Counter brush is perfect for quick cleanups. All-plastic block features flagged polypropylene fill with 8" bristle coverage for thorough cleaning. Staggered hole pattern prevents gaps in fill material so brush sweeps up all the dirt. Dense fill leads to longer brush life & more efficient sweeping. Flagged tips pick up fine dust & dirt particles. Durable polypropylene offers good abrasion-resistance & shear / break-strength. It will not stain, discolor or absorb odors. It is resistant to solvents, acids, oils, fungus & bacteria growth. Use it wet or dry.
