Tools, safest first
| Tool | Verdict | Why |
|---|---|---|
| Small soft non-metal brush | Recommended | What Apple describes |
| Dry cloth | Outside only | Can’t reach into the holes |
| Toothpick, pin, needle | Don’t | Can pierce the mesh or push grime deeper |
| Compressed air | Don’t | Apple says not to; it can push debris inward |
| Alcohol or cleaners | Not in the openings | Apple: no bleach or hydrogen peroxide, never submerge |
Brushing it out
Apple’s troubleshooting page says to gently brush debris from the speaker openings with a small, soft-bristled, non-metallic brush, after unplugging cables and turning the phone off. A new soft toothbrush or makeup brush works. Brush across the openings in one direction rather than pressing into them.
- Tilt the phone speaker-down so loosened dust falls out.
- Check that a case or screen protector isn’t covering the openings.
Vibrate it loose first
Shaking the membrane before you brush loosens stuck dust, so you need less scrubbing. In the Android app SonicKit:
Pick a mode on the Dust tab
Run Full sweep (40 Hz to 18 kHz) to shake the whole grille, then finish with Fine dust (6 to 16 kHz). Deep shake is a 200 to 2000 Hz square wave for dust that clings.
Speaker down, then brush
Choose 15, 30 or 60 seconds. When it’s done, SonicKit reminds you to give the grille a light brush.
Burst shake and Ultra fine unlock forever after one ad, and 3 and 5 minute runs unlock for 24 hours after one ad. The three basic modes need no ads.
Before and after
Compare the speaker response
Run the Speaker measurement on the Measure tab before and after cleaning to see whether the high end came back. If “The high end is weak” goes away, it worked.
FAQ
How often should I clean it?
There’s no set schedule. Do it when the speaker sounds quieter, or after a trip to the beach or a dusty site.
It buzzes. Is that dust?
If it buzzes on one particular pitch during the dust sweep, the speaker may need service. See how to tell the causes apart.
