Removing heavy rust (picture above) off steel can be accomplished successfully using an abrasive blasting process. While effective, the etched finish can be a challenge to polish. A vibratory tumbling process will remove the oxidation and leave a matte surface finish which can be subsequently polished.
These steel tubular parts were cleaned and polished in a 2-step vibratory tumbling process first using a general purpose Ceramic Media to remove the oxidation and any pitting caused by the rust (picture below left). The second step involved a Precision Ceramic Sphere to smooth out the surface finish and produce a polished surface finish (picture below right).
