The speaker grid on Xiaomi smartphones is not just a decorative element, but an important part of the acoustic system, which over time gets clogged with dust, villi from a pocket or bag, and sometimes even particles of cosmetics or cream, which leads to a deterioration of the sound: The bass becomes deaf, the high frequencies become muted, and in some cases the speaker begins to wheez. Especially the problem for models with a lower speaker placement (for example, the Redmi Note 12 Pro).+ or POCO X5 Pro) where the mesh is in contact with surfaces during everyday use.
Many users are afraid to clean the mesh themselves for fear of damaging the speaker membrane or impairing the tightness of the body. Indeed, careless actions can lead to loss of water protection (if any) or even failure of the acoustic module. However, with the right approach, cleaning can be done at home without disassembling the phone and contacting the service. In this article, we will discuss 5 proven methods suitable for most Xiaomi models, including flagships and budget series, and also tell you what to do absolutely not.
Why is the speaker grid clogged and what does it lead to?
The main cause of clogging is small particles of dust and debris that penetrate through microscopic holes in the grid.
- π± Pockets and bags: pile from clothes, thread, grains of sand, crumbs.
- π Cosmetics: powder, tonal cream (if the phone is in the purse next to the makeup).
- πΏ Street dust: especially relevant for active users who often take their phone outdoors.
- πΎ Animal hair: if the smartphone is lying on the sofa or carpet.
The effects of clogging are not limited to the deterioration of sound, but in advanced cases, it can lead to:
- π Overheating of the speaker due to difficult ventilation.
- π§ Corrosion of contacts (if moisture gets under the grid along with dirt).
- π« The service center unit in warranty repair if damage occurs due to improper cleaning.
On some Xiaomi models (such as the Mi 11 Ultra or Xiaomi 13 Pro), the speaker mesh is integrated into the metal case, making it difficult to clean it, and in such cases, special care is required not to scratch the coating.
What you need to clean: tools and materials
Before you start the procedure, prepare the necessary tools. Do not use improvised tools like toothpicks or needles - they can damage the mesh or membrane of the speaker.
| Tool. | Appointment | Where to buy | Cost (β) |
|---|---|---|---|
| Soft brush (with natural pile) | Removal of dust from the surface of the mesh | Artist Stores, AliExpress | 50β200 β½ |
| Microfiber wipes | Cleaning from fat spots and finger marks | Optics, electronics stores | 30β100 β½ |
| Cotton swabs (thin, without alcohol) | Cleaning hard-to-reach corners | Pharmacy, supermarket | 20β50 β½ |
| Compressed air cylinder | Dust blowing out of holes | Computer shops | 300β600 β½ |
| Isopropyl alcohol (70%) | Disinfection and removal of sticky contaminants | Pharmacy, radio shops | 100β200 β½ |
For models with waterproofing (for example, Xiaomi 12S Ultra or Redmi Note 11 Pro+ 5G) it is not recommended to use liquids - they can violate the tightness of the gaskets. In this case, limit yourself to dry methods: brush and compressed air.
β οΈ Attention: Never use WD-40, Acetone or other aggressive solvents that break down the protective coating of the mesh and can penetrate the speaker, damaging the membrane.
Method 1: Dry brush and compressed air cleaning (the safest)
This method is suitable for regular prevention and removal of surface dust and can be used every 1-2 months to prevent severe clogging.
Turn off the phone and get it out. SIM-map
Place the device on a flat surface (screen down)
Prepare a brush and a cylinder with compressed air
Wear an antistatic bracelet (optional)-->
Step-by-step:
- Turn off the phone and put it up with the speaker. If you clean the bottom speaker (like the POCO F4 GT), position the device vertically so that debris falls down.
- With a gentle brush, brush the dust off the grid with neat movements, move from center to edge without pressing.
- Take a tank of compressed air and short pulses (1-2 seconds) to blow dust out of the holes. Keep the balloon at a distance of 5-7 cm from the phone, so as not to damage the membrane by air flow.
- Repeat the procedure 2-3 times, changing the angle of inclination of the balloon.
For models with stereo speakers (such as the Xiaomi 13T Pro), repeat the cleaning for the top speaker located next to the conversational speaker.
π‘
If you don't have compressed air, you can use a vacuum cleaner at a minimum power with a narrow nozzle, and the main thing is not to touch the mesh and not to turn on the turbo mode!
