This wire brush is highly effective for heavy duty cleaning and preparation of a wide variety of surfaces including wood, metal, brick, masonry, flags, steel machinery and unfinished metal. 4 high density rows of 5" long, heavy duty steel wire are anchored into a robust, injection moulded body, enabling it to remove rust, paint, varnish, grout, dirt, moss, algae, heavy grime, welding slag and more. The robust 10" long handle enables you to apply a firm grip for maximum purchase and ensures your hands are kept well away from both the wires and the surface being cleaned. It also features soft grip for comfort and reduced hand fatigue, especially during extended use.
