You switch the TV off at the end of the evening and there it is in the black glass: a ghostly handprint, a pale arc where someone wiped it with a sleeve, a cloudy patch that was not there last week. The instinct is to grab the window spray and a sheet of kitchen roll. That instinct is the one thing that does lasting damage to a TV screen.
This guide starts from what you can see on the screen, works out the likely cause, and then gives fixes in order from the gentlest (a dry cloth) to the ones that need real care. Most TVs never need anything beyond the first two steps.

What is on your screen, and what it usually is
Different marks respond to different treatment, so it helps to name the problem before you reach for a cloth. Work down this table and start with the fix in the right-hand column.
| What you see | Most likely cause | Start with |
|---|---|---|
| Fine grey haze, more obvious when the screen is off | Dust, often held on by static | Dry microfibre cloth, light strokes |
| Oval smears and finger-shaped patches | Skin oils from touching the screen | Cloth very lightly dampened with water |
| Streaks that appear after you have cleaned | Too much liquid, tap water minerals, or a dirty cloth | Re-wipe with a clean, barely damp cloth, then buff dry |
| Small crusty or sticky dots | Dried splashes from cooking, drinks or sneezes, or tape residue | Soften with a damp cloth held on the spot, then wipe gently |
| White rings or cloudy spots | Hard water that dried on the surface | Distilled water on a cloth, then a dry cloth |
| Rainbow-like blotches or dark patches that stay when the TV is on | Pressure damage or a fault behind the glass | Not a cleaning problem. See the last section |
| Scratches or a dull, worn patch | A coating that has been rubbed away or a scratched surface | Cleaning will not reverse it. See the last section |
If the picture itself looks wrong (stuck bright pixels, vertical lines, a dark blotch that follows the picture), that is a panel fault rather than dirt. Wiping harder will not help and can make it worse.
Why TV screens are easier to damage than a window
A TV looks like glass but many are not. Plenty of LED and LCD sets have a soft plastic or film layer on the front, often with an anti-glare or anti-reflective finish. That finish is what scatters room light so you see the picture rather than your reflection, and it can be wiped away by abrasive cloths or the wrong chemicals. OLED and QLED sets differ in how the picture is produced, but the surface you touch needs the same careful treatment.
This is why Samsung, LG, Sony and other makers all say much the same thing in their manuals: switch off, use a soft dry cloth, and if you must use liquid, a cloth lightly dampened with water. They typically warn against sprays applied directly to the screen, alcohol, ammonia, acetone, thinners and abrasive cloths or paper towels. Always check the manual for your exact model, because it overrides anything general, including this page.
Pressure matters as much as chemistry. LCD panels are layered, and pressing on the surface can leave a lasting distortion. Wipe with the weight of your hand, not your fingers pushing.
Before you start
Switch off, unplug and let it cool
Turn the TV off at the set and pull the plug, or switch off at the wall. A set left in standby still has power running through it, and you are about to bring a damp cloth close to its edges. A dark screen also shows dust and smears far better than a lit one, so you can see what you are doing. Give it a few minutes if it has been on for hours. A warm screen dries cleaning liquid too fast and leaves streaks, and the surface should feel cool to the back of your hand before you start.
Check the manual and test on a corner
Look for the cleaning or care page in the manual, or on the manufacturer’s support site using the model number from the label on the back. Some makers name an approved screen cleaner or cloth, and some supply a cloth in the box. Whatever you plan to use, try it on a bottom corner first, then check in daylight for any dulling or marks.
What you need
- Two clean, dry microfibre cloths, one for cleaning and one for buffing. Wash them without fabric softener, which can leave an oily film.
- A small bottle of distilled water, which has no minerals to dry into white spots. Tap water is a second best if you wipe it dry straight away, but in hard water areas it leaves marks.
- Cotton buds or a soft, clean brush for the bezel and corners.
- Never paper towels, tissues, kitchen roll or old T-shirts. Paper contains fibres that can scratch coatings, and rough cloths hold grit.
Fixes, from the gentlest to the most careful
Step 1: dry dusting, which solves most screens
Fold a clean microfibre cloth into a pad and wipe in one direction, top to bottom or left to right, with almost no pressure. Lifting the cloth between strokes and turning it to a clean face stops you dragging collected grit across the glass. Do the same for the bezel and the top edge, where dust tends to gather and then falls onto the screen later.
This is where a decent cloth earns its keep. A good microfibre cloth for screens is dense and soft, hemmed rather than raw-edged, and has no scratchy label. A pack of electronics-grade microfibre cloths is enough for a TV, a laptop and a phone, and our comparison of microfibre and cotton cloths explains why the weave traps dust rather than pushing it around. If the cloths have been used on kitchen surfaces, keep them separate, because grease on the cloth ends up on the screen.
