The accumulation of dust in the speakers of the cell phone It is one of the most common problems among users. It not only affects the audio quality: it can also cause annoying vibrations, distortion and even temporary glitches in calls or music playback.
Although it may seem like a minor detail, cleaning this delicate area requires more than improvisation. Many users resort to homemade methods that circulate on social media—from blowing directly to using needles, swabs, or strong adhesive tape—but these tend to be more harmful than effective.

He speaker It is one of the most sensitive areas of the phone and handling it carelessly can break the protective mesh or introduce moisture.
That’s why electronics repair specialists, like iFixit and Pocket-Lint technicians, recommend specific techniques to protect your device without compromising its functionality. Based on these good practices, here at Tech Bit we leave you a clear and safe guide to clean your speaker without risk.
What you should and shouldn’t use
Most international brands agree: avoid wet swabs, metal clips, pins or industrial compressed air (such as that used to clean computers). Apple and Samsung recommend not bringing liquids or high-pressure air near it, as they can push dust into the acoustic module.
The ideal, according to specialists, is to work with soft, dry tools designed for electronics:
- A soft bristle brush (can be an antistatic one).
- A manual air bulb, like those used for cameras.
- Soft, low-adhesion painter’s tape or masking tape.
How to remove dust without damaging the speaker
1. Use soft air, not compressed air
Place your cell phone face down and use a manual air bulb to deliver short, controlled bursts. This removes surface dust without the risk of pushing it in.
2. Gently brush the grille
Using a dry brush with very soft bristles, use short, light strokes. Do not press: just drag the accumulated dirt. The experts at iFixit insist on not using hard or metal brushes.
3. Remove residue with low-adhesion tape
Place a small piece of soft tape over the grate and carefully remove it. This method helps lift trapped particles without tearing off the mesh or leaving residue.
4. Final cleaning: check the sound
Play an audio and check if the speaker can be heard clearly. If the distortion persists, it could be due to internalized dirt or moisture, and in that case it is recommended to consult a specialized technician.
Also, you should know that some devices like Xiaomi, Redmi and POCO have a function called “Clean speaker” which emits a powerful sound for around thirty seconds to eliminate the dust lodged in its grille.
