Cleaning the speaker mesh on Xiaomi Mi8: 5 safe methods and what not to do

Xiaomi Mi8 is the flagship of 2018, which is still in demand due to its powerful hardware and high-quality assembly. But even such reliable devices eventually have a typical problem: the speaker begins to wheez, the sound becomes muted, and the bass disappears. 90% of the time, the fault is a dust-filled speaker mesh — a small metal or plastic grille that protects the membrane from mechanical damage.

Cleaning the mesh is a procedure that you can do yourself without going to the service center, but it's important to know the nuances here: wrong actions can damage the speaker, get moisture inside the body, or even unfeel off the mesh (relevant to models with adhesive attachment). This article presents proven cleaning methods unique to the Mi8, given its design features, and a list of errors that users make.

Why is the speaker grid clogged on Xiaomi Mi8: 3 main reasons

The Mi8 speaker design includes two grids: the top (visible to the user) and the inner (protects the membrane from large particles). The first is clogged most often, but there can be problems with the second - cleaning requires disassembling the phone.

The main sources of pollution are:

• 🌫️ Dust and pile – get through the holes of the mesh when carrying the phone in your pocket or bag, especially quickly accumulates if you often put the phone screen down on soft surfaces (sofa, bed).
• 🍃 Microparticles from the street – if you talk on the phone often in the wind or in dusty conditions (construction sites, sand), the net is clogged in 2-3 months.
• 💦 Moisture and fat — sweat, rain spray, or cosmetics (cream, tonal cream) — form a sticky layer to which dust sticks. This is the most dangerous reason: moisture can penetrate the speaker and cause corrosion.

On the Mi8, the speaker mesh is located at the bottom of the body, next to the USB-Type C connector. Because of this placement, it is more likely to contact the surfaces on which the phone lies, which accelerates pollution. For example, the Mi9 speaker is shifted closer to the center, and the problem is less common.

⚠️ Attention: If the sound has not recovered after cleaning the mesh, the problem may be damage to the speaker membrane or detachment of contacts. In this case, a diagnostic in the service is required - self-repair without experience can damage the microphone or vibration motor.

Preparation for cleaning: what you need and how not to damage the phone

Before you start, make sure you have everything you need. The Xiaomi Mi8 will be suitable for standard tools, but some methods (such as ultrasonic cleaning) require special equipment.

Important: Do not use sharp objects (needles, toothpicks, knives) - they can damage the mesh or membrane of the speaker. Also avoid household vacuum cleaners: it creates too strong traction and can tear the mesh from the case.

Method 1: Dry brushing with a toothbrush is the safest way

This method is suitable for regular prevention and removal of surface dust, and its advantage is the minimum risk of damage to the phone, as it does not require disassembly or the use of liquids.

Step-by-step:

1. Turn off your phone to avoid accidentally pressing buttons.
2. Take a soft toothbrush (preferably a new one or a baby one with soft bristles) and a hard toothbrush can scratch the body.
3. Carefully brush the speaker along the holes, without pressing. Movements should be short and light.
4. For better access, tilt the phone at a 45° angle and light up with a flashlight – so you can see where more dirt has accumulated.
5. After cleaning, remove the dust residues with a dry wipe from the microfiber.

If the dust is deep inside the holes, you can use a dry cotton swab, but without fanaticism: don't try to "puncture" the mesh. For the Mi8, this method is effective in 70% of cases, unless the pollution is critical.

Method 2: Scotch cleaning – for persistent contamination

If the dust is mixed with fat or potassium deposits, a dry brush may not work, and a sticky tape (scotch, paint tape) will help, the method is based on the fact that the adhesive surface "pulls" dirt from the holes.

How to clean:

1. Cut a small piece of tape (5-7 mm wide, 2-3 cm long).
2. Apply it to the speaker grid with a sticky side down and slightly press it (don't press!).
3. Take the scotch off in a sharp move, the dirt will remain on it.
4. Repeat the procedure 3-4 times, each time using a new piece of tape.

