How to Clean a Phone Speaker Grille Safely
Visible lint calls for careful physical cleaning, not simply louder sound. Check the instructions for your phone model first: a tone cannot pull compacted debris out of a grille.
Prepare the phone
Unplug every cable, power the phone off and remove its case. Work where you can see the opening clearly. If the phone is wet, stop here and follow the manufacturer's liquid-exposure guidance instead of brushing a damp grille.
Find the correct opening
Check the model's manual if you are unsure which hole is a speaker and which is a microphone. Look for a case lip, film or protector covering the grille. Remove the obstruction before assuming there is dirt inside the phone.
Lift loose dirt gently
Use a small, clean, dry, soft-bristled brush on the outside of the opening. Sweep lightly across the surface; do not jab or force bristles inward. Wipe the exterior with a soft lint-free cloth. Stop if debris will not come away easily.
Avoid shortcuts that can damage it
Do not insert pins, metal picks or cotton swabs into the grille. Avoid compressed air, hot air, sprays, solvents and liquid in openings. Apple specifically warns against compressed air and moisture in openings; follow your own manufacturer's model-specific advice.
Retest, then decide
Once the phone is dry and powered on, play familiar audio at a comfortable volume or use our Speaker Test. If it is still muffled, the cause may be audio routing, moisture or internal damage. Do not keep scraping; ask for service if the grille is damaged or the problem persists.
What to do next
For a completely silent speaker, use the no-sound checklist first. For recent moisture, read the water guide and the device maker's drying instructions before charging. Use a listening test after any cleaning to compare the result.
