Cleaning & odor

3 minute read · Shared guidance for televisions

Clean the screen with minimal pressure

Modern TV panels are thin and their surface coatings can be damaged by pressure, solvents, or abrasive materials. LG’s screen-care guidance says to turn the television off, let it cool, and use a clean, dry microfiber cloth with gentle one-direction strokes. For stubborn marks, LG describes lightly dampening a cloth rather than applying liquid to the screen, followed by immediate drying. Samsung also cautions against spraying liquid directly onto the screen and recommends a soft microfiber approach. Follow the cleaning instructions for the exact set if they differ.

Do not press on a smudge to make it disappear faster. LCD and OLED panels can show temporary marks when stressed, and concentrated pressure can permanently damage the panel. Clean only the visible surface; do not push a cloth into the bezel seam, speaker openings, ventilation slots, or connector area. If a mark remains after a gentle pass, stop and identify whether it is residue, a scratch, or damage beneath the surface. Repeated rubbing cannot repair a coating scratch or internal blemish.

Use a cloth, not a sprayed screen cleaner

Switch the TV off and disconnect power if the manufacturer’s care instructions recommend it. Let the panel cool before wiping. Use a clean, lint-free microfiber cloth reserved for delicate screens; cloths used with furniture polish, household cleaner, or fabric softener can transfer residue. Begin dry. If the manufacturer permits moisture, dampen a small area of the cloth with the specified liquid—LG advises a lightly damp cloth for persistent marks, while Samsung’s guidance specifies distilled water for its procedure. Do not assume that glass cleaner, alcohol, ammonia, disinfectant, or a commercial “screen spray” is safe for every coating.

Never spray the display itself. Liquid can run into the lower bezel and reach electronics or optical layers. Keep moisture away from vents, buttons, and ports. Wipe the screen dry with another clean microfiber cloth if the care guidance calls for it, then wait until the surface is dry before reconnecting power.

Clean the cabinet and ventilation separately

The screen and cabinet do not necessarily share the same cleaning instructions. Use a soft cloth on the cabinet and stand, and avoid abrasive pads that can scratch painted or glossy finishes. Do not apply polish or solvent around the bezel where it could wick onto the display. For dust at ventilation openings, remove loose dust from the outside without inserting a tool or cloth through the grille. The openings allow heat to escape; blocking them with a cleaning cloth or pushing debris inward defeats the purpose of cleaning.

Check that the TV is unplugged before cleaning around connected ports. Do not use a wet cotton swab inside HDMI, USB, antenna, or power sockets. If a port has visible contamination, corrosion, or liquid residue, leave it unused and request qualified service rather than scraping the contacts. Cleaning is for loose surface dust, not a remedy for a damaged connector.

Stop when the surface suggests damage

A fingerprint should usually change as the cloth crosses it. A fixed vertical line, dark patch, cloudy region, or color change that remains in the same place when the source changes is not ordinary surface dirt. Avoid using a stronger chemical or more pressure to test it. Photograph the area with the TV displaying a plain image and contact the manufacturer or seller with the model and purchase details.

If liquid has been sprayed or spilled onto the screen, turn the set off and disconnect it if safe to do so; do not power it back on merely to see whether the picture works. If liquid reached openings, arrange service. Keep the product manual and warranty terms at hand, because unauthorized disassembly or chemical cleaning can affect service eligibility. LG and Samsung publish distinct screen-care guidance; the set’s own instructions remain the controlling procedure.
