Hey Product Hunt 👋 I built Speaker Cleaner for one very specific and frustrating moment: your phone gets splashed, and the speaker suddenly sounds quiet or muffled. Many existing solutions ask users to install an app or present one frequency as a guaranteed fix. Speaker Cleaner takes a simpler and more transparent approach: it plays a gentle 150–190 Hz sound sweep for 30 seconds, directly in your browser. What makes it different: - No app installation or account - No microphone, file access, or audio upload - Sound is generated locally using the Web Audio API - Works in modern iPhone and Android browsers - Clear preparation, stopping, and safety guidance - Available in 10 localized versions - Completely free The tool is intentionally honest about its limits. The sound may help move small water droplets trapped near the speaker grille, but it cannot repair corrosion, damaged components, or serious internal liquid damage. I'd especially appreciate feedback on three things: 1. Is the guided 30-second process clear on mobile? 2. Does the frequency sweep improve your speaker after a light splash? 3. What diagnostic or testing step would be most useful after the cycle? Thanks for trying Speaker Cleaner — I'm looking forward to learning from the Product Hunt community.
