ScreenCleaner

How it works

Clean your screen without touching anything by accident

Screen Cleaner puts your device into a safe "cleaning mode": a pure-black, full-screen surface that ignores every tap, swipe and gesture — so you can wipe away fingerprints, dust and smudges without launching apps, sending messages, or nudging settings.

The three steps

  1. Tap “Start Cleaning.” The screen turns completely black and goes full-screen. A black background is deliberate — smudges and dust are far easier to see against pure black than against a bright interface.
  2. Wipe the screen. While cleaning mode is active, your taps and swipes do nothing. You can scrub the whole display — corners included — without opening anything or triggering shortcuts.
  3. Press and hold to exit. To leave, press and hold the “End” button for a full 3 seconds. A progress ring fills as you hold. Let go early and it resets — so a stray touch from your cleaning cloth can never end the session by accident.

Why a 3-second hold?

A single tap is too easy to trigger while wiping. A long press-and-hold is a deliberate, intentional action that a cloth dragging across the glass won’t reproduce. Three seconds is long enough to be unmistakably on purpose, but short enough that it never feels like a chore. If you release before the ring completes, the timer resets to zero.

Keeping the screen awake

Nothing is more annoying than the display dimming or sleeping halfway through a wipe. Where your browser supports it, Screen Cleaner uses the Screen Wake Lock API to keep the display on for the whole session, and releases it the moment you exit.

Full-screen, with a reliable fallback

On supported browsers, cleaning mode enters true full-screen to hide the address bar and browser chrome. On platforms that limit this (notably iOS Safari), a fixed full-viewport black overlay covers the screen instead — so input is always blocked either way. If the browser ever drops full-screen (for example, when you press Esc), one tap brings it back; cleaning mode itself is never interrupted.

Works on phones, tablets and laptops

Screen Cleaner is a website — there’s nothing to install. Open it on any touchscreen device and start cleaning. It’s especially handy for tablets, kiosk displays, and any phone that collects a day’s worth of fingerprints.
