Step by step
- Click Full screen or tap the black area on the tool above.
- Wipe your monitor, laptop, or phone screen gently with a dry microfiber cloth.
- Single taps do nothing in full screen, so wiping a touch screen will not close it.
- Double-click, double-tap, or press Esc to exit when your screen is clean.
At a glance
| Screen type | What to do | Why |
|---|---|---|
| Touch screen phone or tablet | Use full-screen black mode | Single taps are ignored, so wiping does not trigger buttons or exit |
| Desktop monitor or laptop | Check at an angle in black mode | Dark background reveals dust and oily smudges that hide on bright pages |
| Heavy grime or sticky spots | Power off device first | Use a slightly dampened microfiber cloth only when the hardware is off |

Will wiping a touch screen close the black screen?
No. In full screen, single taps do nothing, so you can wipe your phone or tablet screen without closing it. Only a double tap or Esc exits.
Why is a black screen better than turning the monitor off?
A black screen gives a uniform dark surface while keeping the display easy to inspect at different angles, and you do not have to wait for devices to boot back up.
Can I use this on my phone?
Yes. The tool works in mobile browsers on both iPhone and Android—just tap the black area to go full screen and double-tap to exit.
