Heres how to clean electronics:
1 Use a damp cloth to clean the screen of a computer monitor or television. Turn off the equipment first. Distilled water is good for dampening the cloth because it doesnt contain small particles that can scratch the glass surfaces. Commercial screen cleaners, available from office-supply or computer stores, also work. Some are specifically designed for laptops.
2 Anti-static cleaners protect against dust and can also be used to clean casings for computers, printers, fax machines, televisions, phones and video and audio equipment.
3 Compressed-air dusters allow users to dust intricate areas such as computer keyboards, typewriters, telephones, photo equipment and delicate household items. To clean a keyboard, turn it upside down and blast a shot of compressed air between and under the keys. An alternative: Use a mini-vacuum cleaner to pull the dust out.
4 Wipe keys off with a damp clean cloth or use cotton swabs. Never spray liquid cleaner directly on the keyboard.
5 If a key does get stuck, unplug the keyboard and pry off the key cap. Clean the key cap thoroughly, and spray the underneath area with a contact cleaner, a type of cleaning typically used to clean electrical contacts.
6 Periodically, examine the fan on the back of the computer case. A buildup of dust and lint on the fan is a sign that theres also a buildup inside the computer. To clean that out, first unplug the system, then carefully remove the case (you may need to unscrew it). Clean the dust out with a mini-vacuum cleaner or by carefully using a normal vacuum cleaner with a small nozzle attachment.
