Abstract
A process for cleansing microorganisms from the pliant epidermal surface of a human hand which comprises brushlessly scrubbing the pliant epidermal surface of the human hand with a plurality of cleansing fluids. The cleansing fluids are oscillating sprays which are sprayed onto the epidermal surface at a frequency of 20-80 HZ and at a temperature of 40-50° C. thereby removing microorganisms present on the pliant epidermal surface.
Claims4
A process for cleansing microorganisms from the pliant epidermal surface of a human, which comprises:
- 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.
