Frequently 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, Google Pixel, OnePlus, and other Android devices. The app uses standard audio output that all smartphones support.
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 help shake compacted particles loose from the speaker grille mesh.
Is Speaker Cleaner free?
Yes, Speaker Cleaner is completely free to download and use. It's available on both the Apple App Store and Google Play Store at no cost.
