Fly Ash Brick Machine Brush is a cleaning solution we developed for brick-making machinery. It is offered with a robust foundation base and nylon bristles, which makes it incredibly sturdy and long-lasting. The brushes are sufficiently tough to thoroughly clean the surface s of the machines. It comes in vertical rectangular form with golden yellow bristles and a white base. Fly Ash Brick Machine Brush may fit in tight spaces because of its thin design.
