How to clean the speaker on Xiaomi Redmi 8 at home: from dust, dirt and moisture

Speakers in Xiaomi Redmi 8 over time lose volume or start wheezing — a sure sign of the accumulation of dust, moisture or small debris inside the grille. Especially vulnerable bottom speaker, which is more in contact with surfaces (tables, pockets) and prone to sweat or drops of water. the upper speaker (talk) suffers less, but can also get clogged with dust due to the close position to the ear during calls.

Many users are afraid to clean the speakers themselves for fear of damaging the membrane or contacts. However, 90% of contaminants can be eliminated without disassembling the phone - enough of the right tools and equipment. In this article, we will discuss 5 proven cleaning methods that do not require special skills, and also tell you how to avoid typical errors leading to breakage.

⚠️ Important: If the sound has not recovered after cleaning or there is a crack, this may indicate damage to the speaker membrane due to corrosion (for example, after ingress of liquid), in this case, you will need to replace the module in the service center.

The reasons for the pollution of the speakers in Redmi 8

Redmi 8 speakers are protected by a metal grid, but its cells are protected by a metal grid (~0.1 mm) not able to completely block microparticles, the main sources of pollution:

• 🌫️ Dust and pile – get from the air, pockets of clothes or bags, especially actively accumulate if the phone is often lying on soft surfaces (sofa, bed).
• 💧 Moisture and sweat - condensate from sudden temperature changes (for example, when you go from frost to a warm room) or sweat during conversations settle on the membrane, attracting dust.
• 🍟 Fat and crumbs are leftovers from food when you use your phone while you're eating. Fat deposits solidify and block sound waves.
• 🏖️ Sand and small debris — they get on the beach, picnic or repair work.

Symptoms of pollution appear gradually:

1. Lower volume (especially at low frequencies – basses are quieter)
2. Wheezing or crackling when playing music/calls.
3. Distortion of sound (for example, the voice of the interlocutor is heard from a barrel).
4. Complete absence of sound in one of the speakers (most often the lower one).

⚠️ Note: If the sound disappeared abruptly and is accompanied by an error "Dynamic is not connected" in the settings, the problem may be in the disconnected plume or damage to the contacts - here cleaning will not help.

What can you clean the speakers Redmi 8: safe tools

Not all tools are suitable for cleaning speakers.

• Cotton swabs (the fibers remain inside, making the situation worse).
• Toothpicks or needles (risk of puncture of the membrane).
• Wet wipes or alcohol (can damage the glue of the mesh).
• Vacuum cleaner (too strong traction can tear off the membrane).

Safe alternatives:

💡 Tip: If there are no special tools at hand, take a new toothbrush with soft bristles and trim the pile to 3-4 mm - this will reduce the risk of damage to the mesh.

💡

Turn off your phone before cleaning and take it out. SIM-Card/memory card: Vibration from incoming messages can throw you off your rhythm and lead to sloppy movements.

Step-by-step: how to clean the speaker Redmi 8 indiscriminately

Let’s start with the safest methods that do not require deep penetration into the body.

Method 1: Scotch or sticky tape

Suitable for removing surface dust and pile.

1. Cut a strip of tape 5-7 mm wide (size speaker).
2. Carefully press the sticky side against the grille without pressing.
3. Remove the tape with a sharp movement (parallel to the screen).
4. Repeat 3-4 times, using a new piece each time.

⚠️ Note: Do not use Scotch if there are greasy spots on the grid - the glue can "impress" them deeper.

Method 2: Toothbrush + compressed

Effective for deep cleaning of dust and crumbs.

Turn off the phone and remove the cards

Close the microphone (for example, with a piece of paper)

Prepare a bright flashlight for lighting

Place your phone on a flat surface-->

1. Keep the compressed air cylinder vertically at a distance of 3-5 cm from the speaker.
2. With short presses (1-2 seconds) blow out the dust. Don't flip the balloon - liquid can leak out!
3. With a soft toothbrush, walk along the grille in the direction of the cells (usually they are located vertically).
4. Repeat paragraphs 1-2 to remove the remaining dust.

