Rogue River Tools™ Bronze Wool pads are ideal for polishing fine wood finishes, cleaning glass, or brightening dull metal surfaces. Gentle material that can be used directly on glass surfaces without sprays. On metal surfaces, these serve to brighten by removing only the oxidized layer of metal without scratching even soft metals like copper and aluminum. Excellent for marine or outdoor uses (since steel wool fibers can rust or stain exterior surfaces) or hard, highly polished finishes such as kitchen and dining tables. Pads can be cleaned simply by shaking off vigorously or striking pad against a hard surface.
