How to clean a TV screen without scratching it
About 5 minutes to read. Published . By the House & Hedge team.
A TV screen is one of the most delicate surfaces in the house. Its panel is thin and easily marked, and its coating is designed to reduce glare, which can be damaged by the wrong cleaner. Dust settles on the surface quickly, especially in a room with a lot of traffic or a fan running, and it shows as a gray haze in the light. A simple, dry-first routine keeps the screen clear and avoids the damage that most people do when they reach for a household spray.
Turn the TV off and let it cool before you clean it. A screen that is still warm can show streaks more easily, and the static from a dry cloth can attract dust back.
What you need
- A dry microfiber cloth, soft and lint-free
- Distilled water, for a lightly dampened cloth
- A soft brush or a vacuum with a brush attachment, for the back and the vents
- A cotton swab, for the edges and the buttons on the remote
- The maker’s cleaning instructions, if you have them
Dusting the screen
Dusting is the regular task, and it takes less than a minute.
- Turn the TV off and let it cool.
- Wipe the screen with a dry microfiber cloth in gentle, overlapping strokes. Work from the top to the bottom, and fold the cloth to a clean side as you go.
- Dust the frame and the edges of the screen with the same cloth.
A dry cloth is enough for most dust. Do not press hard, and do not rub in small circles, because that can mark the coating.
Cleaning fingerprints and smears
For marks that the dry cloth does not lift, dampen a fresh microfiber cloth with distilled water. Wring it out until it is barely damp, then wipe the screen gently in the same way. Follow with a dry cloth to buff the surface.
Never spray any liquid onto the screen, because it can run down the edges and seep behind the panel. Dampen the cloth, not the screen.
What to keep off the screen
Household cleaners contain chemicals that can damage the anti-glare coating, and they can cause permanent marks on the panel.
- Glass cleaners and window sprays. Many contain ammonia, which can strip the coating.
- Alcohol. Some screens can be marked by alcohol, and some makers forbid it altogether. Check the maker’s instructions first.
- Paper towels, tissues and kitchen cloths. These scratch the surface and can leave lint.
- Abrasive powders and scouring pads. These scratch the panel.
- Anything with a strong solvent in it. Solvents can dissolve the coating.
If you are not sure what a screen can take, use distilled water on a cloth and nothing else. Distilled water leaves no residue, and it is the safest choice for most screens.
OLED and QLED screens
OLED screens have a different surface from standard LCD panels. Their coatings can be more sensitive, and the makers often give stricter advice. Some specify only a dry cloth, and others allow a damp cloth with distilled water. Check the instructions for your model before cleaning, and do not use any product that the maker does not name.
QLED and LCD panels with a special anti-glare coating follow the same rules. The safest routine is a dry cloth, with distilled water only when needed.
Cleaning the frame, the back and the vents
The frame and the back of the TV collect dust, and the vents draw dust into the fan. Clean the frame with a damp cloth, then dry it. Use a soft brush or the brush attachment of a vacuum on the back and the sides, going over the vents to lift the dust. Keep the vent area clear, because blocked vents make the TV run hot and can shorten its life.
Do not let water reach the back of the TV or the vents, and do not spray anything near them.
The remote
Remotes collect grease and sweat on the buttons. Wipe the body with a cloth dampened in water, and use a cotton swab on the gaps around the buttons, using a very small amount of water. Dry the remote before you put the batteries back in, and do not let liquid reach the battery compartment.
Wall-mounted and stand-mounted TVs
A wall-mounted TV is cleaned the same way as one on a stand, but it needs more care around the bracket and the cables. Switch the TV off and let it cool. Do not lean on the mount or pull the TV out to reach the back, because a strained bracket can drop the set. Dust the top of the frame and the space behind the TV with a soft brush, standing on a stable step stool rather than stretching across furniture.
A TV on a stand needs its base cleaned too. Dust the stand, the feet and the shelf, and wipe any sticky spot with a damp cloth. Look behind the TV for cables that have collected dust, and wipe them with a dry cloth. Keep the cables loose enough that the TV can be moved without strain, and keep the vents clear of cables and cloth.
Glare, light and seeing the dust
Dust shows most in a bright room, especially when the TV is off and sunlight or a lamp hits the screen at an angle. Check the screen in both bright and dim light before you decide it is clean. A cloth that looks clean under a lamp can still leave a smear, and a smear can look like dust when the sun is low.
Dust on the screen is also a sign that the room needs attention. Clean the curtains, the blinds and the tops of shelves near the TV. Dust that comes off a fabric or a shelf lands on the screen again within days if the source is not cleaned.
Soundbars and speakers
A soundbar and its speakers collect dust in the grilles, and the dust can muffle the sound. Use a soft, dry brush to sweep the grille in one direction. A short burst of compressed air, held a short distance away, clears the deeper gaps. Never spray liquid into the grille. If a soundbar has a fabric front, vacuum it on a low setting with the brush attachment, and keep the nozzle a short distance from the fabric so it is not pulled loose.
Keeping the screen clean
- Dust the screen weekly with a dry microfiber cloth.
- Clean the fingerprints off the screen whenever they appear, while they are fresh.
- Keep the TV away from direct sun, which can fade the panel and make dust more visible.
- Keep candles and open flames well away from the TV.
- Check the screen for dark spots, lines or patches that look like damage, and call a repair service if you see them.
When to call a repair service
If liquid has reached the inside of the TV, switch it off at the wall and do not turn it on again until a technician has checked it. If the screen is cracked, if it shows lines or dark patches that do not clear when the TV warms up, or if a coating has been damaged by a cleaner, a repair technician can tell you whether the panel can be repaired or needs replacing.
