Cleaning the speaker grid on Xiaomi Redmi 8: a detailed guide with photos and tips

Xiaomi Redmi 8 is one of the most popular budget smartphones, but even it is not immune to the accumulation of dust and dirt in the speakers. Clogged mesh not only worsens the sound quality, but can also cause the speaker to break due to overheating or moisture. In this article, you will find step-by-step instructions for cleaning the mesh, recommendations for choosing tools and answers to frequent questions.

Many users are afraid to clean their own speakers for fear of damaging the membrane or electronics. However, with the right approach, the procedure is absolutely safe. We will discuss mechanical and chemical cleaning methods, as well as what mistakes are most common for beginners. If your Redmi 8 began to wheez, sound quieter or completely stopped playing low frequencies, this article is for you.

Why is the speaker grid clogged and what does it lead to?

The speaker grid is a protective barrier that prevents dust, villi and small debris from entering the housing, and over time, the pores of the grid become clogged, leading to:

  • πŸ”Š Deterioration of sound quality - the bass becomes weak, wheezing appears, distortions at high frequencies.
  • πŸ“‰ Lowering the volume - the sound as if "muffled" by a layer of dirt.
  • πŸ”₯ Overheating speaker - accumulated dust worsens heat sink, which can reduce the service life.
  • πŸ’§ Corrosion risk – if there is moisture in the dirt, the contacts may oxidize.

On the Xiaomi Redmi 8, the problem is compounded by the speaker being placed at the bottom of the case, where dust accumulates from pockets or bags. In addition, many users carry the phone in cases that do not always have a speaker cutout - this creates a "greenhouse effect" and accelerates pollution.

In 70% of cases, the silent speaker on the Redmi 8 is due to a clogged grid, not to a breakdown of the speaker itself. Before you carry the phone to the service, try cleaning the grid yourself - it will take no more than 15 minutes.

Preparation for cleaning: tools and safety measures

Before you start cleaning, prepare everything you need. The wrong tool can scratch the body or damage the speaker membrane, so choose accessories with caution.

What can't be done:

  • 🚫 Use metal objects (needles, knives, paper clips) – they can scratch the mesh or tear the membrane.
  • 🚫 Blow the speaker with your mouth – saliva contains acids that corrode the contacts.
  • 🚫 Apply aggressive solvents (acetone, gasoline) - they will damage plastic and glue.
  • 🚫 Clean the speaker on – vibration can drive dirt deeper.

⚠️ Note: If your Redmi 8 has signs of moisture (for example, under the grid you can see stains or corrosion), it is better to trust the cleaning center.

Mechanical cleaning of the mesh speaker: step-by-step instructions

This method is suitable for removing dry dirt, dust and villi. If the net is sticky or coated, use chemical cleaning first (described in the next section).

Step 1 Turn off the phone and remove it. SIM-map.

This will prevent the speaker from accidentally turning on during cleaning and protect the contacts from static electricity.

Step 2. Examine the grid.

Hold the phone to a bright light, so you'll see dirt piles. On Redmi 8, the speaker grid is located at the bottom of the case, right of the connector. USB-C.

Step 3. Remove the large debris.

Carefully put a toothpick on stuck villi or dirt particles, and move parallel to the grid, not perpendicularly, so as not to drive the debris inside.

Step 4, walk with the brush.

Use a soft brush (such as for mascara) and sweep dust off the net in short movements. Don't press too hard!

Step 5, use Scotch.

Cut a small piece of paint tape, press it against the net and rip it off abruptly. Repeat it 2-3 times, and it will help remove the small particles.

Step 6. Treat it with a cotton swab.

So, wet the stick a little in isopropyl alcohol and walk around the edges of the grid. Don't push the center, there's the speaker membrane!

⚠️ Warning: If the sound doesn't improve after cleaning, don't try to push the dirt inside the speaker with a toothpick. This can cause the membrane to rupture and then you'll need to replace the speaker.

Chemical cleaning: when and how to use liquids

If the speaker grid on your Xiaomi Redmi 8 is covered with sticky plaque (such as from sugary drinks or cream), mechanical cleaning will not help.

Safe solvents for speakers:

  • 🧴 Isopropyl alcohol (70-90%) - evaporates without a trace, does not leave divorces.
  • πŸ’§ Distilled water – only to remove sugar or salt (not suitable for fatty stains).
  • 🧼 Soap solution (neutral soap) - dilute with water in a ratio of 1:10.

How to clean:

  1. Wet the cotton swab in the selected solution (it should be wet, but not dripping).
  2. Take a gently walk around the grid, avoiding the center (there is a membrane!).
  3. Let the phone dry for 1-2 hours in a vertical position (dynamically down) so that moisture does not get inside.
  4. After drying, repeat the mechanical cleaning (see the previous section).