Important: Do not use wide tape - it can catch adjacent elements of the case (for example, a microphone or a USB-Type C connector). Also avoid tape with aggressive glue (for example, construction) to avoid leaving traces on the plastic.

⚠️ Note: On some copies Mi8 If the tape slips away, don't try to fix it with your hands. You better stick it in place with a drop of glue. B-7000 (point-point).

💡

If you don't have scotch on hand, you can use the sticky side of the sticker for notes (yellow post-it), which is less aggressive and suitable for delicate cleaning.

Method 3: Purging with compressed air - for deep cleaning

Compressed air in cans (such as the Air Duster) is effective at removing dust from hard-to-reach areas, but for the Mi8, this method requires caution: too strong a jet can blow away the mesh or drive dust deeper into the speaker.

How to blow properly:

• 🎯 Keep the balloon vertically (do not tilt to avoid liquid ejection!).
• 📏 Distance from nozzle to net - 5-7 cm.
• 💨 Use short pulses (1-2 seconds) rather than prolonged blowing.
• 🔄 After purging, turn the phone down with a grid and shake slightly so that the dust falls out.

Warning: Do not use a compressor or vacuum cleaner, they create too much airflow, and avoid cans of freon (cheap analogues of Air Duster), as they can leave oily traces.

Method 4: Ultrasonic cleaning – radical but effective

This is a technique that works for highly contaminated mesh when other methods don't work, and ultrasound removes even old dirt and oxides, but requires removing the mesh from the phone, which increases the risk of damage.

Step-by-step:

1. Carefully put a plastic spatula on the mesh (like a mediator) and remove it. On the Mi8, it's attached to glue, so be careful.
2. Place the net in an ultrasonic bath with distilled water (not tap water!) Temperatures 30-40°C.
3. Set the time to 2-3 minutes. A longer cleaning can damage the mesh.
4. After the procedure, dry the mesh with a hair dryer in cold mode or leave for 12 hours at room temperature.
5. Install the mesh back using the B-7000 glue (dotted to the corners).

Important: Do not use alcohol or soap solution in an ultrasonic bath - they can damage the metal coating of the mesh. Also avoid cleaning with the speaker - the membrane is not designed to contact the liquid.

Method 5: Cleaning with alcohol - for fatty and sticky contaminants

If the mesh is covered with a greasy coating (like cream or sweat), conventional methods will not help. Here you need isopropyl alcohol (90% and above) - it dissolves fats and quickly evaporates without leaving traces.

How to clean:

1. Moisten the cotton swab in alcohol and squeeze off the excess (it should be wet, but not wet).
2. Carefully run the wand on the net, without pressing. Movements in the direction of the holes.
3. For hard-to-reach places, use a toothpick wrapped in cotton wool (not metal!).
4. Allow the alcohol to completely evaporate (5-10 minutes) before turning on the phone.

⚠️ Attention: Mi8 And there's a noise-cancellation microphone next to the speaker, and if alcohol gets into the mouth, it can cause constant noise when you make calls. To avoid that, tape the microphone before cleaning.

💡

Isopropyl alcohol is the only safe liquid for cleaning speakers. Water, acetone, vinegar or household detergents can cause corrosion or damage the mesh coating.

What not to do when cleaning the speaker Xiaomi Mi8

Even experienced users sometimes make mistakes that lead to breakdowns.-5 prohibited acts for Mi8:

• 🚫 Use needles or toothpicks -- they break through the mesh or damage the membrane. Mi8 The grid is thinner than that of newer models (for example, Mi10), and it's easier to prick.
• 🚫 Vacuuming the speaker creates reverse thrust, which can tear off the mesh or drive dust inside.
• 🚫 Clean with wet wipes - moisture penetrates under the mesh and oxidizes the contacts of the speaker.
• 🚫 Put a new mesh on a double-sided tape, it will dry out and fall off over time (B-7000, LOCTITE 401).
• 🚫 Clean the speaker on – vibration from the sound can knock the grid off the spot or drive dirt deeper.

It is also not recommended to blow the speaker with the mouth - saliva contains enzymes that can cause corrosion of metal elements.
