It's Not Broken ....It's Dirty

When was the last time you gave your PC a thorough cleaning?
Cars need to be serviced, carpets need to be vacuumed, floors need to be swept, windows need to be washed and, importantly, computers too need to be cleaned. Dust under the sofa may not be harmful but inside a computer it can have devasting effects.


Does your computer feel overworked? Are there times when you know it's sick? Up to 70% of computer related breakdowns are caused by dust dirt and other airborne particles. Yes, it's a fact computers do get dirty - they are a magnet to dirt and dust attracted by the static electricity that is developed by the machine. The dust accumulates both externally and internally. As the dust accumulates inside your computer (which is sucked in from the air by the machines cooling fans and barometric pressure) it creates an insulating blanket that will prevent heat from dissipating this resulting in overheating, chip burn out, fan failure complete system crashes, poor performance, loss of data etc.

Keyboardsalso become sticky and inefficient from dust and particle build up. Mice become erratic and unresponsive
Internal parts that seem not to be working correctly may be only dirty causing them to malfunction. Floppy drives, CD/DVD drives and other removable media devices also require periodic cleaning as corrosion and dust particles build up on the read/write heads and cause errors making the drive unreliable. Maybe your PC has developed an annoying rattle or hum. Hygiene too is important and cleaning will remove dust lint, bacteria, dirt, static, make-up, hair, food and general general debris such as paper clips. Keeping your system clean takes only a few hours a year but could add years to it's life. The more you can keep dust, dirt, pollen and pet hair away from your computer the better it will run.
Although cleaning a computer is no guarantee that it will work better or that you will never have any problems it does improve your chances of trouble free computing. Without regular maintenance your PC may splutter and grind to a halt leaving you stranded on the "hard shoulder of the information highway". According to IBM, the worlds largest computer company, if all the dust and contaminants were removed from the inside of all computers less than 1% would fail in a given year.


Cleaning your computer and your computer components helps keep them in working and good condition. Depending on the environment that your computer operates in determines how often you should clean your computer case printers scanners etc.

If you are an end-user or business it is recommended you clean your computer components every five months as well as doing the standard dusting as you choose keeping it looking clean.

If you are a end-user who smokes in the location of the computer it is recommend that you clean your computer components every three months as well as doing the standard dusting as you choose keeping it looking clean.

If you are a business or is a company which manufacturers any possible airborne chemicals or produces excessive amounts of dust it is recommend that you clean your computers every 2-3 months.

Information about cleaning computer components.


Why? Dirt, dust and hair can build up causing the keyboard to not function properly.

Procedure: Many people clean the keyboard by turning it upside down and shaking. A more effective method is to use compressed air. Compressed air is pressurized air contained in a can with a very long nozzle. Simply aim the air between the keys and blow away all of the dust and debris that has gathered there and by using our power cleaner. And cleaning the keyboard with a damp cloth and using the keyboard brush in-between the keys to remove any small particles or debris.

A vacuum cleaner can also be used, but make sure the keyboard doesn't have loose "pop off" keys that could possibly be sucked up by the vacuum. A vacuum attachment set makes the task much easier.

Why? If the keyboard has anything spilt into it not taking the proper steps can cause the keyboard to be destroyed.

Procedure: The following are a few recommendations to help prevent a keyboard to become bad once a substance has been spilt within it. First turn the computer off immediately. Once the computer is turned off quickly flip the keyboard over helping to prevent the substance from penetrating circuits. While the keyboard is upside shake the keyboard on a surface you do not mind getting wet or which can be cleaned up. While still upside down use a cloth to help clean out what can be reached. Once the keyboard has been cleaned the best it can, leave the keyboard upside down for at least one night. The longer it can be left without plugged in the better. Remember some attempts at cleaning a keyboard can make things worse, so only ever surface clean your keyboard.

If a keyboard does not work after having a substance spilt into it, it is recommended that it be replaced


Why? Dirt, dust, and finger prints can cause the computer screen to be difficult to read.

Procedure: The monitor screen can be cleaned with our plasma TFT/LCD cleaner. Be sure to remove power from the monitor and spray the cleaner directly onto the screen and wipe off with a clean lint free cloth. Dust off any dust with the lambs wool duster that has settled on top of the monitor, and make sure no books or papers have been placed on the air vents. Obstructed monitor vents can cause the monitor to overheat or even catch on fire.

LCD/TFT CLEANING (Traditional and flat panel display)
Why? Dirt, dust, and finger prints can cause the computer screen to be difficult to read.

Procedure: Unlike a computer monitor the LCD is not made of glass therefore requires special cleaning procedures.

To clean the LCD screen we recommend that you use plasma TFT/LCD cleaner

Why? A dirty optical-mechanical mouse can cause the mouse to be difficult to move as well as cause strange mouse movement.

Procedure: To clean the rollers of a optical-mechanical mouse you must first remove the bottom cover of the mouse. To do this examine the bottom of the mouse to see which direction the mouse cover should be rotated. the mouse cover must be moved counter clockwise. Place two fingers on the mouse cover and push the direction of the arrows.

