Frequently asked questions
Everything about cleaning and fixing your speaker.
Yes. It uses a low-intensity pulsed tone to vibrate water and dust out — no heat, no physical contact. Keep volume at 100% and stop if you hear distortion.
60 seconds per mode is the sweet spot. Run up to 3 rounds for heavy water exposure, with 30-second breaks between rounds.
No. The cleaner runs entirely in your browser using the Web Audio API and even works offline once loaded.
Rice absorbs moisture from the air around the phone, not water trapped behind the speaker membrane. Sound-wave vibration physically ejects it instead.
If the cause is blockage or a stuck audio route, often yes. If the speaker is hardware-dead (no sound after cleaning + restart), it needs a technician.
Yes — the same physics applies. Disconnect other audio outputs first so the sound plays through the right speaker.
Use the Ear Speaker mode — a gentler program designed for the smaller call speaker. Never hold the phone to your ear while it plays.
If you have tinnitus or sound sensitivity, keep volume moderate and avoid high-frequency modes. Stop if you feel discomfort.
