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.
Laptop speakers collect dust easily. Select your laptop type and run a targeted cleaning 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 range where diaphragm travel is greatest.
Laptop audio fails for software reasons far more often than phones do, because there are more output paths and more processing layers to go wrong.
For a complete overview, see what to check on a laptop.
Windows: Settings → System → Sound → Output. macOS: System Settings → Sound → Output. A laptop routed to a forgotten Bluetooth speaker, an HDMI monitor or a docking station is the single commonest cause of "no sound" and "quiet sound". Monitors in particular claim the audio device silently when connected.
On Windows: Sound Control Panel → Speakers → Properties → Enhancements → Disable all enhancements. Bass boost, virtual surround and loudness equalisation routinely make laptop audio sound muffled or hollow. This resolves a surprising share of complaints on its own.
Same properties dialogue, Advanced tab. Try 24-bit, 48000 Hz. A mismatched default format produces distortion and thinness that closely resembles a hardware fault.
A recent driver update is a frequent trigger. Device Manager → Sound, video and game controllers → your audio device → Properties → Driver → Roll Back Driver. If that is greyed out, uninstalling and restarting forces Windows to reinstall a working driver.
Downward-firing laptop speakers sit millimetres above a desk and pull in dust continuously. Keyboard-side grilles collect crumbs and hair. Because the drivers are larger than a phone's, they reach useful excursion at lower relative volume — 60 to 70 percent is plenty for cleaning cycles.
This is genuinely different from a splashed phone. Liquid on a keyboard reaches the logic board within seconds through the key wells. Power down immediately, disconnect the charger, remove the battery if the model allows, and stand the machine in a tent shape so liquid drains away from the board. Do not run audio through it to test, and do not power it on.
Brush the grilles with a soft dry brush first. Then three or four sweep cycles at 60–70 percent. Larger drivers have lower resonance than phones, so a downward sweep beats a fixed 165 Hz tone here.
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.
No — and this matters. The sound has to travel through the blocked speaker to do anything, so any connected Bluetooth or wired device defeats the purpose entirely. Disconnect everything first.
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.
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.
Our tool is great for water and dust, but it cannot fix physically blown speakers or electrical damage.
