Dust and dirt on circuit boards in computers and other electronic equipment can cause shorts and cause your equipment to fail to work properly. Cleaning a circuit board that's developed a layer of dirt is a simple way to attack problems that may be caused by dirt and dust buildup.
Instructions
1 Disconnect the power and open the case of your computer or other electronics equipment. Examine the circuit board for any batteries and remove them. If there is a battery on the circuit board, it will usually be a flat, disc-style battery, like those used for watches. The battery can be pulled or gently pried out.
2 Use compressed air to blow away any dust and debris that may be on the circuit board. You can use an air compressor, or compressed air in a can (see additional resources).
3 Accumulated grime can be tackled by dipping a cotton swap into rubbing alcohol and gently rubbing at the dirty areas. Be careful not to dislodge any electronic components when you're doing this.
4 Allow any moisture from the alcohol to dry and replace the cover(s) on your gear.
