Tip: press F to lock the screen in cleaning mode · Esc unlocks
Your laptop screen is covered in fingerprints, dust motes, and that one mysterious spot that's been there since last Tuesday. You grab a microfiber cloth and start wiping — but every swipe registers as a click, selecting random text, minimizing windows, or worse, launching the default music player at full volume. This tool locks your screen to a solid white or black fill and blocks all clicks, taps, and key presses so you can wipe freely. A clear on-screen message tells you it's safe to clean. Tap the message or press Esc to unlock. Enable the auto-unlock timer if you're worried about leaving it locked — it'll release the screen after 30, 60, or 120 seconds. No app installation, no system permissions, works in every browser.
When you wipe a powered-on touchscreen or keyboard, even light pressure can register as clicks, taps, or random keystrokes — potentially closing apps, sending messages, or deleting things. An input-locked screen prevents all accidental input while you clean.
White reveals dust, smudges, and fingerprints most clearly. Black helps you see streaks and oily residue on glossy screens. Many people start with white to spot every speck, then switch to black to check for streaks.
Enable the auto-unlock timer (30s, 1m, or 2m) and the screen will automatically return to normal after that time. You can also press Esc at any point.
