Mar 27, 2026Frequently asked questions
How does Speaker Cleaner work?
Speaker Cleaner plays low-frequency sound waves (165–230 Hz) that vibrate your speaker diaphragm, helping dislodge water droplets, dust, lint and debris from the grille. A cleaning cycle typically takes 30–60 seconds.
Is Speaker Cleaner safe for my phone?
Yes. The frequencies used (165–230 Hz) are within the normal operating range of every phone speaker. Speaker Cleaner has no moving parts, requires no permissions and is completely safe for daily use — both for emergency water removal and routine dust cleaning.
What phones does Speaker Cleaner work with?
Speaker Cleaner works with all phone models including iPhone, Samsung Galaxy, Google Pixel, OnePlus and other Android devices, because it uses the standard audio output that every smartphone supports.
Can it clean dust and lint, not just water?
Absolutely. Speaker Cleaner is designed for common obstructions that affect sound quality, including water, dust, lint and pocket debris. The same acoustic vibration that ejects water can also shake compacted particles loose from the speaker grille mesh.
How quickly does it work?
Most people hear an immediate improvement. A cleaning cycle takes 30–60 seconds, though heavily clogged or water-logged speakers may need two or three cycles.
Is Speaker Cleaner free?
Yes. The online speaker cleaner is completely free to use, and the companion mobile apps are free to download on the Apple App Store and Google Play Store.
