1. A process for cleansing a pliant surface of an object, including a human, of microorganisms which comprises;
- selecting an area of the pliant surface for cleansing;
providing an oscillatory jet spray of a cleansing solution, said jet spray providing a lateral, as opposed to axial, pulsation on the surface, pulsation being in resonance with the dynamics of the pliant surface that is to be cleaned, the laterally sweeping motion of which thereby increases the flushing/rinsing effectiveness of material removal and avoids the problem of further embedding materials and bacteria into the surface; and
directing the oscillatory jet spray upon the area for a time sufficient to achieve a desired degree of cleansing.

Abstract
Fluidic oscillators are used to apply pulsatile sweeping streams of a liquid, preferably a cleansing solution, to selected areas of epidermis in a manner consistent with the resonant characteristics of the epidermis. The device thereby cleanses the skin, pores, and folds of microorganisms.

11. Apparatus for cleansing microorganisms from surfaces which comprises:
-
means having at least one nozzle which accelerates a liquid to form a jet, means for supplying a fluidic stream for cleansing, under pressure of 30 to 70 psi at the nozzle without the use of electricity to power the supply, connected to means for laterally oscillating and spraying a pulsating fluidic stream; means for laterally oscillating and spraying the pulsating fluidic stream said stream being comprised of different compositions for wetting, washing and rinsing operations, for effective cleansing of a selected area;
means for controlling the time that the fluidic stream is oscillated and sprayed; andmeans for directing the fluidic stram on the surface as a spray for a time sufficient to achieve a desired degree of surface cleansing. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)

37. A process for cleansing microorganisms from a pliant epidermal surface of a human hand, which comprises;
-
brushlessly scrubbing the pliant epidermal surface of a human hand with a plurality of cleansing fluids sprayed in an ordered sequence, said fluids and sequence comprising; (i) first spraying water for a period of at least about 20 seconds on the surface of the hand at an angle oblique to the surface axis; (ii) second, spraying an aqueous solution of a detergent and a bactericide for a period of at least about 30 seconds on the surface at said angle; and (iii) third, spraying an aqueous rinse for at least about 10 seconds 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 a temperature of from 40 to 50°
C.;whereby a cleansing of the hand is obtained substantially equivalent to a surgical brush scrub of at least about 120 seconds at said temperature. - View Dependent Claims (38, 39, 40)
