Read the model's care instructions
Identify the monitor or television model and find its cleaning guidance. The front surface may have coatings that are not obvious by touch or appearance. Samsung's monitor guidance, for example, starts with a clean microfiber cloth for dust and fingerprints, but the complete method should be checked for the actual product. Do not generalize a permitted liquid from one device to every display.
Turn the screen off and disconnect power as its instructions direct. A dark, cool screen can make dust and marks easier to see. Prepare a clean soft cloth reserved for displays rather than one that has already collected grit from a desk or floor. Inspect it before use; a cloth described as microfiber is not helpful if it contains abrasive debris.
Use the least intervention needed
Remove loose dust gently using the approved method, without pressing hard on the panel. Do not scrape a stubborn mark with a fingernail or tool. If the manufacturer permits a damp cloth, use only the specified liquid and amount, keeping moisture away from openings and edges. Never assume spraying the screen directly is acceptable merely because the bottle says electronics cleaner.
Clean the frame and stand according to their own material guidance. Keep the cloth used on dusty support parts separate from the one used on the panel. Avoid pushing dirt from the bezel into a seam. If a mark does not respond to the approved method, stop and consult the manufacturer rather than escalating to stronger solvents.
Prevent the next mark
Let the display dry as instructed before reconnecting power. Check the surface under ordinary lighting without repeatedly rubbing it to chase every tiny reflection. Frequent aggressive cleaning can create more risk than a small harmless speck. Keep the cloth clean and stored where it will not pick up grit before the next use.
Move the display by its supported frame or stand rather than pressing on the visible panel. Keep drinks and spray products away from the screen, and teach other household users the same care method. A short note with the model's approved cleaning instructions can prevent someone from reaching for a general-purpose cleaner simply because it is nearby.
