Every part of a computer can become contaminated with dust from everyday environments, which can cause harm – the PC may run hotter due to dust accumulation on cooling components, screens can become increasingly dull, printers may jam, and keyboards can become harder to type on…
Display Screen: First, use a dry, soft cloth along with a fine feather duster to clean all the dust off the screen surface. For stubborn stains that are hard to remove, you can use a slightly damp soft cloth.
Be careful to avoid using cleaning products that contain alkali. A cloth can also help to reduce static electricity on CRT screens after prolonged use. For the ventilation slots on the screen, it’s best to use a vacuum cleaner to suck the dust out. Avoid using compressed air cans as they can blow dust into the internal structure of the screen.
Computer Case: When cleaning inside the computer case, remember to turn off the power and unplug all cables. When cleaning inside the case, ensure you are grounded and wear an anti-static wrist strap to prevent damage to electronic components. Use a vacuum cleaner to remove dust from areas with electrical circuits, electronic components, and slots; avoid using a cloth in these cases. Use compressed air to blow dust out of the computer case.
Scanner: When cleaning the contact surface of the scanner – where the electronic eye passes through for recognition, use a very soft, slightly damp cloth or specialized cleaning cloths for glass surfaces. Cleaning cloths or products that contain alcohol or alkali may scratch the scanner surface, degrading the quality of scanned images.
Printers and Other Devices: For laser printers, you can use specialized cleaning paper. For dot matrix printers, it is advisable to run a light cleaning cycle. If ink spills occur in the printer core, the best solution is to remove the core for cleaning.
For regular mice, you can use a vacuum cleaner, compressed air, or a regular cloth to clean the outer surface along with the mouse ball and the sliding rod. For optical mice, it’s best to clean the light-emitting surface with a soft cloth dampened with alcohol. Remember to thoroughly clean the cable system and mouse connectors. For keyboards, use a vacuum cleaner to suck up dust, a fine brush, or a soft cloth. Keep in mind never to remove the keys for cleaning as this can damage your keyboard.
