This stuff looks like it would be a lot better than chore boy. As I previously posted I bought the "cheap" copper plated steel scouring pads and used those. The PROBLEM I FOUND with chore boy (pure copper) is that they do not seem to have sharp edges, and don't seem to cut into the lead, rather just rubs on top of it. They work but take a long time to remove large amounts of copper. The copper plated steel ones ( got em at dollar tree ) are really sharp edged. We use stainless scouring pads to clean pots and pans and the copper plated steel ones work much much better at cleaning pots and pans also because of this apparent sharp-edgedness. My guess is that these "Big 45" cleaners are sharp also.
