The apparatus comprised of a web of material having an abrasive surface, a rotary moving mechanism for rotatably moving the web of material around a predetermined point of the web of material, and a connecting mechanism for connecting the predetermined point of the web of material to the rotary moving mechanism. The apparatus including a cyclic moving mechanism for moving either the abrasive surface of the web of material in a cyclic pattern over and against the surface finish of the cooking vessel for a predetermined period of time or for moving the cooking vessel so that the surface finish of the cooking vessel moves in a cyclic pattern against the abrasive surface of the web of material for a predetermined period of time. The method is generally performed as follows: Adjusting the rotary moving mechanism so that it applies a predetermined pressure or force to the surface finish and so that it rotatably moves the web of material in at least one predetermined direction at a predetermined rate of speed; the direction could be one way or reversible. Bringing the abrasive surface of the material into contact with the surface finish of the cooking vessel. Actuating the rotary moving mechanism so that the abrasive surface is moved at a predetermined speed for a predetermined time while the cyclic moving mechanism moves the cooking vessel in a predetermined pattern for the predetermined time. Measuring the final thickness of the surface finish of the cooking vessel at the predetermined area of the surface finish and determining the difference between the thickness determined in step one and the final thickness of the surface finish.
