How to clean dust and lint out of a phone speaker

Restore a muffled speaker without damaging it: what to use, what to avoid, and how a sweeping tone helps shake loose what a brush cannot reach.

Phone speakers lose volume slowly. Months of pockets and bags leave lint and dust packed into the grille, and one day calls on speaker sound distant and music sounds flat. The fix is gentle: a sweeping tone to shake loose what it can, and a soft brush for the rest. It takes a few minutes and nothing more than you already have.

Is it the speaker or the earpiece?

Most phones have a loudspeaker at the bottom edge and an earpiece above the screen for calls. If calls are quiet with the phone at your ear but music is fine, it is the earpiece grille that needs cleaning. The same method works for both.

Step by step

Remove the case and screen protector. Take off the case and any film or screen protector, then play some audio. If it now sounds clear, the accessory was blocking the speaker.
Run the dust removal sweep. Turn the volume up, point the speaker down, and run the dust removal mode. It sweeps from 120 to 600 Hz to shake loose particles out of the grille.
Brush the grille gently. With the phone off, brush across the speaker grille with a small, clean, dry, soft-bristled brush. Hold the speaker facing down so debris falls out rather than in.
Repeat the sweep. Run the dust removal sweep once more to shift anything the brush loosened, then test the sound.

What to use, and what to avoid

Apple's own advice for a blocked iPhone speaker is a small, soft-bristled brush that is clean and dry. Consumer Reports notes that Samsung recommends the same, and its phone testers warn that sharp tools such as paper clips or tweezers can damage the mesh inside the speaker. Apple also advises against compressed air.

Safe to use

A soft toothbrush, makeup brush or small paintbrush, clean and dry
A soft, lint-free cloth for the outside of the phone
The dust removal sweep

Avoid

Pins, paper clips, needles and tweezers, which can tear the mesh
Compressed air, which can push debris further in
Liquids, including rubbing alcohol, in the openings
Pressing hard into the grille with anything

Why a sweep rather than one tone

A speaker grille is a fine mesh, and the bits of dust in it are all different sizes and weights. A single steady tone shakes everything at one rate. The dust removal mode glides from 120 to 600 Hz and back every 4 seconds, so the grille and whatever is in it get shaken at a whole range of rates in turn. Pointing the speaker down lets gravity carry loosened particles out.

It works best on loose dust. Lint that has been pressed into the mesh usually needs the brush as well — the sweep then clears what the brush has loosened.

The charging port is a separate job

The bottom speaker usually sits right next to the charging port, but cleaning the two are different tasks. Brush bristles can come loose inside a port, so the repair expert Consumer Reports spoke to suggests a small non-metal tool, such as a toothpick, for gently lifting lint out instead. Turn the phone off first, and never use anything metal near the port's pins.

Still quiet afterwards?

Check the settings. Make sure Silent mode or Do Not Disturb is not on, the volume is up, and nothing is connected over Bluetooth.
Restart the phone. Audio glitches sometimes clear on a restart.
Rule out water. If the phone has been near water recently, follow the water removal guide instead.
Listen to the sweep. The speaker test plays a sweep across every frequency. Crackling throughout points at a damaged speaker, which a repair service can replace.
