No. Rice is a poor desiccant — open moving air dries a device faster — and its starch dust migrates into the charging port, microphone holes and speaker grille, which can create a second problem on top of the first.
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.
Manually tune the exact Hz frequency for your speaker cleaning. Drag the slider to find the resonant frequency of your device.
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 range where diaphragm travel is greatest.
50,000 Hz is far outside the range where speaker water ejection works — and outside what any phone or laptop can output. This page explains the mechanism honestly and points you to the frequencies that do the job.
For a complete overview, see the full water ejection walkthrough.
50,000 Hz is not a usable frequency for clearing a speaker. It sits more than double the upper limit of human hearing and far beyond what any consumer audio device can reproduce.
The mechanism that removes water from a speaker is physical displacement — the diaphragm travels back and forth, pumping air against whatever is trapped in the cavity. That travel is largest at low frequencies and shrinks rapidly as frequency rises. By the time you reach tens of kilohertz there is essentially no displacement, so there is no force acting on the water regardless of how the tone is generated or how loud the volume is set.
There is a further practical point: a phone or laptop speaker cannot output 50 kHz. The amplifier, the digital-to-analogue converter and the driver are all built for the audible band. Playing a file labelled 50,000 Hz through one produces silence, not an inaudible cleaning tone.
Effective ejection happens between roughly 120 Hz and 400 Hz. The tool above operates in that band. Dry the outside of the device, disconnect Bluetooth, set volume around 70–80 percent, point the speaker grille downward, and run 30–60 second cycles with a wipe in between.
Low frequencies demand the largest diaphragm movement, so any physical restriction hits them hardest and hits them first. This produces a characteristic pattern: speech on calls still sounds acceptable while music has gone flat and lifeless, which is why people often notice the problem in music long before they notice it on a call. It also gives you a useful test. If bass returns after a cycle, blockage was the cause. If bass stays absent while mid-range is clean, suspect the driver suspension rather than the grille.
The force that moves a trapped droplet is not sound pressure — it is the physical travel of the diaphragm. Every cycle, the cone moves out and back, compressing the air behind whatever is sitting in the cavity. Low frequencies produce the largest travel, which is why a moderate 165 Hz tone clears water that a painfully loud 5 kHz tone will not touch. Turning the volume to maximum on a blocked speaker does not increase travel proportionally; past a point the diaphragm is already restricted by the obstruction, and the extra power turns into distortion and heat rather than motion.
A surprising share of muffled-speaker complaints are settings, not obstruction. Check that a volume limiter or parental control is not capping output, that no equaliser or audio enhancement is active, that Do Not Disturb is off, and that a stuck headphone routing flag is not sending audio to a device that is not there. Restarting clears a stuck route in seconds and costs nothing to try before you start cleaning anything.
Sound breaks the water film; gravity removes it. Running a cycle with the speaker facing up means every droplet you free has to be pushed uphill against its own weight, and most of it settles straight back. Facing the grille directly downward means each expelled droplet leaves and keeps going. Angling the device roughly 45 degrees so the grille points down and slightly outward tends to work better than holding it flat, because liquid runs off the casing rather than pooling on it.
No. Rice is a poor desiccant — open moving air dries a device faster — and its starch dust migrates into the charging port, microphone holes and speaker grille, which can create a second problem on top of the first.
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.
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.
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.
No. Around 70 to 80 percent is the practical sweet spot. Maximum volume on a restricted diaphragm produces distortion rather than more displacement, and adds avoidable stress to the driver.
Our tool is great for water and dust, but it cannot fix physically blown speakers or electrical damage.
