Loosen lint, dust, and pocket fluff from speaker grilles with controllable sine tones and motor vibration.
Try it now
A user-controlled sine tone between 0 and 550 Hz that shakes lint and pocket fluff out of the speaker grille. Mirrors the Manual Clean mode from the Android app.
Before you start: unplug headphones, point your speaker toward the floor, and set your device volume to a comfortable level. This page runs the same tone the Android app uses, in your browser.

60s
Slide until you feel the strongest grille buzz — usually around 100–180 Hz. Adjust while playing; the tone updates live.
Finish with a 45-second vibration burst to dislodge stubborn lint. Same Low / Medium / Strong patterns as the app.
Speaker grilles act like lint traps. Over months, dust and pocket fibers settle into the mesh and damp the sound, making calls feel quiet and music feel flat.
Dust Removal pairs a user-controlled sine tone with a vibration mode. You pick the frequency that visibly shakes the grille, run it for up to three minutes, then optionally finish with vibration to dislodge anything left behind.
Step by step
Slide the dial between 0 and 550 Hz until you feel the strongest grille buzz — typically around 165 Hz for most phones.
Let the tone play for the full 60-second session. Stop early if you notice the dust has already cleared — you can re-run as many times as needed.
Switch to Vibrate mode at medium or strong intensity for thirty to forty-five seconds to shake stubborn particles loose.
Common questions
No. The app uses the same vibration motor that powers haptic feedback. Strong mode is well within the hardware's normal operating range.
Once a month is enough for most users. Run it more often if you carry the phone in linty pockets or work in dusty environments.
If sound persists after dust removal, run Sound Test to check for hardware issues, or try Water Eject in case humidity is the cause.
