Now Clean Your Speaker

Found a weak side? Clean it now, then test again and compare.

Speaker Cleaner

The same trusted cleaner, set for your phone.

Turn the volume to maximum and turn off silent mode — the cleaning sound needs full power.

Honest note: this tool cleans water and dust from the speaker opening, and it fixes most muffled or low sound. It cannot repair a broken speaker or water damage inside the phone — for that, please visit a repair shop. Never charge a wet phone.

Questions

Short answers, no confusing words.

Is this tool free?

Yes — completely free. No app to install, no sign-up, and nothing is uploaded anywhere. The sound is made inside your browser.

Will it damage my speaker?

No. The tones are inside the range phone speakers are built for, and the volume rises slowly. If any sound ever feels too harsh, press STOP — it stops at once.

How many times should I run it?

Run it once, then test with music. For water, 2–3 cycles are normal. Please do not run more than 3 cycles back-to-back — let the speaker rest a few minutes.
