Modern flat-screen TVs — OLED, QLED, and LCD — have delicate anti-reflective coatings that are permanently damaged by the wrong cleaning products. The right approach is simpler than most people think.
What Not to Use
- Glass cleaner (Windex) or any ammonia-based cleaner — strips anti-reflective coating
- Paper towels or tissues — micro-scratches the screen surface
- Alcohol-based cleaners (above a very dilute concentration) — damages coatings on many screens
- Spraying any liquid directly onto the screen — liquid can seep into edges and damage electronics
Dry Dust Clean (Best for Light Dust)
- Turn off the TV — it's easier to see dust and smudges on a dark screen
- Use a dry microfibre cloth — the same type used for eyeglasses or camera lenses
- Wipe gently in circular motions with very light pressure
- For edges and corners: fold the cloth to get a crisp edge and wipe carefully
For most dust and fingerprints, a dry microfibre cloth is all you need.
Damp Clean (For Fingerprints and Smudges)
- Slightly dampen a microfibre cloth with distilled water — wring it thoroughly so it's barely moist
- Wipe the screen gently in circular motions — no pressure
- Allow to air dry completely before turning the TV back on
Distilled water is preferred over tap water — minerals in tap water can leave spots when it dries on the screen.
For Stubborn Smudges
A screen cleaning solution specifically formulated for flat-screen TVs (available at electronics stores) is safe. Spray onto the cloth — never directly onto the screen — and wipe gently. Avoid any product not specifically marketed for flat screens.
Tips
- Dust the screen weekly with a dry microfibre cloth to prevent build-up
- Keep the TV remote clean — greasy hands transfer to the screen when pointing
- Store the microfibre cloth in a clean bag to keep it lint-free
- The same approach works for computer monitors, laptop screens, and tablet displays
