The three absolute rules
Modern screens wear delicate anti-glare coatings that window cleaner strips permanently — the damage looks like a rainbow smear you can never wipe off. Every manufacturer’s care page agrees on the core rules.
Power off, unplug, let it cool
A dark screen shows every smudge (helpful), can’t be damaged by static taps, and a cool panel streaks less. Both Samsung and Sony put this as step one.
Dry microfiber first — and only microfiber
Gentle, wide strokes with a clean dry microfiber cloth handles dust and most fingerprints. Never paper towels, tissues or shop rags — wood fibers are harder than the coating and micro-scratch it. And barely any pressure: panels are damaged by pushing, not wiping.
Stubborn spots: dampen the cloth, never the screen
Distilled water on the cloth, wrung nearly dry — then wipe. Spraying anything directly at a TV is how liquid wicks into the bezel and kills backlights. This rule has no exceptions.
No window cleaner. Ever.
Ammonia, alcohol-based sprays, benzene, acetone and abrasive powders are all explicitly banned by the manufacturers. Windex on a TV is the single most expensive cleaning shortcut in America.
Brands genuinely disagree — check yours
Here is the nuance most articles miss: Samsung forbids alcohol entirely on its screens, while Sony explicitly permits a cloth lightly moistened with 70% isopropyl alcohol for stubborn marks. Neither brand is wrong — coatings differ. The safe universal script: distilled water handles 95% of everything; before reaching for alcohol on a stain, check your brand’s care page (or text us a photo — free). Frames, stands and remotes are less precious: a lightly damp cloth with a drop of mild soap is fine everywhere except the panel itself.

Quick answers
I already used Windex — is my TV ruined?
Once or twice, probably fine — inspect for hazy rainbow patches at an angle. The damage is cumulative, so just stop now; there is no undo for a stripped coating, but no need to panic either.
What about pre-moistened screen wipes?
Wipes sold specifically for electronics screens (alcohol- and ammonia-free) are generally safe. Lens wipes for glasses often contain alcohol — check the label against your brand's rule.
How do I clean the remote?
The remote is the germiest object in the living room: batteries out, then a cloth lightly dampened with mild soapy water or an alcohol wipe — remotes have no coating to protect. Toothpick for the button crevices.
How often should a screen be cleaned?
Dust monthly with dry microfiber; deep-clean only when smudges actually show on dark scenes. The less contact a screen sees, the longer its coating lives.
