A cold plasma jet hand sanitizer and method of use are provided. A pair of opposing two-dimensional arrays of atmospheric pressure cold plasma jets is used to create a sterilizing volume. Any object placed into that volume will have its surface sterilized. The opposing arrays of plasma jets are operated electrically 180 degrees out of phase so that the opposing arrays of plasma jets essentially fire into each other in the absence of an intervening object, or directly impinge on the surface of an intervening object.