What can't be done:

  • 🚫 Pouring liquid directly onto the speaker will result in a short circuit.
  • 🚫 Use wet napkins with fragrances - they leave the film.
  • 🚫 Drying the phone with a hair dryer – hot air can deform the membrane.

πŸ’‘

If you don't have isopropyl alcohol on hand, you can use vodka (a fortress of at least 40%) which contains enough alcohol to degrease, but dries longer.

Cleaning dynamics without disassembly: alternative methods

If you don't want to take the risk of disassembling your phone, there are a few ways to clean the mesh without opening the case. They're less effective, but they're safe for beginners.

Method 1. Reverse thrust vacuum cleaner.

Some vacuum cleaners have a blow-out mode. Put a thin nozzle on the tube (for example, for furniture) and blow the speaker on the grid for a short time (1-2 seconds). Do not bring the nozzle closer than 5 cm so as not to damage the membrane.

Method 2: A compressed air canister.

These cans are used to clean keyboards and equipment. Hold the balloon vertically and in short bursts (0.5 seconds) blow the net. Don't tilt the balloon, it can cause the liquid to eject.

Method 3: Sticky strip for cleaning.

In electronics stores, special sticky tapes are sold for cleaning speakers (for example, 3M Cleaning Tape. They're safer than scotch because they don't leave glue. Press the tape against the net and remove it carefully.

Method 4: Ultrasonic bath (for experienced).

If you have an ultrasonic bath, you can only put a removable netting in it (if you can remove it carefully), use distilled water or alcohol, processing time is no more than 30 seconds.

⚠️ Attention: If the speaker starts to squeak or wheez more after purging, then the dirt particles hit the membrane.

What if the speaker sounds worse after cleaning?
If the sound deteriorated after cleaning, you probably drove the dirt inside the speaker. In this case: 1. Repeat the compressed air purge (3-4 short pulses). 2. If it didn't help, gently tap on the phone body next to the speaker (this can shake off particles from the membrane). 3. If the wheezing remains, contact the service for professional cleaning or replacement of the speaker.

How to disassemble Xiaomi Redmi 8 for deep cleaning of the speaker

If the surface methods don't work, you have to take the back cover off and clean the speaker from the inside, and this requires precision, but even a beginner can do it.

Tools required:

  • πŸ”§ Plastic mediator or spatula to open phones.
  • πŸ”© Screwdriver. T3 (speaker-mounting screw).
  • 🧲 Suction cup (to remove the lid).
  • 🧴 Thermopaste (if replacement is required).

Step-by-step:

  1. Turn off the phone and remove the tray for SIM-map.
  2. Heat the back cover with a hairdryer (temperature not higher than 60 Β° C) for 1-2 minutes - this will soften the glue.
  3. Insert a plastic mediator into the gap between the lid and the body and gently slap it. Start at the corner next to the volume button.
  4. After removing the lid, disconnect the battery plume (use a plastic spatula so as not to damage the contacts!).
  5. Unscrew the screws that fasten the speaker (usually 2-3 pieces).
  6. Carefully remove the speaker and clean it on both sides with a cotton swab dipped in alcohol.
  7. Blow the speaker with compressed air and let it dry.
  8. Put the phone back together, make sure all the plumes are tightly connected.

Video disassembly instruction:

If you’ve never taken a phone apart, we recommend watching YouTube videos first (e.g., search for β€œXiaomi Redmi 8 disassembly”). Pay attention to the location of the plumes and screws – they can vary in different versions.

πŸ’‘

When disassembling Xiaomi Redmi 8, the main thing is not to damage the battery plume. It is very fragile, and its breakage can lead to complete failure of the phone.

Prevention: How to protect the speaker from pollution

To avoid cleaning the speaker every few months, follow the following simple rules:

  • πŸ“± Use a speaker case with a cutout. Closed covers create a greenhouse effect, accelerating the accumulation of dust. Choose models with perforations at the bottom.
  • 🧹 Clean your pockets and bags regularly. Crumbs, grains of sand and pile from clothing are the main sources of pollution.
  • 🚿 Avoid moisture.Even if your Redmi 8 has splash protection, prolonged contact with water causes the mesh to corrosion.
  • πŸ”Š Don't put the phone down with the speaker, which increases the risk of dust and scratches on the grid.
  • 🎡 Listen to music at medium volume, and excessive loading on the speaker causes overheating, which speeds up the accumulation of dirt inside.

Additional accessories for protection:

  • πŸ›‘οΈ The film on the speaker is a transparent sticker that protects the mesh from dust, but does not degrade the sound.
  • πŸ”‡ Connector plug USB-C β€” prevents debris from entering the port, which is located next to the speaker.

If you are often in dusty rooms (for example, on a construction site or in a workshop), we recommend cleaning the speaker once every 1-2 months. Under normal conditions, it is enough to carry out the procedure 2-3 times a year.

Frequent Mistakes and How to Avoid Them

Even with the apparent ease of cleaning the speaker, many users make mistakes that lead to breakdowns.
