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 11" 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.
