Computer fans pull a lot of dust inside the chassis. If undisturbed, the dust can interfere with ventilation, eventually causing parts to fail. If you have a service contract that covers maintenance, have your computer taken apart and professionally cleaned. Otherwise, follow these steps.

Tricks & Tips

• If compressed air is too strong for little dust jobs, try using a plastic liquid medicine plunger style dispenser.

• Pull the plunger all the way back to fill it with air and then push it forward quickly for a quick output of air to blow away dust in small places such as USB ports or SD memory card slots.

• The small ends of these dispensers enable you to reach a more concentrated area with the air then you could get with just blowing our air yourself (from your mouth).

Tricks & Tips

Computer Cleaning

• When using compressed air, always release in short blasts. Longer blasts can actually result in condensation.

• Anti-static cloths are great for attracting dust and are safe to use around computer equipment.

• The cleaner you keep your work space, the cleaner your equipment will be

• Be sure to hang on to your user manuals as they provide you with the best cleaning methods for that particular device.

Printer Cleaning

1. Turn your printer off before cleaning.2. Clean the outside of your printer with a moist, lint-

free cloth. Flour sacking or 100% cotton white t-shirt material works well.

3. Usually a solution of one part vinegar and one part water is safe to use, but when moistening a cloth, be sure to wring out all the excess. Distilled or RO (reverse osmosis) water minimizes mineral residues. If you do use a prepared cleaner, make sure it is safe for both electronics and plastics.

4. Always moisten the cloth. Never spray an aerosol directly onto your printer.

3. Clean the driver in the speaker. Dust can accumulate in the drivers. When removing the dust use a soft bristle paintbrush.

4. Look for other areas within the speakers that have accumulated dust. Use a dry cloth or pant brush to remove any other dust in the speakers.

5. For sensitive small parts of the speaker use a micro-fiber cloth to remove the dust.