Once the cover has rotated about an inch rotate the mouse into its normal position covering the bottom of the mouse with one hand and the bottom should fall off including the mouse ball. If this does not occur attempt to shake the mouse gently.

Once the bottom cover and the ball are removed you should be able to see three rollers located within the mouse. Use a cotton button swab and move in a horizontal direction of the rollers. Usually there will be a small line of hair and or dirt in the middle of the roller, remove this dirt and or hair as much as possible.

Once you have removed as much dirt and hair as possible clean the rollers using a cotton swab soaked in power cleaner and the mouse ball with power cleaner and a cloth. Then replace the ball and clean the mouse externally.

If the mouse still appears to be having the same issue repeat the above process, if after several attempts the mouse is still having the same issue it could be a possibility your mouse may have a hardware issue at which time it would be recommended to replace your mouse.

Why? Keeps the appearance of the computer looking new. During cleaning if ventilation locations are found these can be cleaned with an air duster helping the case keep a steady air flow to the computer keeping components cool and in good working condition.

Procedure: The case that houses the PC components can be cleaned with a lint free cloth that has been sprayed with our power cleaner. It is recommended that you never use a solvent cleaner on plastic.


Why? A dirty CD-ROM/DVD drive can cause read errors with CD discs not allowing you to install software or causing errors during the installation of software A clean CD or DVD drive will optimize data retrieval for fewer errors and prolong the life of the drive. Automatic dry cleaning system gently removes dust from the lens
Procedure: To clean the CD-ROM drive we recommend purchasing a CD-ROM/DVD cleaner. Using a CD-ROM/DVD cleaner should sufficiently clean the CD-ROM/DVD laser from dust, dirt, and hair.


Why? Dirty read/write heads on the floppy drive can cause errors during the reading and/or writing process.

Procedures: The floppy drive can be cleaned the recommended method is to purchase a kit designed to clean the read/write heads on your floppy drive. Remember to download the diskette utility program to enable this process to work correctly.

REMEMBER If your not sure or think you require professional help call in the experts.

Keeping it clean!
If cleanliness is next to godliness, we computer users are an irreverent lot! That's the considered opinion of many computer maintenance and repair specialists.

"Computers are a magnet to dirt; they can suck in dust from the air and major parts that need to be kept cool get coated with it. The result is overheating and poor performance, data loss, or even system breakdowns"

"There is a common misconception among individual and corporate computer users that their machines are indestructible. They don't realize that dust residues, skin oils and adverse environmental conditions do a lot of harm" to sensitive electronics and plastic materials.

Experts agree that simple cleanliness and regular maintenance can mean longer, trouble-free life for computers, peripherals, and other office machines. It doesn't require a lot of time or money, either.  All it takes is perhaps an hour of your time, a vacuum cleaner, CD and disk drive cleaners, compressed air duster, brushes, swabs, plus cleaning products available at most large computer and office supply stores, or via mail order.

Never use ammonia-based or abrasive household cleaning products on your computers or other office equipment!

Start your cleanup by shutting off power. Dust computer system and work surfaces, including under the monitor, keyboard, printer, etc. Vacuum around the work area. Vacuum vents on the computer case and all peripherals. Remove the case cover and ground yourself by touching the metal computer chassis or, even better, wear a grounding strap. Blow out all debris from inside the case with a compressed air duster, being careful not to damage any of the wiring or electronic components. Concentrate on the vents, fan(s), power supply, diskette and CD-ROM drive openings. Use long cotton swabs to get into crevices. 

Replace case cover. Unplug your keyboard, turn it upside down and shake gently, then use a keyboard brush to clean between the keys.

Remove screws that hold on the bottom and blow out dust and debris from the innards with an air duster. Replace the back. Follow a similar procedure with your mouse or trackball, except that you should use swabs and a power cleaner made for the job to clean the ball and positioning rollers. 

Clean your printer, too. Follow directions in your User Manual because different types of printers require different care.

Now that the insides are clean, go over the exteriors. A cleaning product like power cleaner should not be sprayed directly on surfaces. Spray it on a cleaning cloth, wipe on, then wipe off. Stubborn stains may require a second application. Use a drive cleaner disk to clean floppy and CD-ROM heads every three to six months, depending on system usage. 

Finally, make sure there are no kinks in cables and cords, and that all plugs and connectors are still properly seated after being disturbed during the cleaning process...
Computers used in homes with pets may need special care, because fur from the animals can build up on or inside air intakes. This can create serious overheating in a hurry! One technician told me of a customer who had a Border Collie that curled up at her feet while she used her computer. "She thought it was cute, until one day her system acted up and she called me in to see what was wrong. As soon as I pulled the mid-tower case out from under her desk I could see the problem. Dog hair had been sucked into the case and was clogging both the air intake areas and the fan cage! I cleaned it out well and everything was fine. She had called me soon enough to permanent damage, though her CPU's life might have been shortened by a few months." Keep this in mind if you have a pet. Keep it out of your computer room and check your system regularly to be sure they are free of fur or hair balls.


Keeping your system clean takes only a few hours a year, but could add years to its life.
