Long-fibre quality steel wool made of superior, single-variety steel fibres, making it extra wear-resistant, tearproof and elastic. The gentle scraping effect of the steel fibres produces an ultra-smooth surface. When working wood, steel wool is preferred for surfaces with a strong grain structure, as the steel fibres emphasise the surface structure rather than sanding it down. It is used for intermediate sanding or matting glossy varnish and shellac surfaces. Cleans high-grade metal objects and polishes nickel-silver and brass to a mirror finish. Also perfect for plastic, stone and glass. Not suitable for use with water-based varnishes.
