How to Remove Dust from Computer


In today’s age and time, we all find ourselves surrounded with various forms of technology at home. We not only get to deal with software maintenance but also physical maintenance. The most common problem we find is dust and dirt, and we don’t always know how to clean the delicate hardware components.

Dust can cause major problems with our computers for dust can build up in and on our system, and can cause the computer to get overheated  due to the fact that it blocks vital air flow points. But there are various ways to minimize the dust build-up and clean the dust away fast and safely. As we all know, prevention is better than cure. To minimize the build up of dust on the computers components try to avoid smoking, drinking and eating around your computer and avoid placing your computer directly on a carpeted or wooden surface.

When cleaning your computer, try and use only the following items:
    • Cloth – Dampen, and for external use only
    • Rubbing Alcohol – Preferred choice over water
    • Portable Vacuum Cleaner – For vacuuming around your system
    • Cotton Swabs – Small, hard to reach places
    • Soft Paint Brush – Especially useful for fans

Here are a few cleaning tips to keep in mind when cleaning your computer:
• Avoid any fluids in or around your computer. If it is needed to spray or wash anything, use a dampen cloth on the exterior of the computer, but never inside it.
• Vacuum around the computer system, and never inside it, for the device causes a static pulse which may damage the internal components.
• Ensure your computer is off when cleaning it.
• Never clean with solvents
• When cleaning the fans, hold it firmly in place to prevent the blades from turning.

To clean the inside of the computer you can typically remove a side of the case by removing two or three screws from the back and sliding the case off. Before cleaning the inside of the computer be sure to unplug it from all power sources as it is very easy to cause a short and damage system components. With the case side removed you may blow the dust and dirt out using compressed air and or a vacuum. Make sure to blow out the dust which gathers around the cpu fan on the motherboard. This buildup causes excessive heating of components and early failure. With as much dust as we have in the Imperial Valley, cleaning at least every 6 months will significantly prolong the life of your system.
