Step-by-step: how to properly clean the Xiaomi Mi Smart TV at home

Why Xiaomi TV Cleaning Needs a Special Approach

Xiaomi Mi Smart TVs, with their slim bezels, glossy screens and hidden cooling systems, require delicate care.Unlike older models with matte surfaces, modern models are designed to be more sensitive. OLED- and LED-panels are sensitive to aggressive detergents, and dust in the vents can cause overheating and dimming. TV Q2 mi TV P1 have ultra-thin housings where dust accumulates more quickly due to limited space for air circulation.

Many users make a critical mistake: they use alcohol solutions or paper towels that leave micro-scratches on the anti-reflective coating. The Xiaomi Mi Smart TV screen has a special coating with a reflection factor of 1.2-1.5%, which can easily be damaged by improper cleaning - this will lead to a "rainbow effect" when viewed from an angle. In this article, we will discuss how to clean all elements of the TV without risk, including hidden areas that are not written in the standard instructions.

What you will need for safe cleaning

Before you start, prepare specialized tools. Normal water and cloth will not work here, you need materials that do not leave divorces and do not violate the factory protection of the screen.

• 🧴 Microfiber wipe (at least 300 g / m2, without pile) - for example, Xiaomi Mi Microfiber Cloth or analogues for optics.
• 💧 Distilled water (or purified through a reverse osmosis filter) – tap water contains salts that remain on the screen.
• 🧪 Special spray for TV (based on isopropyl alcohol not more than 10% + ScreenMom Premium or Karcher Display Cleaner.
• 🪛 Soft brush with natural pile (for ventilation holes) - for example, a makeup brush №10.
• 🔌 Vacuum cleaner with minimum power (up to 300 W) and narrow nozzle for electronics.
• 📦 Whipless gloves (optional, so as not to leave greasy marks from the fingers).

⚠️ Warning: Never use glass products (such as Mr. Proper) - they contain ammonia, which destroys the polarizing layer of the screen. Also avoid eyeglass wipes: their impregnation can leave a sticky film.

For models with an aluminum body (for example, Mi TV Q1E) will require an antistatic wipe, as metal attracts dust more than plastic. If you have a TV with a retractable camera (as in the Mi TV Lux Transparent Edition), prepare cotton swabs to clean the mechanism.

Screen cleaning Step-by-step: from dry cleaning to deep cleaning

Start with dry cleaning, which removes 80% of the dust without the risk of moisture. Turn off the TV and let it cool for 10-15 minutes (Xiaomi screens heat up to 40-45°C when running).

1. Walk across the screen with a dry microfiber in light circular motions, without pressing. Start at the center and move to the edges.
2. To remove old spots (for example, from your fingers), moisten the napkin with distilled water (no more than 2-3 drops) and wipe the contamination. Do not spray the liquid directly on the screen!
3. If you have any divorces, use a TV spray: apply it to a napkin (not on the screen!) and repeat the cleaning.

For deep cleaning (1 time in 3-6 months), use a two-step method:

1. Apply the spray on a napkin and treat the screen vertically (from top to bottom).
2. With the second dry napkin, walk horizontally (left to right) to remove excess moisture.

Turn off the TV and let it cool |Use only microfiber |Put the liquid on the napkin, not on the screen |Move from the center to the edges |Check no divorces at an angle-->

⚠️ Note: On Xiaomi TVs with quantum dots (Mi models) TV Q2 QD-LED) You can't use abrasives, you'll burn out your pixels. Check the markings on the back: if you have Quantum Dot, you only use water.

Cleaning the case and vents: hidden threats

Dust in the vents is the main reason for overheating and lowering the brightness of the backlight. In the models Xiaomi Mi Smart holes are located:

• Below (for models Mi TV A2, Mi TV P1) - behind the decorative grille.
• The back (Mi TV Q2, Mi TV ES) is under a plastic cover.
• The side (Mi TV Lux OLED) is behind narrow slots.

For cleaning:

1. Turn off the TV and remove the back cover (if it is removable, check the T5 or T6 mounts).
2. With a vacuum cleaner at minimum power, remove dust from the holes. Keep the nozzle at a distance of 2-3 cm so as not to damage the fan blades.
3. Clean the bars with a soft brush. For hard-to-reach areas, use a cotton swab dipped in distilled water.
4. Wipe the body with an antistatic wipe to reduce the buildup of dust.

Pay special attention to the HDMI and USB ports, which can cause signal interference, use dry toothpicks or compressed air (a canister with a pressure of no more than 3 bar).

Cleaning of internal components: when disassembly is required

If the TV starts to turn off spontaneously, make noise or lose brightness, the cause may be covered in dust on the board or radiator.

• 🛠️ You have experience with electronics (risk of damage to plumes).
• 🔧 There are suitable screwdrivers (T5, T6, PH00).
• 📄 You will save all screws in separate packages (Xiaomi Mi Smart uses screws of different lengths!).

Disassembly algorithm (for example, Mi TV P1 55)

1. Turn off the TV and take off the stand (4 M4×12 screws).
2. Carefully tuck the latches of the back cover with a plastic card (not a screwdriver!).
3. Disconnect the matrix plumes (pre-photo their location!).
4. Vacuum clean the dust from the board and radiator. Use a cotton swab with isopropyl alcohol (70%) to clean the fan.
5. Check the heat paste on the chip - if it's dry, replace it with the Arctic MX-4.

💡

If the TV doesn't turn on after disassembly, check the connection of the LVDS plume (responsible for image transmission), in 60% of cases, the problem is this one.

⚠️ Note: In models with ambient-lighting (Mi) TV Master) do not touch LED-Hand bands -- fat from the fingers shortens their lifespan. Use gloves or tweezers.

Cleaning the remote control and camera (for models with a AI-function)

Xiaomi Mi Remote is a breeding ground for bacteria: according to studies, it has 10 times more microbes than the toilet seat.

1. Remove the batteries.
2. Wash the body with salicylic alcohol (1%) or a wet wipe with antibacterial impregnation.
3. Clean the buttons with a cotton swab soaked in soapy solution (do not pour water inside!).
4. Dry the remote 24 hours before use (moisture can close contacts).

For TVs with a retractable camera (Mi TV Lux Transparent):

• 📸 Wipe the camera lens with a dry microfiber (do not use liquids!).
• 🔄 Check the pull-out mechanism: if it creaks, apply 1 drop of silicone lubricant to the guides.

If the camera becomes less focused, reset the settings through the menu: Settings → Devices and accessories → Camera → Reset.

What not to do when cleaning Xiaomi Mi Smart

Even small mistakes can lead to expensive repairs.Here's the top-5 forbidden:

• 🚫 Use paper towels or newspapers – they scratch the screen and leave the fibers behind.
• 🚫 Spray liquid directly on TV - it drains down and damages the backlight.
• 🚫 Clean the TV on – the risk of electric shock (voltage on the capacitors is maintained up to 5 minutes after switching off!).
• 🚫 Apply acetone or gasoline - they dissolve the glue that holds the layers of the screen together.
• 🚫 Vacuuming without nozzle – a powerful airflow can tear off small parts (for example, an antenna connector).

Also avoid cleaning powders (such as Pemoluks) – their particles remain in the ventilation holes and clog the filters. If a sticky substance (such as juice) hits the screen, do not rub it – first apply a wash gel (such as Vanish) to the stain for 5 minutes, then rinse with a wet wipe.

💡

The most common failure after improper cleaning is damage to the polarizing layer of the screen, which costs 30-50% of the price of the TV, and can only be replaced at the service center.