Step 2: a barely damp cloth for fingerprints and smears
If marks remain, dampen the second cloth with distilled water, then wring it until it feels only slightly cool to the touch. Never spray the screen itself, because liquid can run down behind the edge of the panel. Wipe the mark with light, even strokes (straight lines are easier to keep consistent than circles), then go straight over it with the dry cloth.
Wiping a fingerprint in tiny circles tends to spread the oil. Instead, make one slow pass through the mark and turn the cloth to a clean part for the next. Most smears are gone within two or three passes. If nothing shifts, do not scrub, move on to the next step.
Step 3: a screen-safe spray, if water is not enough
Some marks, such as old greasy fingerprints or a child’s sticky touch, are easier with a dedicated screen cleaner. Look for a product that says it is suitable for TVs and LCD, LED, OLED or QLED screens, and is free of alcohol and ammonia. Spray it onto the cloth, not the screen, and follow the instructions on the bottle. An alcohol-free screen spray suits households with sticky fingers or a glossy screen that shows every mark, and a kit with spray and cloth together saves buying the two separately. Check it against your manual first, as a handful of makers say to use water only.
A note on homemade mixes. You will see advice online to use a half and half mix of distilled water and isopropyl alcohol, or white vinegar and water. Many TV manufacturers specifically say not to use alcohol or other solvents on the screen, and anti-glare coatings can be harmed by vinegar or alcohol over time. Because the coating cannot be replaced, we suggest sticking to water or a purpose-made screen cleaner unless your manual says otherwise.
Step 4: stuck-on marks and old residue
For a dried splash or a spot of sticky residue, lay a lightly damp cloth over it for a minute so it softens, then lift it gently with a cloth wrapped around your fingertip. Do not scrape with a nail, a coin or a blade, and do not use a bank card unless the residue is on the plastic frame rather than the screen. For white hard-water spots, use distilled water on the cloth and dry the area straight away. Do not use solvent-type adhesive removers on the screen itself. On the plastic bezel, a damp cloth with a drop of washing-up liquid is fine, as long as nothing drips towards the gaps.
Step 5: the bezel, stand, vents and ports
Dust in the vents makes sets run warmer, so it is worth a quick look. Use a dry soft brush or a dry cloth around the vents and speaker grilles, and cotton buds for tight corners. A short blast from a can of compressed air can clear vents and ports. Hold the can upright and away from the glass, use short bursts, and never use it on the screen, because the cold propellant can leave marks. If you would rather not use a can, a soft brush does the same job more slowly. Keep any liquid away from vents, ports and the power socket.
Step 6: check your work properly
Wait until the screen is fully dry, which usually takes a minute or so, then look at it with the TV still off. Stand to one side so the light from a window or lamp rakes across the glass, because that angle shows streaks, lint and leftover smears that a head-on look hides. If a streak remains, do not add more liquid. Go over it once with a clean section of dry cloth. Refresh your cloth after a large screen, since a cloth that has absorbed oils will redeposit them. A second set such as soft screen-cleaning microfibre cloths is worth keeping solely for the TV, and washing them separately from towels stops lint transferring. Only plug the set back in once everything is dry, including the bezel.
Wall-mounted sets and awkward spots
A bracket-mounted TV is awkward to reach, and the temptation is to lean on the screen for balance or to stretch with a wet cloth. Do neither. Use a stable step, keep the cloth in your hand rather than pushing it with your fingertips, and clean the upper edge with a dry, soft brush so dust does not drop onto your freshly wiped screen. If the TV sits above a fireplace or in a kitchen, expect grease and soot to turn into a sticky film that needs a damp pass more often than a normal living room set.
The same job on different types of TV
| Type | What to know | Care point |
|---|---|---|
| LED or LCD (including most QLED) | Layered panel, often with a soft front film | Very light pressure, no sprays on the screen |
| OLED | Each pixel makes its own light, thin panel | Same gentle wipe, avoid pressing near the edges; follow the maker’s guidance |
| Curved or glossy screens | Show every smudge and swirl | Wipe in straight strokes and finish with a dry buff |
| Matt or anti-glare screens | Finish can burnish if rubbed | Use almost no pressure and never rub repeatedly in one spot |
| Touchscreen or interactive display | Gets handled all the time | Switch off, clean more often, and check the maker’s advice on disinfecting |
If you are unsure what you have, the model number on the back or in the settings menu will tell you the technology. For a touchscreen display used in a shared space, such as a school or office, the manufacturer’s disinfection advice should be followed rather than a household recipe.
How often, and how to keep it clean for longer
A TV does not need cleaning on a schedule so much as when you can see a problem. A quick dry wipe when you dust the room is enough for most homes. Households with small children, pets that rub against the set, or a TV near the kitchen may find a light wipe every week or two is easier than a big clean after months of build-up. Over-cleaning risks wearing the surface, so there is no benefit to doing it more often than you need to.
| Household | Dry dust | Damp wipe |
|---|---|---|
| Adults only, living room | When you dust | When marks show |
| Young children | Weekly | As soon as smears show |
| Pets | Once or twice a week, as fur and dust stick to static | When marks show |
| TV near a kitchen or open window | Weekly | Monthly, plus after cooking splashes |
- Keep the remote within reach so no one is tempted to touch the screen.
