The sound that clears dust, and why it differs from the water tone

Tap the button below. It plays a low‑frequency sound that vibrates the speaker and pushes trapped water and dust out of the grille. Turn your volume up to about 80%.

Frequency 165 Hz Time left 0.0 s

💡 Point the speaker downward so gravity helps the water escape. Repeat 2–3 times if needed.

Select how wet your device got, then tap Eject Water to run a customized cleaning cycle.

Preparation

Before you start

🧻

Wipe visible water

Dry the outside of your phone first.

🔽

Speaker facing down

Let gravity help pull the water out.

🎧

Disconnect Bluetooth

Ensure audio plays through the phone's internal speakers.

🔊

Volume around 70-80%

Never use earbuds. Turn volume up, but 100% isn't required.

Core Features

Fix My Speaker Functions

Our tool is designed to target the three most common speaker issues using precise acoustic frequencies. Whether your phone took a dive or just sounds muffled from pocket lint, here is how we fix it.

Hover over the cards below to see the effect
💧

Eject Water

Clear trapped water from your phone in about 60 seconds. The steady 165 Hz vibration physically pushes trapped liquid out of the speaker mesh.

Eject Water

A steady 165 Hz tone — the sweet spot for maximum diaphragm travel — physically pushes trapped water out.

🧹

Clean Dust

Use our deep clean mode to act as a dust remover. Sweeping low frequencies shake loose stubborn dirt, sand, and lint.

Deep Clean

Sweeps across low frequencies (120–400 Hz) to shake loose lint, dust and stubborn droplets the single tone misses.

🎵

Restore Volume

Act as a volume booster for muffled speakers. Clear out blockages to restore heavy sound, loud bass, and crisp audio.

Test Sound

A clean 440 Hz reference tone so you can hear whether your speaker sounds clear again after cleaning.

Perfectly safe. These are ordinary frequencies your speaker already plays during music. The tool never exceeds normal listening levels — it just concentrates the energy at the frequency that moves water best.

Water and dust are held in place by different forces, so the audio that shifts them is shaped differently. Using the water tone on dust is the commonest reason a dust problem stays put.

For a complete overview, see our full guide: Clean dust and lint from a speaker.

Two different holding forces

Water is held by surface tension — a continuous film with a threshold. Break the film and the whole thing releases at once. Dust is held by static charge and mechanical wedging, which has no threshold: each particle releases independently or not at all.

Why that changes the waveform

Against a threshold force, the best strategy is maximum displacement in one place — a fixed tone near the driver's resonant frequency. Against wedging and static, the best strategy is constant change, because any steady oscillation lets particles find a stable position within it. A sweep across roughly 120–400 Hz keeps the diaphragm's motion varying so no resting point exists.

What the sweep sounds like

A tone that rises and falls slowly rather than holding steady. If it sweeps too fast it behaves like broadband noise and loses the excursion advantage; too slow and it approximates a fixed tone for long stretches. A few seconds per traverse is the useful middle.

Static, and why humidity helps

Part of what holds dust in a grille is electrostatic attraction, which is strongest in dry air. This is why dust removal is often noticeably easier in humid conditions and stubborn in winter with heating running. You cannot do much about it directly — and adding moisture deliberately would create a worse problem — but it explains inconsistent results between attempts on different days.

Volume, again

Maximum volume is no more effective here than it is for water, and the thermal cost is higher because dust cycles run longer. Seventy to eighty percent, four or five passes, with pauses between them.

The honest limit of any sound

Sound moves loose material. It does nothing to anything bonded — oil, wax, sugar residue, or fibre that has been damp and dried in place. If several sweep cycles produce no change at all, the blockage is adhesive rather than loose, and no waveform addresses that.

FAQ

Common questions

Is removing dust different from removing water?

Yes. Water is held by surface tension and usually clears in one or two cycles. Dust is wedged mechanically and held by static, so it needs a sweeping range of frequencies and several more passes.

How long should I run it?

Thirty to sixty seconds per cycle, repeated two or three times with short pauses. Running it continuously for many minutes adds nothing once the accessible liquid is out, and only heats the voice coil.

How often should I use it?

For maintenance, roughly once a month is plenty. More often if you exercise heavily, work outdoors, or live somewhere humid or dusty. There is no benefit to daily use on a speaker that sounds fine.

Can this damage my speaker?

No. The frequencies used sit inside the range your speaker already reproduces whenever you play music, and the tool runs at moderate volume rather than maximum. The one genuine caution is earbuds: never run ejection tones into in-ear devices while you are wearing them.

It is still muffled after several tries. Now what?

Stop. If three cycles produce no improvement at all, the cause is not blockage. Check the symptoms on our guide to when a sound tool will not help, and have the device inspected rather than continuing to run cycles.

What this cannot fix

Our tool is great for water and dust, but it cannot fix physically blown speakers or electrical damage.
