Grade 4 steel wool is a coarse abrasive, ideal for heavy-duty cleaning, stripping paint, varnish, and rust from wood and metal, preparing surfaces for refinishing, or cleaning tough grime off building materials and plumbing, offering a balance of effectiveness and durability for significant surface prep work. Key Characteristics Coarse Texture: The filaments are thicker, making it good for stripping rather than fine polishing (like grades 0000). Crumble & Dust Resistant: High-quality versions are designed to stay together better during use. Versatile: Works on wood, metal, porcelain, and glass for tough jobs. any questions please ask
