10 Best Free Water Eject & Speaker Cleaner Apps for iPhone
Updated September 27, 2026 · written by AppHunt
A speaker cleaner plays a low tone at full volume; the speaker membrane moves and pushes droplets out of the grille. All the apps below rely on this trick. They differ in what surrounds it: ready-made programs, a way to check the result, or just a tone generator with a slider.
Unda
AppHunt partner · promo codeUnda plays a 165 Hz tone that shakes water out of the speaker grille — the same principle as Water Lock on Apple Watch — and then plays a test sound so you can hear whether it worked. There are programs for water, dust, the earpiece and headphones, plus speaker and microphone tests, a tone generator and a noise meter. No account and no ads.
Good for: A phone that got wet and now sounds muffled

Questions and answers
Do speaker cleaner apps really work?
For water in the speaker grille — usually yes: the vibration shakes droplets out, and you can hear the sound clear up. They cannot help if water got inside the phone. If the phone was submerged, let it dry and follow Apple's guidance before charging it.
Is there a water eject shortcut?
Yes — Water Eject shortcuts are shared online and play a single low tone, which is enough to clear the grille. An app adds programs for dust and the earpiece, a test sound and a choice of frequency. Water eject on iPhone: does it work?
Which frequency removes water?
Low tones work best because they move the membrane the most. Unda uses 165 Hz; Wave Clean uses tones up to 80 Hz. Apps with a slider let you pick the frequency yourself.
