THE METHOD OF REMOVING IMPACTED DEBRIS ENTRAINED IN THE MINUTE CAVITIES OF A SURFACE TO BE CLEANED WHICH INCLUDES; IMMERSING THE SURFACE TO BE CLEANED IN A CLEANING FLUID; IMMERSING IN SAID CLEANING FLUID THE WORKING FACE OF A VIBRATOR ASSEMBLY WHICH IS DESIGNED AND POWDERED TO VIBRATE ITS WORKING FACE AT AN AMPLITUDE IN THE ORDER OF ONE-HALF TO THREE-THOUSANDS OF AN INCH AND AT A FREQUENCY IN THE RANGE OF FIVE TO FIFTY KILOCYCLES PER SECOND; ADJUSTING THE RELATIVE POSITION OF SAID FLUID IMMERSED WORKING FACE WITH RESPECT TO THE FLUID IMMERSED SURFACE TO BE CLEANED SO THAT SAID WORKING FACE IS IN CLOSE PROXIMITY TO BUT DOES NOT PHYSICALLY CONTACT THE SURFACE TO BE CLEANED WHEN VIBRATED; ENERGIZING SAID VIBRATOR ASSEBLY TO VIBRATE ITS WORKING FACE AT A FREQUENCY WHICH WILL GENERATE A COLUMN OF COMPRESSIONAL WAVES IN SAID CLEANING FLUID OF SUCH CHARACTER THAT THE FIRST QUARTER OF SAID COMPRESSIONAL WAVES EXTEND SUBSTANTIALLY NORMAL TO SAID WORKING FACE AND ARE OF SUFFICIENT LENGTH TO MORE THAN FULLY PENETRATE THE FULL DEPTH OF THE DEBRIS IMPACTED SURFACE CAVITIES DEFINED WITHIN A COLUMN AREA CORRESPONDING TO THE AREA OF SAID WORKING FACE, AND WHEREBY THE IMPACTED DEBRIS CONTAINING CAVITIES WITHIN SAID COLUMN AREA WILL BE SUBJECT TO THE INTENSE CAVITATIONAL ACTION OF THE CLEANING FLUID EMBRACED WITHIN SAID FIRST QUARTER WAVELENGTH ZONE; AND CONTINUING SAID CAVITATIONAL ACTION UNTIL THE IMPACTED DEBRIS HAS BEEN DISLODGED FROM THE SURFACE CAVITIES.
