How to Clean Xiaomi Phone: From Screen to Connectors

Xiaomi smartphones are reliable devices, but even they require regular maintenance. Dust, dirt and fat prints not only spoil the appearance, but can also lead to breakdowns, from poor sensor performance to corrosion of contacts in the USB-C connector. In this article, we will discuss how to safely clean a Xiaomi phone at home without damaging the coating or internal components.

Xiaomi devices are characterized by the use of special coatings (like Gorilla Glass on screens or an oleophobic layer on the back), and the wrong tools or tools can damage them, and we have collected proven methods for all zones, from speakers to the camera, and we will also tell you what you can not do.

Preparation: What will be needed to clean

Before you start, gather the materials you need, and the use of inappropriate materials is one of the main causes of damage, such as alcohol-containing liquids destroying the oleophobic coating of the screen, and cotton leaves fibers in the connectors.

Here's what we really need:

• 🧴 Microfiber wipe (no pile, like for glasses) will suit the original from Xiaomi or a quality alternative.
• 💧 Distilled water or specialized liquid for electronics (e.g, WD-40 Specialist Contact Cleaner).
• 🧲 Soft brush (with natural bristles or syntepon) for speakers and connectors.
• 📱 Scotch or sticker (to remove persistent contaminants from the back panel).
• 🔦 Lighting to illuminate hard-to-reach places.

Important: Never use wet wipes for household appliances - they contain aggressive surfactants that corrode protective coatings. If there is no distilled water at hand, you can dilute medical alcohol with water in a ratio of 1: 1, but only for metal parts (for example, frames).

Screen cleaning: remove prints and dust

The screen is the most vulnerable part of the phone, and even if you have a Xiaomi 13 Ultra with Gorilla Glass Victus 2 protection, improper cleaning will result in microcracks or the oleophobic layer erased, which is responsible for slipping your finger and protecting against fat.

Step-by-step:

1. Turn off your phone to avoid accidental tapping.
2. Blow dust off the screen (you can use a can of compressed air at a distance of 10 cm).
3. Slightly moisten the microfiber wipe with distilled water (it should be barely wet, not wet!).
4. Wipe the screen with light circular movements, avoiding pressure.
5. For persistent stains, use the dry side of the wipe with little effort.

If the prints aren't removed, try a special screen spray (like Whoosh! Screen Shine). Apply it only on a napkin, not directly on your phone! For models with a curved screen (like the Xiaomi Mix Fold 3), use a narrow napkin or cotton swab dipped in water.

Use paper towels or toilet paper

Apply liquid directly to the screen

Use acetone or solvents

Clean the phone on-->

⚠️ Warning: If the screen becomes sticky after cleaning or is less responsive to touch, you have damaged the oleophobic coating, and you can only restore it in the service center by applying a new layer.

Cleaning speakers and microphones: removing dust without risk

Xiaomi speakers and microphones are often clogged with dust, causing sound to deteriorate or wheezing, especially for models with stereo speakers (such as the Redmi Note 12 Pro+), which can not be cleaned with water or alcohol, the liquid will get inside and disable the membrane.

Safe method:

• 🎵 Use a soft brush (for example, for watercolor) or a toothpick wrapped in a thin cloth.
• 🔍 Carefully run the speaker without pressing. The movements must be parallel to the holes.
• 💨 To remove dust from the inside, you can use a vacuum cleaner at a minimum power (hold the tube at a distance of 1-2 cm!).
• 📱 For persistent contaminants, Blue-Tack (plastic for cleaning) is suitable - roll the ball and roll on the grille.

If the sound hasn't recovered, check the settings: go to Settings → Sound and vibration → Sound quality and select Dynamic profile. Sometimes the problem is software constraints, not physical contamination.

Cleaning the connector USB-C slot SIM-map

The USB-C connector is one of the most problematic places in Xiaomi smartphones, and the dust, pile and oxidation of the contacts lead to poor charging or inability to connect accessories, and it is forbidden to clean it with a toothpick or metal objects, this will damage the contacts.

The correct algorithm:

1. Turn off the phone and remove the cable (if it is connected).
2. Hold the flashlight to the connector to assess the degree of contamination.
3. Use a plastic toothpick or a special shoulder blade for cleaning (such as UGREEN Cleaning Tool).
4. To remove oxidation, moisten the cotton swab in isopropyl alcohol (90%+) and gently wipe the contacts.
5. Allow the connector to dry for 10-15 minutes before connecting the cable.

For the slot SIM/MicroSD Use a dry cotton swab or compressed air. SIM-The card is poorly inserted, check if the contacts inside the slot are bent - this is a common problem after falls.

⚠️ Warning: If after cleaning the phone stopped charging, check the cable and the power supply. Perhaps the problem is in them, not the connector. For diagnostics, connect another charger or try wireless charging (if supported).

Removing dirt from the camera and flashing

The camera module is another critical area: the dust on the lenses leads to blurred photos, and pollution of the flash reduces its brightness. In models with a retractable camera (for example, Xiaomi Mi Mix 3), dirt can block the mechanism.

How to clean:

• 📸 For external lenses, use a dry microfiber wipe.
• 💡 Clean the flash with a cotton swab dipped in distilled water!
• 🔍 To remove dust from under the glass of the camera, use a vacuum cleaner at a minimum power (keep at a distance of 3-5 cm).
• 🚫 Do not use alcohol or glass cleaners – they will damage the enlightening coating of the lenses.

If you see stains or stains in the photo, check if the camera's protective glass is damaged. In Xiaomi models, it is often glued to double-sided tape, and when it falls, it can shift, in which case you will need to replace it in the service.

💡

To prevent camera contamination, use lens-protected covers (such as the original Xiaomi case with a camera cutout) to reduce dust and prevent scratches when falling.

Cleaning of the case: back panel and frame

Xiaomi’s body can be made of glass, metal or plastic – each material requires a different approach. For example, the glass rear panels (like the Xiaomi 12T Pro) are covered with an oleophobic layer that is easily damaged with abrasives.

Universal rules:

• 🧼 For glass and metal, use a wet microfiber with a drop of glass washing agent (without ammonia!).
• 📦 Plastic panels clean with a dry wipe or a slightly moist cloth with soap solution.
• 🎨 To remove resistant stains (such as paint or glue), use Blue-Tack or a special eraser for cleaning (Magic Cleaner).
• 🔋 Avoid getting moisture into the joints of the body - this can damage the glue that holds the screen.

If you have scratches on the body, you can mask them with car window polish (for example, Turtle Wax) and apply it only on the scratches, not on the entire body, so as not to damage the coating.

Cleaning of internal components: when disassembly is required

In most cases, internal cleaning is not required, but if the phone often overheats or the speakers wheez even after external cleaning, it may have accumulated dust inside.

If you're going to fight it out:

1. Use plastic mediators to open the case (metal tools will scratch the frame).
2. Turn off the battery first, it will prevent short circuits.
3. To clean your guts, use a soft brush and compressed air. Don't blow with your mouth - saliva contains acids!

After assembly, check the leakage — if the phone doesn't turn on, you may have forgotten to plug the plume or damaged it.

💡

If you are not sure about your skills, it is better to entrust the internal cleaning to professionals.The cost of service in Xiaomi service centers starts from 1,500 rubles, which is cheaper than repairing after a failed disassembly.
