How to clean the speaker from dirt in the Xiaomi phone: 5 proven ways

A clogged speaker in a Xiaomi smartphone is a problem that every second user faces after 1-2 years of active use. Dust, pocket villi, sweat and small debris gradually accumulate in the grille, worsening the sound: bass becomes deaf, the volume drops by 30-50%, and in the worst cases the speaker begins to wheez or stops working. Models without IP53/IP68 certification are especially vulnerable - they do not have a protective membrane, and dirt penetrates deeper.

In this article, we will discuss how to safely clean the speaker on Xiaomi, Redmi and phones. POCO (including Mi 13 flagships, Redmi Note 12, POCO F5 We'll describe methods for all kinds of pollution, from light dust to clogged debris that blocks sound, and we'll also explain why we use a toothpick or a needle to clean speakers with a different sound. IP-certification is categorically impossible: it damages the hydrophobic coating and deprives the phone of protection from moisture.

Signs of a clogged speaker: when you need to clean

Before you start cleaning, make sure that the problem is the dirt, not a software failure or hardware breakdown.

• 🔊 The sound is quieter, especially at low frequencies (bass is missing).
• 🎵 Wheezing or crackling when playing music/calls.
• 📵 The speaker is completely silent, but the speaker (top) is working.
• 🌫 Visible accumulations of dust or villi under the grille (can be illuminated with a flashlight).

If the sound is distorted only in certain applications (for example, YouTube or TikTok), the problem is more likely to be the settings of the sound uniformity. Check the settings in Settings → Sound → Sound Quality. If distortions occur everywhere, start cleaning.

⚠️ Warning: If the speaker stops working after the phone falls or moisture gets in, cleaning won't help.

Preparing the phone: what to do before cleaning

Incorrect preparation can damage the speaker or cause moisture to enter the body.

Turn off the phone and remove it. SIM-memory-card

Check that there is no moisture on the phone (condensate, drops)

Prepare a bright flashlight to inspect the grille

Close the microphone and connectors with scotch (for models without scotch). IP-certification)

-->

For models with IP53/IP68 protection (such as the Xiaomi 13 Pro or Redmi Note 12 Pro+), no additional connector protection is required, but do not use liquids - even alcohol can damage the hydrophobic coating. If the phone has recently come into contact with water, let it dry for 24 hours before cleaning.

Pay attention to the type of speaker in your model:

Once a month

Every 3-6 months

Only when there are problems with sound

Never cleaned.-->

Method 1: Soft brush dry cleaning (for mild contaminants)

The safest method for regular prevention is to use a soft brush with natural pile (like makeup) or a toothbrush with cropped bristles, suitable for all models, including IP-certified devices.

• 🖌 Tool: brush with a pile of 5-10 mm or toothbrush (new!).
• 🔦 Lighting: Direct the flashlight at an angle of 45° grid-wise.
• 🌀 Movements: Careful circular movements clockwise.

Algorithm:

1. Turn off the phone and put it on a flat surface.
2. Bring the brush to the speaker grille and lightly swipe 10-15 times in one direction.
3. Repeat movements in a perpendicular direction (cross-cross).
4. Remove the dirt from the case with a dry napkin.

⚠️ Warning: Don't press the brush -- the villi can penetrate the speaker and make the sound worse. If the dirt doesn't get removed, move on to the next method.

💡

For best effect, use an antistatic brush - it attracts dust and villi without smearing them on the grille.

Method 2: Sticky tape or scotch (for villi and hair)

This is ideal for removing hair, threads and small debris that is stuck in the grille, even for speakers with IP68, as it does not require liquids or mechanical action.

You'll need:

• 📏 Scotch width of 1-2 cm (preferably paint or stationery).
• 🔍 Lupa (optional, for accuracy).
• 💡 Lantern (for illumination).

Step-by-step:

1. Cut off a piece of Scotch 5-7 cm long.
2. Stick it to the speaker grille with the sticky side down.
3. Take a finger and pull it off (like a bandage).
4. Repeat 3-4 times, each time using a new piece of scotch.

