A device for the improvement of anti-smudging, gripping and shelf-life properties of products and surfaces comprising a low-ion plasma generator and a superheated steam generator, wherein the plasma generator and the superheated steam generator electrically generate and apply a low-ion stream, the plasma generator and the superheated steam generator each comprising a heater which heats a gaseous flow to a temperature sufficient to produce ions, wherein the gaseous flow is heated by at least one electrically powered heating element, wherein each has an aperture through which the low-ion stream exits and wherein each is positioned in a manner to project the low-ion stream individually, simultaneously or sequentially to products and surfaces.
