How to use
Hold the speaker down
Point the bottom of the phone at the floor so loose dust can fall out.
Turn the volume up
Higher volume means stronger vibrations. Remove the case first.
Run Gentle, then Deep clean
Start with Gentle. If the sound is still dull, run Deep clean once.
Brush what is left
Use a dry, soft toothbrush on the grille for dirt that sound cannot move.

Questions people ask
Can sound really clean a speaker?
Partly. The vibrations shake loose particles on the grille so they can fall out. It cannot remove dirt that is stuck or pushed inside.

Whenever the speaker sounds dull or crackly. One or two runs are enough.

Gentle for a quick clean, Pulse for stubborn lint, and Deep clean when the speaker sounds clearly muffled.
