We recommend working on the oil first with a mild cleaner (like Dawn dishwashing liquid) before applying more unpleasant products (like solvent based cleaners); light rust may conveniently disappear. 4/0 steel wool should also remove the rust. Wash everything well with water once the rust is removed; you can apply the Jax while the steel is still wet. Wash the metal well and dry. Do not let the steel air-dry as this may cause additional rust and/or drying marks.
