  • brushlessly scrubbing the pliant epidermal surface of a human with a plurality of cleansing fluids sprayed in an ordered sequence, said fluids and sequence comprising;

    (i) first, spraying water for a first predetermined period of time on the surface of the human at an angle oblique to a surface axis of the pliant epidermal surface;

    (ii) second, spraying an aqueous solution of a detergent and a bactericide for a second predetermined period of time on the surface at said angle; and

    (iii) third, spraying an aqueous rinse for a third predetermined period of time on the surface at said angle;

    said first, second and third sprayings being fluidic sprays which are pulsating, laterally oscillating sprays at a frequency of from 20 to 80 HZ and at a temperature of from 40 to 50°

    C.;

    wherein a cleansing of the pliant epidermal surface is obtained which is substantially as effective as a surgical brush scrub of 240 seconds at said temperature.
