used!
Alcohol, ammonia, glass cleaner, dish soap, and soapy water are all off-limits! They can damage the special coating on the screen’s surface, causing it to become increasingly hazy over time. This type of damage is irreversible.
Step-by-Step Cleaning: A Two-Part Process
Step 1: Handle the Screen with Care
Dry First, Then Damp:
Start by using a dry microfiber cloth to gently wipe away larger dust particles from the screen. This prevents scratches during the wiping process.Spray the Cloth, Not the Screen:
Spray the cleaning solution onto the microfiber cloth until it’s slightly damp—never directly onto the screen. If liquid seeps into the edges of the screen, the machine could be damaged.Gentle Wiping:
Use the damp cloth to wipe the screen in a single direction—top to bottom or left to right. Avoid wiping in circles. For stubborn stains, apply a bit more pressure, but never use your nails to scrub.Dry Thoroughly:
Immediately use the second dry microfiber cloth to wipe away any remaining moisture until the screen is completely dry and clear.
Step 2: Clean the Casing and Vents
The casing (whether metal or plastic) is less delicate. You can use a slightly damp cloth (with water or a diluted neutral cleaner) to wipe it down.
Pay special attention to the ventilation vents, as they tend to accumulate dust. Use a soft-bristled brush (such as an old makeup brush) to gently sweep away the dust, ensuring the machine stays cool and performs optimally for longer.
Develop Good Habits: How Often Should You Clean?
High-traffic areas (e.g., malls, restaurants):
Wipe the screen lightly 1–2 times a week.Low-traffic areas (e.g., offices, exhibition halls):
Clean thoroughly every 1–2 weeks.
Daily Maintenance:
At the end of each day, use a dry cloth to wipe the screen. This significantly reduces the need for deep cleaning.
In Summary, Remember These Key Points:
Power off! Power off! Power off!
Use only microfiber cloths and screen cleaner/distilled water.
Absolutely avoid alcohol, glass cleaner, and other chemicals.
Be gentle: dry first, then damp; spray the cloth, not the screen.
By following this method, your advertising display will remain clear and crisp, effectively delivering information to your audience.
