Which two tools are commonly used to clean the inside of a computer?

1. Compressed air and natural bristle brush

2. Vacuum cleaner and cloth

3. Liquid cleaner and sponge

4. Wire brush and duster

The correct answer is: Compressed air and natural bristle brush

The use of compressed air and a natural bristle brush is a highly effective method for cleaning the inside of a computer. Compressed air is specifically designed to blow dust and debris out of hard-to-reach areas, such as fans, heat sinks, and other components that can accumulate dust over time. This is crucial, as excessive dust buildup can lead to overheating and hardware failure. The natural bristle brush complements the compressed air by gently sweeping away dust from surfaces without risking damage to sensitive components. Its soft bristles help to dislodge dust without causing scratches or static discharge that could harm internal parts. Together, these tools provide a reliable approach to maintaining a clean and functional computer environment. In contrast, using a vacuum cleaner might generate static electricity, which can damage electronic components, while cloths might leave lint or can inadvertently create static as well. Similarly, liquid cleaners and sponges could introduce moisture, posing a risk to electronic components. Therefore, the combination of compressed air and a natural bristle brush stands out as the safest and most effective cleaning method for computer interiors.
