A white full-screen makes dust, smudges, and streaks obvious so you clean exactly where you need to. Here's the streak-free method — plus why to lock the screen first.
Dust and fingerprints are much easier to see against a bright, even background. A white full-screen turns your display into a free inspection light, showing every speck so you can clean precisely and check your work afterward.
A solid white fill gives your eye a uniform reference, so dust motes, oil smudges, and dried streaks jump out. Wiping on a dark desktop, you can easily miss spots you simply can't see.
Lock the screen to a solid white fill first — a screen-cleaning tool that blocks input prevents accidental clicks and taps while you wipe.
Use a dry microfiber cloth for dust. For smudges, slightly dampen the cloth with distilled water or a screen-safe cleaner — never spray directly onto the display, and never use paper towels.
Wipe in one direction or in slow circles, applying light pressure. Then switch the screen to black to check for streaks and oily residue you might have missed on white.
Microfiber is gentle and lint-free. Avoid paper towels, tissue, and household glass cleaners with ammonia or alcohol, which can strip the display's anti-reflective coating.
If a mark remains after cleaning and stays in the same place across colors, it's inside the panel — that could be a stuck pixel or pressure damage, not dirt. Run a dead-pixel test to check.
