Cleaning Household Electronics Safely: Screens, Computers and Remotes

Turn the device off and unplug it, and wait for it to cool, since cleaning while running is hazardous and can damage the screen. Prepare one clean dry microfiber cloth and another barely damp with pure water, a very soft brush and a cotton swab for gaps.

Let the liquid touch the cloth, not the device, because direct spraying can seep through openings. Wring the cloth out so it does not drip, and avoid rough paper towels that can scratch screens.

Fine dust entering homes during stormy periods settles on ventilation openings of TVs, computers, routers and game consoles, blocking airflow and raising heat. In humid weather damp dust can turn into a muddy film on surfaces.

Place devices in ventilated spots away from curtains and fabrics that trap dust, leave space around vents, and do not enclose them in closed furniture. Do not put large devices directly on the floor in dusty rooms.

Use breathable fabric covers for devices that are used rarely, and follow manufacturer guidance on ventilation. In offices and dusty places a simple weekly cleaning schedule helps.

If you notice constant overheating, loud noise or frequent shutdowns, consult a repair technician rather than attempting internal cleaning yourself.
