This pack contains 150g of Steel Wool in Grade 3 (Coarse), representing the most aggressive and abrasive grade commonly used for heavy-duty cleaning and preparation. Grade 3 is ideal for tasks where maximum cutting and scrubbing power is required, such as removing old, heavy rust from metal surfaces, stripping multiple layers of paint or varnish from wood and metal, and heavy cleaning of rough materials like brick or stone. Due to its coarse nature, this grade is typically used for the initial stages of restoration projects where the goal is rapid material removal, rather than fine finishing.