🔍 Note: If the sound is quieter after cleaning, some of the dust has penetrated deeper, and the isopropyl alcohol method will help (see below).

Method 3: Cleaning with alcohol (for fatty contaminants)

Use only if greasy spots or sticky residues are visible on the grille.

1. Wet the cotton-coated disc with isopropyl alcohol (70% or higher).
2. Press the excess liquid – the disc should be wet, but not wet.
3. Gently wipe the speaker grille without pressing, moving from center to edges.
4. Let the phone dry for 10-15 minutes before turning on.

⚠️ Warning: Don’t use ethyl alcohol or vodka – they leave a film that attracts dust.

💡

Compressed air and alcohol are the only means that can clean the speaker from the inside without disassembling the phone. All other methods remove only surface contaminants.

How to Clean Redmi 8 Lower Speaker (Most Problematic)

Redmi 8's lower speaker is located next to the connector USB-C and often gets hammered because:

• 📱 Contact with surfaces (table, pocket).
• 💦 Sweat or water drops (for example, if the phone was lying next to the cup).
• 🔌 Garbage from the charging connector (dust and pile “migrate” to the speaker).

To clean it, combine methods:

1. Step 1: Blow the connector USB-C compressed air – this will remove debris that can get into the speaker.
2. Step 2: Close the connector with tape so that dust doesn’t fly in when cleaning.
3. Step 3: Use a silicone brush to dry cleaning the grille (movement from top to bottom).
4. Step 4: Complete with compressed air by holding the balloon at an angle of 45°.

📌 If the low frequencies haven't recovered after cleaning, check the sound settings:

1. Go to Settings → Sound → Sound quality.
2. Turn off the option "Adaptive sound" - it can automatically reduce the volume of the bass.
3. Turn on the bass amplifier (if available).

Cleaning Upper (Conversational) Dynamics

Redmi 8’s top speaker is less likely to be contaminated, but can get clogged:

• 👂 Ear gray (if you press the phone to your ear too tightly).
• 💄 Cosmetics (powder, tonal cream).
• 🌫️ Dust from the hair (if you carry a phone near your head).

Features of cleaning:

1. Use a thin silicone brush - it is less likely to damage the small mesh.
2. Do not apply compressed air at right angles - the jet can damage the microphone located nearby.
3. If the sulfur is deep, moisten the cotton swab in alcohol, squeeze dry and gently wet the grille (do not rub!).

⚠️ Attention: If after cleaning, the person complains that he or she can't hear you well, check the microphone - you may have accidentally touched him or her with a brush.

What not to do when cleaning the speakers

Mistakes that lead to failure:

• 🚫 Wetting the speaker with water or soap solution - corrosion of contacts is guaranteed.
• 🚫 Use sharp objects (needles, toothpicks) - a puncture of the membrane is not subject to repair.
• 🚫 Cleaning a phone on – vibration from calls can move dust deeper.
• 🚫 Blow with your mouth – saliva contains enzymes that corrode the metal mesh.
• 🚫 Use harsh chemicals (acetone, gasoline) – they dissolve glue and plastic.

🔧 If the speaker stops working after cleaning:

1. Check if the phone is unplugged (the phone will need to be broken).
2. Make sure the grid is not deformed (look under the magnifying glass).
3. Reset the sound settings: Settings → System system → Resetting settings → Resetting the sound settings.

How to protect Redmi 8 speakers from pollution

Reduce the frequency of cleanings with simple measures:

• 📱 Use a case with speaker protection (for example, with raised edges).
• 🚿 Avoid wet spaces (bathroom, kitchen during cooking).
• 🌬️ Blow the connector regularly USB-C — The garbage from there often migrates to the dynamics.
• 🎧 Connect headphones in dusty conditions (construction, cleaning).
• 🔄 Clean the speakers every 3-4 months (even if there are no visible problems).

💡 Traveler’s Tip: If you take Redmi 8 to the beach, wrap it in a thin plastic bag (with screen access) – it will protect against sand and splash.
