Keeping It Clean
Copyright © 2004 Chuck Nelson

We are all diligent in running our anti-virus scans, cleaning up old files and folders and removing old software. But, quite often, the physical cleanliness of the computer itself is forgotten. A dirty computer can make its use difficult and even cause hardware failure. By performing a few regular cleaning tasks, your computer will last longer and be easier to use. This is the first in a series of articles where we will discuss the best ways to clean your computer equipment and keep it running in top condition.

Cleaning Supplies and Tools

Your computer cleaning kit does not require any expensive tools or gadgets. In fact, the only tool needed is a Phillips screwdriver. I have listed all the supplies and tools below needed to keep your system clean.

• Small Phillips Screwdriver
• Can of compressed air – make sure it comes with the small tube to attach to the spray nozzle
• Cleaning towels – These should be fabric and not paper products
• Hot soapy water – Only a small amount of soap is required, dish washing liquid with a grease cutter works best
• Old used toothbrush or similar size brush with plastic or nylon bristles
• Small cup to hold screws
• Cotton tipped swabs
• Standard rubbing alcohol

Computer Case

Your computer case, or tower, is probably the most difficult to clean. Once it is clean or if it is  a new system you should clean it about once every three months. If a smoker, I strongly recommend cleaning it once a month. The cooling fans in the case draw cool air in so any dust in the air is quickly sucked into the case. This can build up causing poor air circulation resulting in over heating of the electronics. 

To clean the case, first unplug all the cables from the back and remove it from its normal position. If the case has not been cleaned for a while, take it outside to remove all the dust. Using your Phillips screwdriver, remove the 2 to 5 screws on the back. Then remove the side panel. On some older cases the entire outer shell needs to be removed. Don’t be intimidated by all the cables and wires. If you clean it carefully none of the insides will be disturbed.

Once the case is open, get your can of compressed air and blow out all the loose dirt and dust. Make sure to get around each component. If you can safely reach the blades of the cooling fans, get a wet rag or cloth and clean each of the fan blades. Plain water works best at this point. Use your can of air again to help dry off any water. Make sure the inside of the case is dry before attempting to plug it in again.

Finally, put the outer case back on and fasten the screws. The last step is to clean up the outside of the case removing any buildup that might be present. Let the case sit for at least 3 to 4 hours letting it completely dry. Please make sure that you return the computer indoors before letting it dry. The high humidity and salt content of the air in the area may cause damage to the electronic components.

Next time, we will discuss cleaning your monitor, keyboard and mouse.
