Which of the following tools is best suited for cleaning tight spaces?

The flat tip screwdriver is particularly effective for cleaning tight spaces due to its narrow blade and pointed tip, which can easily access confined areas that larger tools cannot reach. Its design allows it to scrape away dirt, dust, or debris efficiently from edges and corners, making it ideal for maintenance tasks in cramped environments, such as behind equipment or inside narrow housings.

The other tools mentioned, while useful for various mechanical tasks, are not as well-suited for the specific need to clean tight spaces. A hammer, for example, is a heavy tool meant for driving nails or breaking apart materials, rather than for cleaning. A wrench is typically used for turning nuts and bolts, which can be cumbersome in a tight space. A chisel is designed for cutting and shaping materials, and its bulk can also inhibit effective cleaning in confined areas. Hence, the flat tip screwdriver stands out as the best option for this task.