- Dust the unit and shelf as well as the screen, otherwise the dust settles straight back.
- Avoid putting the TV directly opposite a radiator or heating vent, which dries the air and increases static.
- Keep food and drinks away from the set, and wipe splashes straight away rather than letting them dry.
- Use a screen cover or dust cloth only if it is clean and soft, and never lay a cover on a warm screen.
Tidy-up habits work the same way as the rest of the room. Our guide to cleaning double glazed windows and the piece on cleaning windows without streaks use similar principles of clean cloth, little liquid, and a final buff. For other kinds of glass-fronted devices, see our advice on cleaning a laptop screen safely and cleaning a screen protector. More general products are collected under cleaning products and furniture, and furniture polish and sprays should stay well away from the TV.
Remote controls are the other thing that touches the room’s germs and the screen’s smudges. Wipe the buttons with a barely damp cloth, tilt the remote so liquid does not run between the keys, and let it dry before using. It is the quickest way to cut down on fingerprints near the set.
A word on screen protectors. Add-on films or glass covers are sold for some TVs, mainly to cut glare or protect a screen in a shared space. They can trap dust or bubbles if fitted badly, they can change the look of the picture, and the maker’s guidance on whether they are suitable varies, so read the manual before buying one. If you do fit one, clean it as you would the bare screen, and replace it if the edges lift or it becomes scratched. The principles in our guide to cleaning a screen protector apply here too.
When it is not a cleaning problem
- You used the wrong product. If you have already used glass cleaner, alcohol or a solvent and the screen looks cloudy or patchy, stop cleaning it. Rinsing does not undo the damage. Contact the manufacturer or retailer, but be honest about what you used, because damage from cleaning is not usually covered by a warranty.
- Liquid got in at the edges. Unplug it, do not turn it on, and let it dry in a warm, ventilated room for at least a day. If it behaves oddly afterwards, have it checked by a qualified repairer.
- Marks stay when the TV is on. Persistent dark or bright patches, lines or pressure marks are a panel problem. Check your warranty or consumer rights.
- A crack or chip. Do not wipe it. Glass fragments or liquid crystal leaking from a broken panel should be handled by a repairer, and a cracked TV should be unplugged.
Take photos of any existing damage before you start. It is a quick step and can help if you need to talk to the retailer or manufacturer later.
Questions people ask about cleaning a TV
Can I use glass cleaner or window spray on a TV screen?
No. Most window sprays contain ammonia or alcohol, and TV makers warn against both, because they can dull or strip the anti-glare coating on the front of the screen. Once the finish is damaged it cannot be repaired. Use a dry microfibre cloth, then a cloth lightly dampened with water, or a spray made for screens.
What is the best thing to clean a TV screen with?
A clean, dry microfibre cloth is the best first choice and is enough for most dust and light marks. For fingerprints, dampen the cloth very slightly with distilled water. A screen cleaner that says it is alcohol-free and ammonia-free is the next step, sprayed onto the cloth rather than the screen.
Can I use wet wipes or screen wipes on a TV?
Only wipes that state they are suitable for LCD, LED or OLED screens, and even then check your manual. Ordinary baby wipes, antibacterial wipes and kitchen wipes can contain alcohol, fragrance or oils that leave a film or damage coatings. A damp microfibre cloth is a safer everyday option.
Is it safe to clean a TV with water?
Yes, if you use a cloth that is barely damp and the TV is switched off and unplugged. The risk is liquid running into the edges, not the water itself. Wring the cloth out well, wipe lightly, and dry the screen straight away with a second cloth. Distilled water leaves fewer marks than tap water.
Why does my TV screen look streaky after cleaning?
Usually too much liquid, a dirty cloth or minerals from tap water. Wipe the screen again with a clean, barely damp cloth, then buff with a dry one. Streaks are easier to see when the set is off and light falls on the glass at an angle, so check from a few positions.
Can you remove scratches from a TV screen?
Not reliably. Home remedies such as toothpaste, baking soda or polish are abrasive and will usually make the area worse on a coated screen. Light marks that look like scratches are sometimes just oil or residue, so clean gently first. For a real scratch, ask the manufacturer or a repairer about options.
Can I use compressed air on a TV?
Compressed air is fine for dust in vents, ports and gaps if you use short bursts, keep the can upright and hold it away from the set. Do not spray it at the screen. Some makers prefer a soft brush, so check the manual if you are unsure.
Do I need to unplug my TV to clean it?
Yes, switching it off at the set and unplugging it is the sensible precaution before bringing any damp cloth close to it. It also leaves the screen dark and cool, so streaks show up clearly and cleaning liquid does not dry on a warm surface.
