Scrub brushes are cleaning tools designed for scrubbing surfaces to remove dirt, grime, and stains. They typically have stiff bristles attached to a handle, allowing users to apply pressure while cleaning. Scrub brushes come in various shapes and sizes, making them suitable for different tasks, such as cleaning floors, tiles, or outdoor surfaces. These brushes can be made from various materials, including plastic and natural fibers. Some scrub brushes are specifically designed for use with cleaning agents, while others are effective with just water. They are commonly used in households, commercial settings, and by professionals in the cleaning industry.
