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.
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%.
💡 Point the speaker downward so gravity helps the water escape. Repeat 2–3 times if needed.
Select the type of debris clogging your speaker, then run a targeted deep clean cycle.
Dry the outside of your phone first.
Let gravity help pull the water out.
Ensure audio plays through the phone's internal speakers.
Never use earbuds. Turn volume up, but 100% isn't required.
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.
Clear trapped water from your phone in about 60 seconds. The steady 165 Hz vibration physically pushes trapped liquid out of the speaker mesh.
A steady 165 Hz tone — the sweet spot for maximum diaphragm travel — physically pushes trapped water out.
Use our deep clean mode to act as a dust remover. Sweeping low frequencies shake loose stubborn dirt, sand, and lint.
Sweeps across low frequencies (120–400 Hz) to shake loose lint, dust and stubborn droplets the single tone misses.
Act as a volume booster for muffled speakers. Clear out blockages to restore heavy sound, loud bass, and crisp audio.
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.
The audio a speaker cleaner plays is not arbitrary noise. It is a deliberately shaped waveform, and the shape matters as much as the frequency.
For a complete overview, see our full guide: Clean dust and lint from a speaker.
A pure sine wave moves the diaphragm smoothly through its full travel on every cycle, with no abrupt direction changes. White noise contains energy across the whole spectrum, most of which sits above the useful band and contributes nothing to displacement. For pumping liquid, a clean sine at the right frequency delivers more useful motion per watt than a broadband signal.
Drive a speaker past its limit and the peaks of the waveform flatten into a square. The diaphragm then spends part of each cycle held at maximum extension rather than travelling smoothly — the motion becomes less like a pump and more like a vibration. This is the technical reason maximum volume underperforms 70–80 percent, and why a distorted cleaning tone is a warning rather than a sign of power.
A fixed tone at the driver's resonant frequency produces the largest possible excursion — excellent when it matches. The difficulty is that resonant frequency varies between devices, so a fixed tone is a bet. A sweep trades peak excursion for coverage, passing through whatever the resonant point happens to be. For water, a fixed tone near 165 Hz usually suffices. For dust, a sweep is clearly better because the changing motion prevents debris settling.
The voice coil is a length of fine wire, and sustained low-frequency output at volume heats it. Heat raises its resistance, which reduces output, and on a small driver prolonged thermal stress is the one genuine risk in this whole process. Thirty to sixty second cycles with pauses keep the coil within a comfortable range while delivering all the useful work.
A clean, steady hum — not a rattle and not a buzz. If the tone sounds fuzzy or distorted at moderate volume, that is the speaker telling you something is mechanically wrong, and it is worth stopping to reassess rather than turning it up.

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