Before you try to take the rust off, prepare the surface with this Restore Pre-Clean, a water-soluble formulation that removes mineral oils and greases. This product is concentrated, so a 250mL bottle will actually make about 5L of pre-clean solution. Next use Restore Rust Remover Gel or Liquid to remove the actual rust from the tool. These nonacidic formulations remove rust from steel and iron but are harmless to plastics, rubbers and nonferrous materials. The Rust Remover provides protection against further corrosion. 250mL bottles. All are imported.