For hard-to-reach areas, tweezers with curved ends can be used, but only for models without IP-Don't try to pick up dirt from Xiaomi speakers 13/14 series POCO F5 — It'll break the seal.

Method 3: Vacuum cleaner or hair dryer (for deep cleaning)

To remove dust from the internal cavities of the speaker is suitable compact vacuum cleaner (for example, for a keyboard) or dryer in cold air mode. This method is effective when previous methods have not helped, but requires caution.

For the vacuum cleaner:

• 🌀 Use a narrow nozzle nozzle nozzle.
• 🔇 Set the minimum suction power.
• 📱 Keep your phone 1-2 cm away from the nozzle.

For the hair dryer:

• ❄️ Turn on the cold air mode.
• 💨 Keep the hair dryer at a distance of 10-15 cm from the speaker.
• 🔄 Blow with short pulses (2-3 seconds).

⚠️ Warning: Never use a dryer in hot air mode - this can melt the speaker's protective mesh (especially in Redmi's budget models.

The method works up to 70% for dust and up to 40% for dense contaminants, and if the sound doesn't improve after the procedure, then move on to the next method.

💡

A vacuum cleaner and a dryer are the only methods that can remove dust from the inside of a speaker without disassembling the phone, but they are useless against moisture or sticky contaminants (such as sugary drinks).

Method 4: Alcohol and cotton swabs (for sticky dirt)

If the speaker is clogged with sticky substances (for example, after spilled juice or sweat), isopropyl alcohol (concentration 70% or higher) is required. This method is not suitable for models with IP68 (Xiaomi 13/14, POCO F4 GT), as the alcohol destroys the hydrophobic coating.

Instructions:

1. Wet the cotton swab in alcohol and squeeze out the excess liquid.
2. Carefully run the speaker in one movement (do not rub!).
3. Let the phone dry for 10-15 minutes in the vertical position (dynamically down).
4. Repeat dry brushing (method 1).

For models without IP-Certification can be used distilled water instead of alcohol, but its amount should be minimal (literally 1-2 drops per stick.

Method 5: Ultrasonic cleaning (for advanced cases)

If the speaker is heavily clogged and previous methods have not worked, you can use an ultrasonic bath. IP-You're not supposed to do it yourself without any experience!

How the process works:

1. The speaker is removed from the body (requires heating of the back cover and neat disconnection of the plume).
2. It is placed in an ultrasonic bath with distilled water for 30–60 seconds.
3. Dry in a special box or hair dryer (cold air).
4. It is then re-installed with contact checks.

The cost of cleaning in the service center: 800-1500 rubles (depending on the model).

• 🔧 Damage to the plume during disassembly.
• 💧 Corrosion of contacts with improper drying.
• 🔊 Loss of leakage (for models with IP53/IP68).

⚠️ Attention: Ultrasonic cleaning will cancel the warranty on the phone. If your Xiaomi is still under warranty, contact the official service - there the speaker will be cleaned for free (provided that the clog is not your fault).

What not to do when cleaning the speaker Xiaomi

Some folk methods can permanently damage the speaker or the whole phone.

• 🚫 Needles, toothpicks, paper clips: Puncture the membrane and protective netting.
• 🚫 Water from the tap: Contains minerals that oxidize contacts.
• 🚫 Compressed air (cylinders): May damage the membrane due to high pressure.
• 🚫 Acetone, gasoline, solvents: Eating plastic and adhesive bases.
• 🚫 Cleaning the phone on: The risk of short circuits when moisture is ingested.

It is especially dangerous to use metal objects to clean speakers with IP68. For example, in Xiaomi 13 Ultra, the protective membrane is thinner than a human hair and is easy to puncture.

💡

If you accidentally damaged the speaker membrane, do not try to glue it with superglue. This will only worsen the sound. It is better to replace the speaker entirely - the cost of the part for most Xiaomi models does not exceed 500-1000 rubles.