Method 2: Wet cleaning with cotton swabs (for persistent contaminants)
If there are greasy spots or sticky contaminants on the grid (for example, from cream), dry cleaning will not be enough, in which case wet treatment will help, but with caution: the liquid should not penetrate the body.
Important: This method is not suitable for phones with official IP53/IP68 waterproofing (e.g. Xiaomi 12T Pro or Redmi Note 12 Pro+).
Instructions:
- Moisten the cotton swab in isopropyl alcohol (70%) or distilled water. Press the excess liquid so that the stick is barely moist.
- Carefully run the net surface without pressing. Move along the holes, not across.
- To remove contaminants from corners, use a toothpick wrapped in microfiber (not a bare toothpick!).
- After cleaning, dry the phone for at least 30 minutes in an upright position (speaker down).
β οΈ Warning: If the sound is quieter or wheezing after a wet cleaning, turn off the phone immediately and leave it to dry for 12 to 24 hours.

Method 3: Cleaning with sticky mass (for deep contaminants)
To remove deep-seated dust or fine debris (such as sand), you can use sticky mass to clean keyboards (such as Slime or analogues), a method that is more effective than compressed air, as the mass penetrates the holes and pulls out the dirt.
How to clean:
- Buy a special sticky mass (don't use regular plasticine!) It should be soft and elastic.
- Snap a small piece and roll it into a thin layer.
- Carefully press the mass against the speaker grid and remove it immediately. Repeat 2-3 times, using a new piece each time.
- Remove the residues with a dry microfiber.
This method works particularly well for models with a metal mesh (for example, Xiaomi Mix 4 or Black Shark 5 Pro), where the holes are larger than plastic counterparts.
π‘
Sticky mass removes up to 90% of contaminants from the holes of the mesh, but it can not be used more often than 1 time in 3 months - it can leave microparticles that accumulate over time.
Method 4: Ultrasonic cleaning (for power users)
This is the most effective, but also the riskiest method, and it's suitable for phones with removable speaker mesh (like some POCO models or older Redmis), if the mesh is glued or integrated into the case, this method can not be used.
What you need:
- π οΈ Ultrasonic bath (can be bought on AliExpress for 1000-2000) β½).
- π§ Distilled water or isopropyl alcohol.
- π§΄ Soap solution (non-aggressive, for example, for baby bottles).
Step-by-step:
- Carefully remove the speaker grid with a plastic mediator or guitar plectre, and some models hold it on latches, others on glue.
- Place the net in an ultrasonic bath with a warm soap solution for 1-2 minutes.
- Remove the net, wash under running water and dry for at least 6 hours.
- Set the grid back, making sure it fits tightly.
β οΈ Warning: After ultrasonic cleaning, be sure to check the water protection (if any) for this, you can use a leakproofness test at the service center or special indicator strips.
Method 5: Professional cleaning in the service (when nothing helps)
If you've tried all the methods, but the sound hasn't recovered, it's probably not the grid that's the problem, but the damage to the speaker or its contacts. In this case, you'd better go to the service center. The cost of cleaning official Xiaomi services starts at 500. β½, A replacement speaker will cost 1500-3000 β½ model-wise.
When to go to the service:
- π The sound has gone completely or has become very quiet.
- π¦ After wet cleaning, the speaker "bubblesΒ».
- π§ The net is deformed or torn off.
- π« Phone gives out "Speaker malfunction" error in equipment test (#4636##).
The service uses professional equipment, such as vacuum pumps to remove dust or ultrasonic baths with temperature control, and craftsmen can disassemble the phone and clean the speaker from the inside, which is impossible to do at home.
What not to do when cleaning the speaker Xiaomi
Some popular methods can irrevocably damage the speaker or the body of the phone, and this is strictly forbidden:
| Prohibited action | Effects of consequences |
|---|---|
| Use toothpicks, needles or pins | Puncture of the membrane speaker, scratches on the body |
| Blow the speaker with your mouth | Saliva and bacteria getting inside, corrosion of contacts |
| Clean with wet wipes with alcohol >70% | Destruction of the glue layer of the mesh, damage to plastic |
| Apply the vacuum cleaner at full capacity | Breaking of the mesh or membrane due to strong suction |
| Use an eraser for cleaning | Static electricity pulls dust back in. |
It is also not recommended to clean the speaker when on - vibration from the sound can complicate the process and lead to the entry of debris inside.
