Speaker Cleaner plays a precisely-tuned sound that vibrates trapped water and dust out of your speaker grille. No tools. No disassembly. No repair shop.

Water trapped in your speaker grille muffles every sound — calls, music, alarms. The good news: you don't need to disassemble anything. Sound vibrations push the water back out. Here's the four-step fix.
Wipe the speaker grille gently with a soft cloth. Don't push anything into the grille — that traps water deeper and can damage the mesh.
Hold your iPhone speaker-side down so gravity helps. Maximum volume gives the speaker enough movement to dislodge water droplets.
The app plays a calibrated 165 Hz sound wave — the exact frequency that drives the speaker diaphragm to vibrate harder than normal audio. This breaks the surface tension holding water in the grille and pushes droplets out.
Between cycles, tap the iPhone gently against your palm, speaker-side down. For heavy exposure (pool, full submersion), run the cycle two or three times.
Speaker Cleaner automates this whole process in 30 seconds.

A low-frequency sound around 165 Hz drives the speaker's diaphragm to oscillate much harder than ordinary audio does. Those rapid micro-vibrations shake the water droplets free and push them up and out of the grille. The same trick works on dust particles, only at higher frequencies.
165 Hz hits the sweet spot between two competing factors. Lower frequencies create bigger speaker movements (better for displacing water) but quieter output. Higher frequencies are louder but move the cone less. 165 Hz produces enough physical motion to break surface tension while still being audible at full volume — the same frequency the popular Apple Shortcuts "Water Eject" command uses.
30-second auto clean at the proven 165 Hz frequency. Tap once, point speaker down, done.
Higher-frequency sweeps that dislodge dust and lint particles trapped in the speaker grille over time.
Play test tones through each speaker individually to confirm both are working at full volume after cleaning.

Point speaker down. The 30-second cycle starts automatically.
Test and you're done
Use the stereo test to confirm both speakers are clear.
Even without water exposure, iPhone speakers gradually fill with dust, lint, and pocket fluff. You'll notice it as quieter calls, muffled music, or one speaker sounding weaker than the other. Speaker Cleaner's Dust Mode sweeps through a range of higher frequencies that dislodge particles from the speaker mesh — the same idea as the water mode, but tuned for dry debris.
For best results: remove your case first, run the dust sweep, then gently brush the grille with a soft, dry brush (a clean toothbrush works) and run the sweep one more time.
No. The app plays standard audio frequencies at normal volumes — the same kind your speaker produces every time you play music. There is no risk to the hardware.
Usually 20 to 60 seconds. For heavy water exposure, run the cycle 2 to 3 times and tap the phone gently against your palm between runs.
The water may be deeper inside the device, or the speaker mesh may be clogged with mineral residue (common after pool or ocean exposure). Let the phone air-dry for 24 to 48 hours and try again. If the sound does not return, visit an Apple Store.
Yes, but it only plays a single tone. Speaker Cleaner uses multiple calibrated frequencies, automatic cleaning cycles, and dust-specific modes — plus a stereo test to confirm both speakers are working after cleaning.
Speaker Cleaner is designed for your iPhone's built-in speakers. For AirPods, Apple recommends air drying and gentle brushing of the mesh.
Yes — Speaker Cleaner is free to download on the App Store, with optional premium features available via in-app purchase.
Every iPhone running a recent version of iOS — from older models up to the latest releases.
Crackling usually means water is still in contact with the speaker's diaphragm or magnet assembly. Run Speaker Cleaner, then let the phone rest for several hours before heavy use.
