.... The quenchant and any machining oils can be removed by immersion in an appropriate solvent. Glass bead is a quick method for scale removal that will not only clean but also produce etching or polishing that outlines the hardness pattern. If glass bead is not available, wire brushing, steel wool, or Scotch-Brite...
