Czyszczenie Głośnika

Czyszczenie Głośnika ("speaker cleaning") is a free Polish web tool for iPhone and Android phones. It plays a tone that makes the speaker membrane vibrate and helps push water droplets or loose dust out through the speaker grille. There are four modes: Water (a pulsed 165 Hz tone for 60 seconds), Dust (a 120–1200 Hz sweep), Deep (a longer 90-second cycle) and Custom, where you pick the frequency yourself. On Android it can also use vibration. The sound is generated live in the browser, so there is nothing to install and no account to create. The site also includes a stereo speaker test, headphone and microphone tests, and short guides, for example what to do right after an iPhone falls into water. Typical uses: a muffled speaker after rain, a shower or a swim, or crackling caused by loose dust. It does not repair a damaged speaker or remove compacted dirt; damaged hardware needs a repair shop.
