A method of and apparatus for the surface cleaning of workpieces, e.g. the degreasing, scale-removal and rust removal from a metallic surface, especially so as to produce a bright, clean and relatively smooth surface to receive a coating, positions the workpiece in a fluidized bed of an abrasive, such as particle of corundum or quartz sand, and directs fine jets of gas at the surface from nozzles spaced therefrom within the fluidized bed. |
