• Wipe down your computer

Dust off the outside of your computer with a soft, dry cloth at least once a week. Remove any fingerprints on the screen. If you want to use a cleaning fluid, visit a computer store to find one that’s specifically designed for your monitor type.

Regular household cleaners may damage a monitor screen, wearing away coatings.
Instead, gently wipe your screen with a soft cloth. A microfiber cloth is great for this purpose.

You can dampen your cloth with distilled or filtered water to wipe away tougher smudges. Plain water usually works, too, but filtered or distilled water will help you avoid streaks.

If heavier cleaning is needed, moisten a cloth with a 50-50 mix of distilled water and distilled white vinegar and gently rub your screen clean.

To clean the front and back of your laptop case, use a clean sponge that’s been dipped in mild dish soap and water and wrung out. Rub gently.

Make sure your computer is dry before turning it back on.

• Clean Your keyboard

Pick up your keyboard, turn it over, and gently pat it on the back to dislodge crumbs, stray hairs, and other tiny bits of dirt. If you’re having trouble removing sticky dirt, try using a cotton swab dipped in rubbing alcohol, or the cleaning mixtures mentioned above.

• Blow dust buildup out of computer vents, fans and accessories

Every three to six months, consider using a screwdriver to open your computer’s exterior case. With a can of compressed air (available at any computer store), clean the dust buildup out of the fan and the case. Put the case back together and use cotton swabs to pick up any lingering dirt on the fan vents or other small crevices on the outside of the case.

For laptops, check the manual for instructions on cleaning or safe case opening.
