Which tool should be avoided when cleaning sensitive computer components?

1. Compressed air

2. Natural bristle brush

3. Liquid cleaning solution

4. Soft cloth

The correct answer is: Liquid cleaning solution

The option suggesting to avoid using a liquid cleaning solution is correct because liquid cleaners can pose a risk to sensitive electronic components. These components are often sensitive to moisture, and if liquid spills onto motherboards, graphics cards, or other critical areas, it can lead to short-circuiting and irreversible damage. Moreover, some liquid cleaners may contain chemicals that can corrode or degrade materials used in electronic components, which is not a risk associated with dry cleaning options like compressed air or a soft cloth. In contrast, using compressed air is typically safe for removing dust and debris from delicate areas without the risk of introducing moisture. A natural bristle brush can be effective for gently dislodging dust from hard-to-reach places, and a soft cloth is useful for wiping surfaces without scratching them. Both of these options present less risk compared to liquid cleaners, making them more suitable for maintaining the integrity of sensitive computer parts.
