Quick answer: Turn the monitor off, dust the screen with a dry microfiber cloth in light straight passes, then wipe with a microfiber barely dampened with distilled water for fingerprints, and finish dry. Never spray anything directly at the screen, never use window cleaner, alcohol or paper towels: they scratch and strip the panel coating.
Step 1 – Power off and dust dry
A black screen shows every smudge, and an unpowered panel is safer to touch. Sweep a clean dry microfiber in straight lines, top to bottom, with almost no pressure. This removes the dust layer that would otherwise be dragged around as micro-scratches in the wet step.

An ammonia-free spray with the right microfiber cloth cleans your panel without risking the coating.
Step 2 – Damp wipe for fingerprints
Dampen a second microfiber with distilled water (tap water leaves mineral streaks) and wring it until it barely feels wet. Wipe in overlapping straight passes rather than circles, with gentle pressure. For oily spots, breathe on the area first or use the vinegar mix from the FAQ, applied to the cloth.
Step 3 – Dry finish
Follow immediately with the dry cloth in the same straight pattern. Check at an angle against the light: any remaining haze means the cloth was too wet or too dirty. Edges and corners collect drips, give them a final pass.
The never list
- Window cleaner, ammonia, bleach: destroys anti-glare coatings permanently.
- Paper towels and tissues: wood fibers, fine scratches, lint everywhere.
- Spraying the screen directly: liquid wicks into the bezel and kills backlights.
- Pressing hard: LCD panels bruise, and the marks can be permanent.
- High-percentage alcohol on coated panels: safe on some glossy glass laptops, risky on matte monitor coatings, skip it.
Keep it cleaner between wipes
Dust with the dry microfiber weekly and the wet routine becomes a monthly two-minute job. A monitor arm helps too, lifting the panel away from desk dust: see the best monitor arms. And if cleaning reveals dead pixels or a tired panel underneath the grime, our best 27-inch 1440p monitors and budget 27-inch monitors guides cover worthy replacements, with calibration steps in our monitor calibration guide.
Frequently asked questions
Can I use Windex or glass cleaner on my monitor?
No. Household glass cleaners contain ammonia and alcohol that strip the anti-glare and anti-reflective coatings on modern panels, leaving permanent cloudy patches. Monitors are not glass windows: the surface is a coated plastic film that needs plain distilled water or a screen-specific cleaner.
What is safe to clean stubborn spots with?
For grease and fingerprints that water will not lift, use a 50/50 mix of distilled water and white vinegar, or a commercial screen cleaner, applied to the cloth and never sprayed on the screen. Gentle repeated passes beat pressure: pressing hard can permanently bruise LCD pixels.
Why does my screen streak after cleaning?
Three causes: too much liquid on the cloth, tap water minerals drying on the surface, or a dirty cloth redistributing oil. Use distilled water only, wring the cloth nearly dry, finish with a dry microfiber in straight overlapping passes, and wash your microfibers regularly without fabric softener.
Power off, dry microfiber, barely damp with distilled water, dry finish. Two minutes, zero risk, and the panel coating lives as long as the monitor.
