Depending on the degree of formation, rust consists of several layers of iron in different oxidation states. The following are typical data for a commercial rust remover (Rust-Oleum): Remove the item from the container after 24 hours and begin scrubbing the rust off with a nonmetal scrubbing pad until as much rust is removed as will come off. They will have the opportunity to develop their own anti-rust measures, using clear nail polish, spray-on car wax, vegetable oil and other coatings. Adjust the volume to 250 μl per well (Optional) Machine cut the rusted iron samples (~1” x 1”). Remove the steel wool and put it into the other cup, placing it upside-down on the table.
