Computers constantly have dusty fans, fingerprints on compact discs and devices etc. They can get quite dirty very easily from normal everyday use. If a layer of dust is present, it will act like a blanket on the motherboard, heat sink and other components, preventing heat from escaping. Overheating causes eventual disaster. Corroded chips cannot transfer data effectively, resulting in interruptions, or even complete stoppage of data processes. Metallic dust can cause electrical shorts and is especially destructive.
When working around electronics there are some precautions that should always be taken when cleaning. It’s important to power off the system first and to use an anti-static wristband or mat. Never work on carpeted surfaces and never spray cleaning fluids directly onto computer components. Always spray the cleaner onto a cloth then wipe. Do not allow any cleaner to run or drip near circuit boards, or near seams on device casings and allow circuits or electronics to become damp or wet.
To clean the build-up of dust from inside your computer case, use compressed air to clean around the fans, power supply and areas where the dust is building up. Be careful not to aim the air directly towards any circuit board or electronic components in the case. Use short blasts and arm movement to direct the falling dust outside of the case.
You can use the small brush to dislodge dust in areas where the compressed air did not remove the build-up . You can also use the brush to wipe dust away from the inside case walls and the wires. If dust has fallen down to the bottom of the case, dampen the anti-static cloth with the electronics cleaner and wipe along the bottom of the case to remove it. You can also use the damp cloth to wipe all around the metal case of your tower and the cover.
